外文翻譯：英文原文：Coal Face transport equipment SelectionAbstract) Coal Face Selection of appropriate transport equipment or direct impact on the mining production to be normal, On the various drag conveyor、reversed loader、pick-a-back conveyorThe characteristics of，And how the application of the selection, for reference.Keyword) conveyor ;lectotype;capability; principle 1、Coal Face transport equipment SelectionTraction linked by the number and arrangement can be divided into single-scraper conveyor chain, bilateral links, double-center chain and the three links, and other four types. These bilateral links to various functions AFC Coal conditions, the use of a wider scope, the disadvantage is that there are two bilateral chain linked Shouli Bu absorbed phenomenon. Three bilateral links in the chain scraper conveyor developed on the basis of When the two chains not enough strength, an increase of a middle chain, the practice has proved that such a structure chain Shouli Bu absorbed form of the phenomenon than the bilateral chain scraper conveyor more serious, frequent Duanlian accidents, products are eliminated. Two-center chain-type compared with the bilateral links, the chain of uniform, bending performance advantages, but in the hard coal! Meikuai circumstances of the larger transportation to perform well. Small scraper conveyor single chain of more, but with the large-diameter circle in the chain, the chain increased strength, the German use of large-diameter circle of chain-linked heavy AFC, this form of chain conveyor To bear the load in the same circumstances, than the double-stranded chain of specifications to be larger.a) Scraper conveyor of the transmission capacity must be equal to or greater than Shearer or the production capacity of coal plough. But Shearer face conveyor and the productive capacity of roadway with the mining area, transport roadway and upgrade the mine's transport capacity of the infrastructure, the ability to prevent face-off, mining area or roadway and a lack of transport capacity “ Kabo Zi “phenomenon. Scraper conveyor structure and form of traction Shearer, and walk-oriented institutions! Bracket and the end of Slipper of the supporting structure;b) Scraper conveyor length of the chute and hydraulic support to match the widthc) Scraper conveyor of the chute and hydraulic support the passage of the jack and connect devices with space to match;d) Conveyor of the chute to rugged wear-resistant structure, a flexible;e) In order to reduce Duanlian accidents, linked ring in the large-diameter, high-intensity direction;f) Priority choice of two-motor-driven double-nose, to reduce the transmission size, the largest chain to reduce tension, reducing the nose and tail of the top area of control. Selection of priority short nose and short tail, but the head-and tail-in or corner of the plate should not be too large to reduce the pressure in the chain block friction loss.2、reversed loader lectotype of principle Bridge reproduced machine is actually a special structure of the heavy scraper conveyor, in the face conveyor section Pingxiang and scalable conveyor belt between the role of a reprint.a) Reprint of the transportation capacity to be slightly larger than face scraper conveyor. To this end use of increased chute section (on both sides of the chute and baffle), increase speed linked (to change the second-reducer gear transmission ratio) or shorten the distance between scraper, and other measures;b) Reprint of the gear in the nose of uniform, should be based on volume and distance to determine the size of the electrical power and the number of Taiwan. Priority should be optional single-motor drive, when the volume and greater distance, the optional dual-motor drive. Its transmission should try and face the same scraper conveyor to GM;c) Reprint of the aircraft tail and face the conveyor connected to the matching. A lap and non-overlap in two forms, regardless of what form, should ensure that face scraper conveyor nose of a certain height unloading (normally 600 ~ 700 mm), in order to avoid face-scraper conveyor Linked to the end of coal;d) Reprint of the nose are loaded walk in the small car, walking the structure and gauge car with retractable belt conveyor tail-supporting;e) Reprint of the bridge deck and the Department of retractable conveyor belt of coal by the tail of the length of the overlap should be complementary;f) Machine parts and reproduced the face scraper conveyor should do everything possible to GM, to facilitate the supply of spare parts and maintenance.3 Retractable belt conveyor of the principle of selectionScraper transport planes from the coal face, reproduced as bridge-to-trough uninstall the retractable belt conveyor, and then coal from Pingxiang transported to the section on the downhill or with the station. With the face of advancing to the section Pingxiang transport equipment to a more flexible elongate or shorten. Retractable belt conveyor is characterized by a set of certificates with its devices, this device from the temporary storage tape from the appropriate role, when the mobile tail, the reservoir with a corresponding device can be released or save a certain length of the belt.a) Mining machine with the transport section of Pingxiang general optional retractable belt conveyor, and its production capacity to match reprint machine. According to choose a suitable throughput with bandwidth and speed;b) Retractable belt conveyor for the laying of the general length of 500 ~ 1000 m-Taiwan, when a length of two series can not. Can also choose multi-driven conveyor belt, the length of up to 2000 ~ 3000 m;c) Conveyor belt transmission device generally used double-drum drive, and priority should be optional single-motor drive, to avoid the load due to the electrical transmission equipment caused by the unequal distribution of power increases. When the single-motor power shortage # optional two-or three electrical transmission;d) Storage devices with the activities of a drum, two and three (corresponding certificates with a two-tier, six and four storeys) should give priority to the simple structure of single-cylinder structure. If the reservoir with a shorter length of the warehouse, they can choose two or three roller structure;e) Tighten the structure of a device automatically tighten (adjustable tensioning force) and non-automatic tensioning device two categories, priority should be given to choose the former, to ensure that the tape is the appropriate tension;f) Transmission drum machine or a head band of anti-skid tape and driving drum 9 skid) security installations and non-security devices are to choose the former, in order to prevent the tape skid cause serious damage or excessive temperature rise caused by adhesive tape on fire Incidents. Ordinary canvas with a belt and high-strength nylon with two batteries, should try to choose the latter, to reduce the thick belt, increasing distance. Tape a general belt and fire tape, the latter should be used to prevent fires.g) Shift the tail installed with hydraulic and electric winch-and Fully-supporting, a pumping station system for emulsion priority should choose the former, no pumping station system can choose the latter;h) Retractable belt conveyor by the tail on the length of the form and structure to be reproduced with the bridge of the bridge and walk the length of the overlapping structure of the Department of match;i) Retractable plastic belt conveyor structure of the body-hanging wire rope, steel Hanging-beam steel frame and floor-variety. Type of steel wire rope hanging with little, simple equipment, suitable for floor changes, easy to water conditions, but the operation to shorten the tail relatively trouble. Steel-framed floor-simple structure, demolition of convenience, is conducive to the use and maintenance, but the fuselage large amount of steel used, the floor changes have an impact on the rack, under specific circumstances appropriate choiceCape pushing high-grade coal face in the course of mining, will often encounter some fault ramps National Chiao Tung University (H 3m)-not pushing too hard, making a face similar to the fault system between the “triangle“-shaped pillar, the pillar under the triangular Fault can be divided into the direction of “being“ triangle and the “inverted“ triangle of two. More recycling of coal resources, the inverted triangle coal-mining, are often used along the fault trend, retaining a fault-coal, transport, dig a supplementary entry, face additional transport along the roadway normal progress, but added the roadway and transport planes To retain a mining method, that is reproduced after the maintenance of mining.It is the most important feature: the direction of promoting the face of coal and reprint the opposite direction. The dig-mining technology to the maintenance of mining after another development, it mainly refers to one side of boring mining Lane added transport, mining technology is a supplement.1 After the set of maintenance and exploitation of the significance of the dug-mining applicationsThe work in front of the National Chiao Tung University inclined to expose fault, not hard-pushed the inverted triangle formed coal-mining, there are two under the conventional mining method: wear-mining and mining. --Will often result in-prone forward, the old waste pond falling keep up with all the top row, back-to bring greater difficulty and lower efficiency. When the old pond and a hanging roof suddenly falling, it will cause massive waste overturned cut the top row pillars, a spray men Zi phenomenon, to bring greater security threat. So for mining, mining face prone to a certain level will not be able to continue to promote the coal recovery rate is not high. The recovery of lower coal mining wear, can only reach 60 percent, the same need to fill the excavation, Lane added, using artillery and mining will consume a large amount of explosives, detonators high costs, risks, prevention-management is also very difficult, there More hidden dangers. By comparison, a reprint after the maintenance of mining coal mining face can guarantee the normal advance, and can increase the recovery rate, the district's high yield and high efficiency to promote the building of a higher value.Under normal circumstances, reproduced in the former mining machine after maintenance, ahead of meeting the need to add the roadway excavation and the laying of good reproduced directly to the recovery teams used, which would involve tunneling unit of energy, the occupation of certain human, material and Supporting material from consideration, construction of the tunnel boring the general-shelf support, and a steel support. In the latter role in maintaining pressure on the roadway, the steel roof will be a lot deformation, it is difficult to retracement, but can not reuse, then try the coal-mining teams from their own side tunneling transport Lane added, while maintaining a post-mining method, that is - Mining excavation techniques. Construction used hydraulic prop legs to replace the steel shelf-shelf support, a flexible support, reducing the pressure on the roadway, improve the supporting effect.2 Reprint after the maintenance of the technical requirements of mining① With the face forward, added the roadway, while retaining the support not back, on top of the alley, along the direction of the dumping Dou reservations Face the bottom of the first three rows of regular pillars.② To reduce air-side of falling coal pillars of pushing pressure, three rows of stranded in a timely manner to the use of hinged roof beam to the pillars, roof beam along the tendency to use the hinged support, a pillar of the reform may not be behind all face Top ranked.③ After the maintenance of Zhu Liang to set up, the first branch after the change, post-wear Muxie established to reduce the latter part of the pillars of the end of drilling. Reprint of the above two rows of pillars as sidewalks, width of 1. 0m, the spacing between the two groups Zhuliang to 1. 0m, most Shangyi Pai pillars and columns to file additional intensive pillars to prevent channeling rock.④ After the maintenance period to reduce the pillars of the deformation, to facilitate the work of retracement along the roadway after the maintenance of the pillars of Shangyi Pai, located at 8 m with a wood pile to strengthen support and maintenance of the roadway after the hand for cleaning up to ensure that the roadway Height of not less than 1. 6m.Development prospectsWith the coal mining life of the reduced recoverable reserves of less and less, and with the deep development, more and more complex geological conditions, 1.30, in more and more coal, therefore, how the limited resources, improve the coal recovery rate, And to resolve the To follow the more mining, will be in a very long topic, so for high-end after the maintenance of general mining and mining-excavation and mining technology provides a broad prospects for development, the promotion of a certain

采面刮板運輸機的選型按牽引鏈的數(shù)目及布置方式可將刮板輸送機分為單鏈、雙邊鏈、雙中心鏈和三鏈等四種類型。 其中雙邊鏈刮板輸送機能適應(yīng)各種煤質(zhì)條件，使用范圍較廣，缺點是雙邊鏈存在著兩鏈受力不勻的現(xiàn)象。 三鏈是在雙邊鏈刮板輸送機的基礎(chǔ)上發(fā)展起來的，當(dāng)兩條鏈子強度不夠時，中間又增加了一條鏈子，實踐證明，這種結(jié)構(gòu)形式的鏈子受力不勻的現(xiàn)象比雙邊鏈刮板輸送機更嚴重，經(jīng)常發(fā)生斷鏈事故，屬于淘汰產(chǎn)品。雙中心鏈型與雙邊鏈型相比，有鏈受力均勻，彎曲性能好的優(yōu)點，但在煤質(zhì)較硬!煤塊度較大的情況下運輸效果不佳。小型刮板輸送機單鏈型較多， 但隨著大直徑圓環(huán)鏈的出現(xiàn)，鏈子強度提高了，德國多采用大直徑圓環(huán)鏈的單鏈重型刮板輸送，這種形式輸送機的鏈子在承受相同負荷的情況下，比雙鏈型的鏈子規(guī)格要大一些。a)刮板輸送機的輸送能力必須等于或大于采煤機或刨煤機的生產(chǎn)能力。但工作面輸送機和采煤機的生產(chǎn)能力要與采區(qū)巷道、運輸大巷以及整個礦井的運輸提升能力相配套，以防止工作面能力過大，采區(qū)或大巷運輸能力不夠而出現(xiàn)“卡脖子”現(xiàn)象。 刮板輸送機的結(jié)構(gòu)形式必須與采煤機的牽引力機構(gòu)、行走及導(dǎo)向機構(gòu)!底托架及滑靴結(jié)構(gòu)等相配套；b)刮板輸送機的溜槽長度要與液壓支架的寬度相匹配；c) 刮板輸送機的溜槽與液壓支架的推移千斤頂?shù)倪B接裝置和配合間隙要匹配；d) 輸送機的溜槽結(jié)構(gòu)要堅固耐磨，具有可彎曲性；e) 為了減少斷鏈事故，圓環(huán)鏈朝著大直徑、高強度的方向發(fā)展；f) 優(yōu)先選用雙電機雙機頭驅(qū)動方式，以減小傳動裝置尺寸，降低鏈子最大張力，減小機頭和機尾的控頂面積。優(yōu)先選用短機頭和短機尾，但機頭架和機尾架中板的升角不宜過大，以減少在壓鏈塊的摩擦損失。2 橋式轉(zhuǎn)載機的選型原則橋式轉(zhuǎn)載機實際上是一臺結(jié)構(gòu)特殊的重型刮板輸送機，在工作面輸送機與區(qū)段平巷可伸縮膠帶輸送機之間起到轉(zhuǎn)載的作用。a) 轉(zhuǎn)載機的輸送能力要稍大于工作面刮板輸送機。為此多采用增大溜槽斷面(在溜槽兩側(cè)加擋板)、增大鏈速( 改變減速器內(nèi)第二級齒輪傳動比)或縮短刮板間距等措施；b) 轉(zhuǎn)載機的傳動裝置均布在機頭，應(yīng)根據(jù)運量和運距大小來確定電機功率和臺數(shù)。 應(yīng)優(yōu)先選用單電機傳動，當(dāng)運量和運距較大時，可選用雙電機傳動。 其傳動裝置應(yīng)盡量與工作面刮板輸送機相同，以便通用；c) 轉(zhuǎn)載機的機尾部與工作面輸送機的連接處要配套。 有搭接和非搭接兩種形式，無論采用哪種形式，都應(yīng)保證工作面刮板輸送機機頭有一定的卸載高度(一般為 600~700 )，以避免工作面刮板輸送m機機底鏈回煤；d) 轉(zhuǎn)載機的機頭均裝在行走小車上，行走小車的結(jié)構(gòu)及軌距應(yīng)與可伸縮膠帶輸送機機尾部配套；e)轉(zhuǎn)載機的橋身部與可伸縮膠帶輸送機的機尾受煤部的重疊長度應(yīng)配套；f) 轉(zhuǎn)載機的零部件與工作面刮板輸送機應(yīng)盡可能通用，以利備件供應(yīng)和維修。3 可伸縮膠帶輸送機的選型原則由工作面刮板運輸機的煤炭，經(jīng)橋式轉(zhuǎn)載機卸裝到順槽的可伸縮膠帶輸送機上，然后把煤炭從區(qū)段平巷運到上下山或裝車站。隨著工作面的推進，要求區(qū)段平巷運輸設(shè)備能夠比較靈活的伸長或縮短?？缮炜s膠帶輸送機的特點是它有一套儲帶裝置，這套裝置起暫時儲存起適量膠帶的作用，當(dāng)移動機尾時，儲帶裝置可相應(yīng)地放出或儲存一定長度的皮帶。 a)機采配合的區(qū)段平巷運輸一般選用可伸縮膠帶輸送機，其生產(chǎn)能力要與轉(zhuǎn)載機相匹配。 根據(jù)輸送量選擇合適的帶寬和帶速；b)可伸縮膠帶輸送機的鋪設(shè)長度一般為 500~1000m 臺，當(dāng)一臺長度不夠時可串聯(lián)兩臺。 也可選用多段驅(qū)動的膠帶輸送機，其長度可達2000~3000m;c) 膠帶輸送機傳動裝置一般采用雙滾筒傳動,且應(yīng)優(yōu)先選用單電機傳動,以避免由于多電機傳動負荷分配不均造成設(shè)備功率增大. 當(dāng)單電機功率不足時#可選用雙或三電機傳動;d) 儲帶裝置的活動滾筒有一個、兩個和 3 個(相應(yīng)儲帶兩層、四層和六層）應(yīng)優(yōu)先選擇結(jié)構(gòu)簡單的單滾筒結(jié)構(gòu)。 若要求儲帶倉部分長度較短時，可選用兩個或 3 個滾筒結(jié)構(gòu)；e) 拉緊裝置的結(jié)構(gòu)形式有自動拉緊（可調(diào)整拉緊力）和無自動拉緊裝置兩類，應(yīng)優(yōu)先選用前者，以保證膠帶具有合適的拉緊力；f)傳動滾筒或機頭部有帶防滑 9 膠帶與傳動滾筒打滑）安全保護裝置和不帶安全保護裝置兩種，應(yīng)選擇前者，以避免由于膠帶打滑造成嚴重損壞或溫升過高而引起膠帶著火的事故。 膠帶有普通帆布帶和高強度尼龍芯帶兩種，應(yīng)盡量選用后者，以降低帶厚，增大運距。膠帶有一般膠帶及防火膠帶，應(yīng)選用后者，以防火災(zāi)。g)移機尾裝置有液壓式及電動絞車式， 與綜采配套，有泵站系統(tǒng)供乳化液者應(yīng)優(yōu)先選用前者，無泵站系統(tǒng)者可選用后者；h) 可伸縮膠帶輸送機的機尾受載部的長度和結(jié)構(gòu)形式要與橋式轉(zhuǎn)載機的橋身部重疊長度及行走部結(jié)構(gòu)形式相匹配；i) 可伸縮膠帶式輸送機的機身結(jié)構(gòu)有鋼絲繩吊掛式、鋼梁吊掛式和鋼架落地式多種。鋼絲繩吊掛式的鋼材用量少，設(shè)備簡單，適于底板變化、容易積水的條件，但縮短機尾的操作比較麻煩。鋼架落地式結(jié)構(gòu)簡單，拆卸方便，有利于使用和維護，但機身用鋼材量較大，底板變化對機架有影響，可根據(jù)具體情況適當(dāng)選用。高檔普采工作面推采過程中,往往會遇到一些斜交大斷層(H 3m)而無法平推硬過,使得工作面與斷層之間構(gòu)成近似“三角”形煤柱,三角煤柱根據(jù)斷層的走向可分為“正”三角形和“倒”三角形兩種。為多回收煤炭資源,對于倒三角煤柱的開采,往往采用沿斷層的走向,保留出斷層煤柱,外掘一條補充運輸巷,工作面沿補充運輸巷正常推進,但對補充運輸巷及運輸機進行保留的一種開采方法,即轉(zhuǎn)載機后維護開采。它的最大特點是:工作面推進方向與轉(zhuǎn)載機運煤方向正好相反。而邊采邊掘技術(shù)是對后維護開采的另一發(fā)展,它主要是指一邊開采一邊掘進補充運輸巷,是對回采技術(shù)的一項補充。1、 載機后維護開采的意義及邊采邊掘的應(yīng)用對于工作面前方揭露斜交大斷層,無法平推硬過而形成倒三角煤柱開采時,常規(guī)下還有兩種開采方法:調(diào)采及穿采。調(diào)采往往會造成工作面呈俯采推進,老塘冒落的矸石緊跟切頂排,給回柱工作帶來較大難度,降低工作效率。而且當(dāng)老塘出現(xiàn)懸頂突然垮落時 ,會造成大塊矸石推倒切頂排支柱 ,出現(xiàn)噴門子現(xiàn)象 ,給安全帶來較大威脅。因此調(diào)采時,工作面俯采到一定程度就不能繼續(xù)推進 ,煤炭回收率不高。而穿采煤炭回收率更低 ,最多只能達到 60 %,同樣需要先補掘補充運輸巷 ,并且采用炮采會消耗大量的炸藥、雷管 成本高、風(fēng)險大 ,通防管理難度也很大 ,存在較大的隱患。相比較而言 ,采用轉(zhuǎn)載機后維護開采既可保證回采工作面的正常推進 ,又可以提高回收率 ,對于區(qū)隊的高產(chǎn)高效建設(shè)有較高的推廣價值。一般情況下 ,在進行轉(zhuǎn)載機后維護開采前 ,需要提前補掘補充運輸巷 ,并鋪設(shè)好轉(zhuǎn)載機直接交給回采區(qū)隊用 ,這會牽扯掘進單位的精力 ,占用一定的人力 ,物力 ,而且從支護材料上考慮 ,掘進施工的巷道一 般采用架棚支護 ,屬鋼性支護。在后維護巷道壓力的作用下 ,鋼棚會大量變形 ,很難回撤 ,而且不能復(fù)用 ,于是嘗試了由采煤區(qū)隊自己邊掘進補充運輸巷 ,邊進行后維護開采的方法 ,即邊采邊掘技術(shù)。施工中用單體液壓支柱代替鋼棚腿進行架棚支護 ,形成柔性支護 ,減少了巷道壓力 ,提高了支護效果。 2 、轉(zhuǎn)載機后維護開采的技術(shù)要求①隨工作面推進 ,除保留補充運輸巷的支護不回外 ,靠運輸巷上方 ,沿傾鈄方向保留工作面下端頭處三排正規(guī)支柱。②為減少采空側(cè)冒落矸石對支柱的推壓力 ,及時把三排滯留的頂梁走向鉸接使用的支柱 ,改為頂梁沿傾向鉸接使用的支護方式 ,支柱的改設(shè)不得落后工作面切頂排。③后維護段柱梁的改設(shè) ,要先支后改 ,支柱要穿木鞋支設(shè) ,以減少后期支柱的鉆底量。轉(zhuǎn)載機以上的兩排支柱作為人行道 ,寬度為 1. 0m ,兩組柱梁之間的間距為 1. 0m ,最上一排支柱 ,柱檔內(nèi)要加設(shè)密集支柱 ,以防止竄矸。④為減少后維護期間支柱的變形 ,給回撤工作帶來方便 ,沿后維護巷道最上一排支柱 ,每隔 8m 支設(shè)一個木垛加強支護 ,并安專人對后維護巷道進行清理 ,確保巷道高度不低于 1. 6m。發(fā)展前景 隨著煤礦開采年限的減少 ,可采儲量越來越少 ,而隨著深部開拓 ,地質(zhì)條件越來越復(fù)雜 ,三角煤柱也越來越多 ,因此 ,如何在有限的資源下 ,提高煤炭回收率 ,以及解決越來越多的采掘接續(xù)問題 ,將是今后一個很長的話題 ,所以為高檔普采面后維護開采及邊掘邊采技術(shù)提供了一個廣闊的發(fā)展前景 ,具有一定的推廣價值。 結(jié) 論通過這一個學(xué)期的畢業(yè)設(shè)計，我不但鞏固了我以前所學(xué)的知識，而且還學(xué)了不少新的東西。相信在以后的工作中，這一個學(xué)期的設(shè)計生活將成為我寶貴的財富。大學(xué)四年,理論知識學(xué)了不少,但是真正用于實踐的很少。這造成了大多數(shù)大學(xué)生動手能力差，解決實際問題能力差。而大學(xué)也不是為了培養(yǎng)解題的機器。這次畢業(yè)實習(xí)，迫使我們自己動手解決一個個實際問題，是一次很好的理論與實踐相結(jié)合的學(xué)習(xí)的機會。在這當(dāng)中也確實學(xué)到了很多東西。剛開始做得時候，最大的障礙就是不知道從哪里入手。連續(xù)好幾天，沒什么作為。自己有點不知所措。通過王老師和同學(xué)們的幫助及對校園網(wǎng)圖書館里論文的搜索給了我很大啟發(fā)。在轉(zhuǎn)載機總體方案的確定過程中，查閱了相關(guān)的資料，了解了國內(nèi)外轉(zhuǎn)載機的種類和發(fā)展，以及國內(nèi)轉(zhuǎn)載機的發(fā)展前景。通過轉(zhuǎn)載機的總體設(shè)計，了解了關(guān)于轉(zhuǎn)載機名詞的意思，明確了轉(zhuǎn)載機的組成、整機的性能、參數(shù)及各個部分的功能、結(jié)構(gòu)。在對轉(zhuǎn)載機的設(shè)計中，進行了電機和液力耦合器的選型，鏈環(huán)、鏈輪、刮板的選型和尺寸計算，并進行了強度校核。通過機械部分的設(shè)計，系統(tǒng)的回顧了大學(xué)所學(xué)的知識。學(xué)會如何充分利用身邊資源，通過圖書館、因特網(wǎng)查閱所需要的信息，而且學(xué)會了機械設(shè)計的一般步驟，提高了分析問題解決問題的能力。同時養(yǎng)成了吃苦耐勞的精神，學(xué)會了很多東西，更重要的是經(jīng)歷了人生中非常有價值的鍛煉?？偟膩碚f，這次畢業(yè)設(shè)計給我?guī)砹撕艽蟮氖斋@，也為以后的工作打下了一定的基礎(chǔ)。對我們無疑是一次很好的鍛煉。同時，我覺得這不僅是對我四年所學(xué)知識的一種回顧，更是學(xué)會了一種設(shè)計的思路，解決問題的方法，還有就是處事的態(tài)度：不能浮躁，要沉下心，耐心去做。
