Ambition is the determination and courage to strive to do something。October 22, 2018，General Secretary Xi Jinping emphasized when inspecting Gree Electric Company: "The core of the manufacturing industry is innovation，Just master key core technology，It must be more struggling by self -reliance，Strive by independent innovation，I hope all companies will fight in this direction。We want to have independent innovation bones and ambitions，Accelerate the enhancement of independent innovation ability and strength。"as a high -speed railway for China's" golden business card "，It is China successfully innovated under technological backwardness、Typical representative of the leading technology。The key to technological innovation，It is the ambition of Chinese science and technology workers。

2004，China has decided to introduce high -speed rail through technology，At this time, bet365 Play online games China's high -speed rail technology has fallen for half a century。，Chinese ambitions high，Determine to create your own brand，Master the core technology，Realizing flying from technology to independent innovation，It is mainly based on three aspects。

First，Is creating your own brand、determination to master core technology。Thought is the pioneer of action，The target is a guide for action。China is in the process of introducing foreign high -speed railway technology，Determined to create your own brand、Master the high goal of core technology。The brand's brand (Brand) is an identification logo，It is the core value embodiment of the products owned by enterprises and enterprises。2004，The bidding manual bet365 live casino games of the high -speed trains and EMU announced by the Ministry of Railways proposes "Introduction to Advanced Technology，Joint design and production，Create a Chinese brand "overall requirements。This requirement includes three layers: one，Introduction is advanced technology，"Requires foreign parties to fully transfer advanced technology，Especially system integration、AC core technologies such as exchange drive ";，Joint design，That is to integrate Chinese personnel to participate in technical design together，Requirement "Foreign partners provide technical services and training for domestic enterprises，Improve domestic enterprise design、Technical level of manufacturing and quality management personnel ";，Create a Chinese brand，"Adhere to domestic manufacturing，All Chinese brands "。Under this goal guidance，China has created a CRH high -speed train brand。Later, CRH became a new trunk line with Japan、German ice、French TGV's famous world -class brand。Especially after the birth of the Chinese Standard EMU，China’s high -speed trains have completely owned independent intellectual property，China’s high -speed trains have completely owned independent intellectual property。

Core technology is the brand's hard core decisive factor，The decisive factor that the product stands in the unbeaten place in the competition。bet365 Play online games China's high -speed rail technology introduces the road with marketing technology，But the market cannot buy core technology。Even so，China is also determined to buy high -speed rail technology instead of only high -speed rail -related equipment，Emphasize "introduction of advanced technology"，"Combination of technical and trade、The way of independent innovation "。So，In the technical transfer link，How to learn from foreign bet365 best casino games train manufacturing technology and realize independent innovation，It is a huge challenge facing China。

In order to learn technology，Chinese car company selection technical backbone to sign a foreign company system learning technology。Tangshan Bus Factory (hereinafter referred to as "Tangke") sent hundreds of people to Siemens for training。From technical design to manufacturing technology，Scholars are arranged in each link。After returning to China，These technical backbones are produced by vehicle production under the guidance of foreign experts。Chinese car companies have determined the learning route of "rigid -solidification -optimization"，It is significant。The technical staff of Qingdao Sifang Vehicle Factory (hereinafter referred to as "Sifang") said，Learning is like "Breaking the Floor Window Paper"，greatly broaden the ideas and vision of Chinese technicians: "This is the foreign manufacturing system、The research and development system learned。From this，The appearance of our entire factory has changed dramatically。This process builds the manufacturing of modern enterprises、Test、Management System and Concept，The concept of traditional locomotives and vehicles is very different。"" After "drawing gourds according to the same"，Cixedly the things learned。"Tangke" Wu Kechao said，By learning "Putting the production technology of German locomotive (production、Design、The whole process)，Including the solidification of the quality management system，Form a habit，Become our own things。I think this is the essence of our successful absorption "。

Next，It is the will to realize the will from technology introduction to independent innovation。Relying on independent innovation is the most important experience of technical personnel in bet365 Play online games China's high -speed rail technology development。According to Liang Shulin, the deputy president of the Changchun Bus Factory at the time, said: "From digestion、From this stage of absorption，Everyone thinks that the core technology does not transfer，Foreigners will not give us core technology，Just tell you what it is，He will not tell you why this is like this。So this process is very difficult。We are designers for research and development，Must know why this is like this。"So，To master the core technology，The managers and technicians of Chinese car companies work particularly efforts。One is to learn carefully。According to the "Tangke" employee who goes to Germany, it is said，Training "Just tell some theories，Wait until the actual operation，Look at it with your own heart "。"When each of us go out，All prepared a study log，Daily learning content，Record all the places you need to see。"Back to the residence after get off work，After all the contents of the day learning during the day are sorted out，Record the problem that is not understood，Please ask again the next day。"Tang Ke" sent personnel to establish deep teacher -student friendship with Siemens's technical experts，The teaching of the experts is trying to do our best，Students learn more solidly。The second is to ask for the initiative。As Liang Shulin said，Foreign car companies will not take the initiative to tell Chinese technicians why，But if China asked questions during the learning process，Generally answers。He raised more than a thousand questions about the technical experts of Siemens about the steering rack of the third car at the time，Ask them to answer。Three is my own realization。When the "Tangke" produces the first train for debugging，"All technicians are staring bet365 live casino games at the car every day，One problem，Everyone concentrated，Develop brainstorm，Go to study、Analysis and simulation "。

again，Is the courage that is impossible to change。Innovation is to start to unknown fields，Get new breakthroughs and success。When I first learned high -speed rail technology in China，Foreign experts、Even some Chinese technology workers in China are suspicious of whether they can successfully learn this technology，Don’t be technological innovation。But Chinese technology workers，But with a kind of courage that is impossible for possible，Into the high -speed rail technology innovation。

The precipitation of existing knowledge and experience of individuals is the basis of innovation，But it is also easy to become the restraint of innovation。So，Innovation must first challenge the existing cognition。Challenge has become a consensus social cognition to a certain extent，More courageous support。Compared with the Puchai Railway，Many problems have changed fundamentally，But at that time, the Chinese science and technology workers existing cognition，Most of them are still in the Puchai Railway stage。Professor Wang Ping of Southwest Jiaotong University tells that when he develops high -speed railway roads，Facing similar problems: "First of all, we must change the concept of many people。The change of some concepts for many people，Especially for some older people, it is very difficult。"For example, after the high -speed train enters the road fork，generates left and right swing phenomena。Wang Ping believes that it is caused by the rolling creep，But this analysis does not get the recognition of the old expert of Daocha。Wang Ping had to go to the scene again and again，Pointing at the light band of the Dao fork's rail，Prove to the old experts that this is the Bet365 app download result of the role of creep，"Slowly，Old experts only change their views。So this process is difficult，Because of the older generation of experts，Some accumulation of no dynamic theory，No mastering the simulation tool，No advanced research methods，Still staying on the basis of quasi -static or sports, understand，So I can't understand the problem where the problem is "。So，To convince these old experts，Need to have the courage like a newborn calf。

High -speed rail technology worker，Not only must you challenge the restraint of the existing cognitive，It is also necessary to challenge the "impossible" concept of innovators' own thoughts，Stiring the courage that is impossible to change。Ding San San, the chief engineer of the Sifang, recalled that they felt deeply when they remembered their leap from CRH380A to Fuxing EMU: "In fact, found in this round of innovation，Many things can be done。I didn't do what I did，Do a way to do it，Put a more advanced method and concept to do，Can be done。"" CRH380A was produced at that time，Many designers feel that their responsible part has reached the limit，When it is developed, it is considered that it is impossible to improve technology。Fuxing Number and CRH380A are the same length，"The section of the Fuxing" is larger than the CRH380A，However, it is required to further reduce the resistance，Reduce noise "，At that time, it was required to reduce the pneumatic resistance by more than 10%，"Everyone thinks that it is a joke again，It is impossible to achieve "。But，After in -depth research，"Decomposure to each item、Each indicator parameter、Each design，Step step -by -step split indicator "，Perform refined control，"The pneumatic resistance is increasing to the body，Ten more than ten percent than the original bet365 live casino games "，It will not be possible to be possible。

High -speed railway technology is a complex system engineering，Its innovation is a full of thorns、Process full of difficult and dangerous obstacles。The ambition of Chinese science and technology workers，Guide、Encourage Chinese science and technology workers to develop innovation，Going out of a technical leader。
