What Are Behind The Electric Car Heat?

Is the world's auto industry going to change greatly in the future 3-5 years so that ICEs will fade out?Will this electric car heat repeat itselfjust like it did in the history? The Chinese government issued pro- grams in Jan 2009 to cheer up the auto industrv.The plans include enacting new energy vehicle strategy,industrializing     

An interview with WAN Gang——Chief Scientist of 863 Special Project for Electric Vehicle

Reporter: Will you please give an account of the development of electric vehicles in the world? Wan: The history of electric vehicle is almost the same as that of ICE vehicles. The electric vehicles have many advantages. Its drive system is of zero torque so that it creates more torsional force. Why is the electric vehicle developed slowly? The main     

Scientific and Technological Innovation and Operation related Issues for Island Tunnel of Hong Kong Zhuhai Macao Fixed Link Project（港珠澳大桥岛隧工程建设的科技创新和 运营后应关注的若干问题）

The author explains why a giant undersea immersed tube tunnel was selected for the sea area of the main channel of the east side of the Hong Kong Zhuhai Macao Fixed Link Project, instead of employing a bridge or shield tunnel; and summarizes several domestic and international leading innovative technologies applied in the island tunnel construction of the Hong Kong Zhuhai Macao Fixed Link Project, including the use of huge self stabilized steel cylinders as retaining structure of foundation pits for constructing the artificial islands, the large area and ultra deep "sand compaction pile (SCP) composite foundation" reinforcement technology, "semi rigid segment joints", "sandwich" steel RC combined inverted trapezoid closure joints, and crack control and anti corrosion/durability design for RC tube structure. All these technologies reflect Chinese wisdom and Chinese speed. The author also points out some technical issues to which attention should be paid after the immersed tube tunnel of the project is put into operation: （1） Will the post construction settlement and differential settlement of the immersed tube tunnel further develop after the project is open to traffic? How much is the final convergence value? If it exceeds the limit, what control measures should be taken?（2） How to deal with the issue that the joints of large/small elements or segments are open? How to ensure that all the large and small joints between segments of the tube are "watertight"? Furthermore, the author presents some suggestions and control measures: （1） For excessive post construction settlement (especially differential settlement) spotted on large joints, it is suggested to incorporate "micro disturbance grouting" for post treatment. （2） If a joint opens under the excessive positive bending moment at the floor slab, it is believed that the open joint on the floor slab can be closed again by cutting off some prestressed tendons in the roof slab of the segment to reduce the positive bending moment of the section.

Reporter: Please say something about the entire structure of Chinese auto industry after the WTO entry, and what do you think it should do to cope with the new challenges? Zhang: This is an old question we have talked about for years. Now China is already an official member of the WTO and what we discussed before should become specific policies or measures.

A review and evaluation of the 1994-based Industrial Policy for the Auto Industry

The formation of the 1994-based Industrial Policy for the Auto Industry took the form of broadly soliciting comments from various sources full coordination and consultancy among government departments; hearing comments from experts; taking advice from companies in the auto industry. However, as it was a result of discussions within government and inside the industry, it mainly reflected the ideas of the government departments and manufacturers as well as the interests of auto producers. From the view point of the making of governmental public policies, it lacked publicity, transparency and broadness, together with a low degree of public involvement.

The Investment and Competitive Strategies of Auto Industrial Powers in China

1 The Investment Situation of Auto Industrial Powers in China Chinese auto industry has made rapid progress after development of 50 years. However it is still at the infant stage. The government has to protect it by means of long-term, rigorous tariff and non-tariff devices. But the U.S., Japan and other European countries have made investment into Chinese auto industry, because it's incontrovertible that China is the most potential market in the world.
