Vehicle Dependability Index Study(VDI) This study provides a problem measurement and diagnostic system similar to that of our Initial Quality Study (IQS). VDI is desired to capture information on the quality problems of two-to four-year old vehicles. While it closely follows the IQS design, VDI replaces problems that occur dung production and shipment, such as dents and dings, with longer term problems such as rust and corrosion.

A Magic Book Out of Magic Language

Harry Potter booksare great successes, enjoyed by readers' all over the world. Harry Potter and the Philosopher's Stone is the debut of the sequel books, which is about magic and the magical life a little boy-Harry Potter, a born wizard. People are always curious and eager to discover the secrets of magic, to meet the end of the heroes' fates, but not many of them pay attention to the book's language. Actually, I think it is the skillful use and application of language that make the book outstanding. Therefore, this paper mainly discussesthe language features of Harry Potter and Philosopher's Stone from these four as-pects: speech sounds, choice of vocabulary, sentence structures and figures of speech, aiming at exploring and revealing the charmsof the magic book.     

锦屏二级水电站深埋特大引水隧洞关键技术

Seven tunnels across Jinping Mountain are arranged for Jinping Ⅱ Hydropower Station, with a total length of about 120 km. Among them, four headrace tunnels have a length of 16.67 km, an excavated diameter of 12.4-14.6 m, and a cover depth of 1 500-2 000 m in general. The maximum cover depth is 2 525 m, and the maximum external water pressure is more than 10 MPa. The tunnels are featured by great length, great depth and large diameter. It is the largest and most difficult among the underground tunnel groups built or under construction in China and even the world. With complex hydrogeological conditions and special topographical conditions along the tunnels, many challenging problems, such as rock burst under high in situ stresses, groundwater inrush in karst strata and failure of loading bearing structure, were encountered during construction. A great amount of groundbreaking studies were carried out regarding these problems. The key technical problems during construction of extremely large and deep tunnels were solved successfully. Safe and rapid tunnel construction and stable operation were achieved. The hydropower station started operation in 2014 and has been in a safe and stable operation state. The successful construction of headrace tunnels of Jinping Ⅱ Hydropower Station can provide some experiences and reference for deep tunnel projects in the world.

SITUATION OF CHINESE INDUSTRIES AND ITS RELATION WITH AUTO INDUSTRY

Editor's Note:The author took part in the writing of "Economical White Paper of 1993-1994". Some important viewpoints about the development situation of Chinese industries were suggested in that paper. The author thought that these viewpoints can inspire us deeply to grasp the trend of Chinese auto industry in 1994. So,some views on Chinese auto industry of 1994 are put forward based upon these important viewpoints by the author.     

Application of ethanol vehicles in China

I. Background Alternatives to petroleum as an energy source have been an important topic for countries all over the world. The aims are to solve the problems of a lack of oils and protection of the environmental, to reduce as far as possible over-dependence on petrol and to ensure ensure energy safety commensurate with the sustainable development of the auto industry. Since the 1940's, countries have invested large sums of money in     

The Status and Trend of Chinese Auto EC

As a new information industry, E-commerce is becoming a new growth point of economy, and changing the development of traditional industries such as the auto industry. E-commerce would ultimately bring it profound changes. Therefore, many countries are employing E-commerce to impel the development of the auto industry rapidly. As the final large market, China has to keep up with the trend of global auto development. If we did not explore and establish E-commerce actively, with WTO coming, we

Study of Collaborative Management of Intelligent Highway Tunnel（智慧公路隧道协同管理研究）

Aiming to solve the problems of collaborative management of intelligent tunnel and tunnel management under different traffic conditions, the tunnel is regarded as a part of highway, and five features of the intelligence are proposed from the definition of intelligence. In order to realize a collaborative management of intelligent highway tunnel, the spatial extent of tunnel is defined at first. Then, a collaborative management road topology based on road critical nodes is proposed; and a holographic collaborative control information system based on tunnel structure, facilities, vehicle, operation, management, and environment is established. Finally, collaborative control of people, cars, roads and environment could be realized, so as to improve the management level of the intelligent highway tunnels.

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.     

Key Design Technologies for Cutter Replacing of Super large  Slurry Shield under Atmaspheric condition: Case Studies of Shantou Gulf Tunnel and Shenzhen Chunfeng Tunnel（超大直径泥水盾构常压换刀设计关键技术——以汕头海湾隧道及深圳春风隧道为例）

By analyzing the application cases of super large diameter shield machine in the world and taking China Shantou Gulf Tunnel and Shenzhen Chunfeng Tunnel construction for examples, the problems encountered in the research and development and construction are proposed and the key technologies to solve a series of problems, such as cutterhead maintenance and cutter changing technology under high soil and water pressure, boring in long fractured zone, are explored. More specifically, the technologies mainly involve cutterhead design, atmospheric cutter changing, main drive with telescopic and swinging function, reliable sealing system, anti blockage technique by applying double crushers, which are of great significance to the development and application of super large diameter shield machine.

Call for Papers Feature Topic on Robust and Certifiable Perception System for Intelligent Vehicles

正The perception system is one of the most important parts of intelligent vehicles and has developed rapidly in recent years. Accuracy, efficiency, and robustness of perception algorithms like object detection and scene parsing have been greatly improved. However, the correctness and stability of the perception system in changeable and unseen environment is still not well-solved. The certifiable perception system is a feasible method that can provide formal performance guarantees and real-time assessment of the correctness.
