平静务实看待中国经济“超日”

根据日本内阁府8月、6日所公布的数字显示,今年第二季度日本实际国内生产总值按美元计算为12，880亿，环比增长0．1％,按年率计算增长0．4％。与较早前中国所公布的今年上半年经济数据，第二季度GDP按美元计为13，390亿,以单季度比较,中国已超越日本，成为全球第二大经济体。

Protection of Historical Buildings in Metro Line Construction: A Case Study in Shanghai,China

This research presents a holistic approach to the protection of historical building group adjacent to metro line construction, in which health investigation, protection criterion determining, numerical simulation analyses, corresponding protection measures and field monitoring analyses are incorporated as main procedures. A case relating to the conservation of a seven-storey brick-wood pagoda, Longhua Pagoda, adjacent to the construction of Shanghai Metro Lines 11 and 12 in China, is presented. A reasonable protection criterion is determined rationally by means of numerical simulation based on the health investigation results combined with related standards, which can help to achieve a fine balance between system safety and cost constraints in protection measures determining. A full numerical model is developed to analyze the effect of dewatering, excavation, tunneling, and shield departure/reception, and corresponding measures are adopted to ensure the safety of the pagoda. Especially a brand new method, steel jacket method, is introduced in detail, which has a good performance on decreasing the amount of dewatering and maintaining a stable working face. Results demonstrate the application potential of the proposed approach, as well as its feasibility. The proposed approach can be used in the industry by practitioners to provide positive guidelines on the conservation of historical building group against metro line constructions. The reliable and detailed data in this case can also provide verification for subsequent research.     

奥迪车无法起动

一辆05款奥迪A6L2．0TFSI轿车,累计行驶7000km,出现发动机无法起动的故障。把该车拖回公司后,连接VAS5051进行检测,结果无故障代码显示。接通点火开关起动发动机试车,毫无着火征兆。分析发动机起动不着的原因有以下3种：一是无电;二是无油;三是无信号输入或输出。
