Earthquake Resistant Engineering and Application of Seismic Zonation Map of China

China is a country with high seismieity. It is very important for industry and structure to fortify against earthquakes. In this paper the outline of seismicity in China, the criteria for fortification against earthquakes and the contents of seismic zonation map of China are described. The contents of seismic safety evaluation for major construction projects, such as large dams, large bridges, long distance pipe lines for transporting oil and natural gas, nuclear plants, petrochemical enterprises and so on, are presented. Some geological disasters caused by destructive earthquake, such as earthquake-caused collapse and landslide, liquefaction of saturated soll and earthquake fault and so on, are also presented. Preventive countermeasures for these disasters are discussed.     

加强法制建设促进珠江上游经济环保整体发展

珠江上游南、北盘江流域水土流失严重，生态环境不断恶化，严重影响了该地区经济的可持续发展。法制建设在该地区环境保护中起着至关重要的作用，只有通过法律制度的不断创新和完善，才能为该地区的环境治理提供有效的法律保障，最终达到环境保护与经济发展的和谐统一。     

DEGREE CONDITIONS FOR GRAPHS TO BE FRACTIONAL （a, b, n）-CRITICAL GRAPHS

Let G be a graph, and a and b be integers with a ≤ b. A graph G is called a fraetional （a, b, n）-critical graph if after any n vertices of G are deleted the remaining subgraph has a fractional [a, b]-factor. In this paper two degree conditions for graphs to be fractional （a, b, n）-eritical graphs are presented, and the degree conditions are sharp in some sense.

针对排水管道工程施工中常见的管道位置偏移或积水，管道渗漏水，检查井变形、下沉，构配件质量差，回填土沉陷等质量问题，简要地分析研究了其形成原因，并提出了有效的预防及治理措施。     

现代审计的发展趋势--风险基础审计

风险基础审计是以被审计单位的风险评估为基础，综合分析评价影响被审计单位经济活动的各种因素，并根据量化的风险水平，确定实施审计的范围、重点，从而进行实质性审查的一种审计方法。     

搜寻平面机构中虚约束的拆杆组法

本文根据机构的组成原理,提出一种搜寻机构中虚约束的新方法一拆杆组法,用该方法能方便地判断出机构中所含的虚约束,同时能迅速排除含有特定几何条件而实际上并不存在虚约束的机构.     

异步轧机轧辊稳定性的探讨

本文通过对异步轧制特点的分析,求出中性角及力能参数间的关系,从而导出了不同工作制度下的异步轧机工作辊偏移值的计算公式。本文结论将对改造现有轧机和设计新轧机提供理论依据。     

ρ~0→π~ π~-衰变的么正计算和ρ~0极化插入的虚部

The influence of chronic nicotine treatment on stress-induced gastric ulceration and emptying rate in rats.

Ten-day treatment with nicotine (5, 25 or 50 micrograms/ml drinking water) dose-dependently intensified gastric ulceration induced by cold-restraint, and emptying rate. Stomach contractions produced by graded doses of bethanechol i.v. were elevated further by nicotine treatment. It is suggested that chronic nicotine administration produces hypersensitivity of the gastric muscarinic receptors; stomach hypermotility contributes to the ulcer-worsening action of the alkaloid.
