In addition, some experience formulas for them are regressed. The third chapter establishes a unified S-N curve equation to calculate multi-axial fatigue ultimate strength of concrete considering both the effect of confinement and minimum/maximum stress ratio, based on the triaxial fatigue test data in this paper and the test results under uniaxial and biaxial fatigue loading in previous literatures. Moreover, the consistency of calculating condition fatigue ultimate strength with fatigue life distribution and initial ultimate strength distribution is analyzed.

Chapter 3 is the keystone, in which the challenges against the issues of global ecology and environment and the Regime Effects, namely, the ever-establishment of related collection of policies, regulations and laws, have been analyzed. It is involved with the alleviation of anarchical nature of international relations, reinforcement of authority on issues of environment by the international organizations, e.g. UN, the restrictions on governments in which governments take the environment into consideration and the intensification of the international conventions of protecting the environment.
第三章是本文的核心,进一步分析了全球生态环境挑战及其"制度效应"(即不断设立解决相关问题的各种制度、规范和法律):国家间关系中存在的"无政府现象"的减弱,联合国等国际组织和各种环境非政府组织在环境问题上的权威增加,国家受到越来越多条约的约束并且自觉接受生态约束,环境保护的国际习惯也在不断增加。

The apriori and aposteriori H〓-optimal filtering question can be solved directly. L〓 Apriori and aposteriori filtering with an H〓 error bound can be solved by semidefinite programming. Robust H〓 apriori filtering and robust apriori L〓 filtering in discrete-time system are subject to a nonconvex constraint.
对这些滤波问题解法的改进同连续系统下的情况基本类似,对确定性系统的H〓验前滤波和验后滤波,本文解法可直接得出最优滤波问题的解;对H〓约束下的L〓验前滤波及验后滤波,其解可归结为一凸优化问题;但不确定性系统H〓验前滤波和鲁棒L〓验前滤波的LMI解法中有了非凸约束,因此要用迭代法求解。
