Chapter 4 puts up the basic theory of non-linear finite element calculation methods and deduces calculation iterative formula and relevant accelerating iterative format. In the calculation of non-linear finite element, yielding element calculation is a difficult problem,"fictitious elastic stress" methods propounded in this paper puts the axe in the helve.

第四章提出了非线性随机有限元法的基本理论，并推导了计算迭代公式，为加快计算速度，提出了相应的加速迭代格式，对于基于非线性随机有限元的可靠度计算中，屈服单元的计算方法是一个难题，本文提出了"虚拟弹性应力"法，较好的解决这个难点。

Based on the review of the successive four assessment reports of the IPCC WGII on climate change impacts on streamflow from 1990 to 2007, it is summarized that the First and Second Assessment Reports were regarded as the first generation studies, featuring the impacts of mean climate change on streamflow and the adaptation to it, while the Third and Forth (AR4) Assessment Reports as second generation studies, emphasizing the impacts of anthropogenically forced and natural climate changes on streamflow and the adaptation to them. The progresses and issues in the research methodologies of the impacts of climate change on hydrology and water resources are analyzed.
