riks怎么记

Based on NFEM, a modified RIKS algorithm is used in this paper to study the ultimate strength of a series of structures of the Semi-submersible platform. At the same time, the key techniques of the global ultimate strength of the semi-submersible platform also have been investigated.

本文基于非线性有限元法，采用修正的弧长法，对一系列平台结构进行极限强度研究，同时也对半潜式平台整体极限强度的关键技术进行了研究。

Then, in the original state without damage, the impacts of parameters of the ribs height, thickness, and interfacial strength on the buckling load and ultimate strength of stiffened composite plates are discussed using the RIKS method.

然后在原始无损伤状态下，通过引入屈曲模态，探讨了筋条高度、宽度参数等对复合材料加筋板屈曲载荷和极限强度的影响。

The risks of the rural policy finance are bigger and bigger and the riks managements of aid the poor funds are much more difficult.

农村政策性金融的风险越来越大，特别是扶贫资金的风险管理难度更大。
