舰船纵向弯曲强度可靠性分析的动态模型

在多种载荷联合作用下舰船总纵强度可靠性分析计算中，考虑时间因素，用随机过程代替随机变量，即以动态模型与第二水平法相结合求解可靠性指数，分析表明，此方法较静态模型能更好地反映实际情况，对在役或老龄舰船尤为适用。     

Study of Venture Capitalist Compensation Structure Based on Reputation Model

The development of venture capital has drawn much attention, and many qualitative analysis and discussions have been proposed. A quantitative model is proposed based upon Reputation Model. The present compensation structure of U. S. venture capital limited partnerships is analyzed and a kind of new compensation structure is proposed. The relations between the venture capitalist' s effort level and the two compensation structures are given . The comparison of analytical results proves that the present compensation structure in U.S. may not be the best choice, and that the proposed one can give a better motivation for venture capitalist's management action.
