It is seen from the fitting results between the frequency distribution curve and the empirical distribution dots that it is proper to use the generalized Pareto distribution to describe the probability distribution of the partial duration series.

从频率分布曲线与经验分布点据拟合的情况看，运用广义Pareto概率分布来描述部分历时序列的概率分布是合适的。

Zakharov empirical formula and DSC curve,as well as,mechanical property and microhardness of this alloy was tested using CMT5105A material test machine and Vickers micro-indenter.The result shows that the phase diagram of Mg-9Gd-3Y-0.6Zn-0.5Zr is feasibility for the...

结果表明：在计算所得的Mg-9Gd-3Y-0.6Zn-0.5Zr相图指导下制定的热处理工艺是正确的；挤压态Mg-9Gd-3Y-0.6Zn-0.5Zr合金的最佳热处理工艺为：200℃时效63 h，抗拉强度σb为=430 MPa，比挤压态提高了30.9%。

Firstly, the paper sets up a rational function model for the long run relationship between economic growth rate and the inflation rate by adding the cross product term of the both into the traditional model of "output-price" Phillips curve. The empirical analysis shows that the product term has substantial impact on the model\'s stability.

第一，本文在传统"产出一物价"型Phillips曲线长期模型中，加入了表现经济增长率与通货膨胀率乘积效应的交叉乘积项，建立了表现二者之间长期关系的有理函数模型。

In this paper,using non-linear equation groups indicating the relations between liquid rocket engine performances and interference factors,the engine performances are simulated by MonteCarlo method' A empirical distribution curve and statistical average value and believalbe range are obtained.

利用液体火箭发动机性能参数和内外干扰因素之间的一组随机非线性方程组，采用Monte－Carlo方法对发动机性能参数进行了模拟。

The empirical curve has since always been the enterprise uses for to analyze the market competition tendency and the development correspondence strategy method, and the experience which accumulates by the enterprise elders takes the main competition weapon, however the science and technology flies suddenly the progress, the enterprise defends stubbornly already has the experience instead to become the barrier which the enterprise develops, therefore in under the dispatch change environment, the experience and the extant channel foundation structure instead becomes the barrier which most difficult to overcome, the success enterprise must establish to the strategy direction sense of smell and continues the vicissitude management system to be able to survive.

一直以来经验曲线是企业用来分析市场竞争趋势及发展对应策略的方法，并以企业长年积累的经验作为主要竞争武器，然而科技的突飞进步，企业固守既有经验反而成为企业发展的障碍，因此在调度变化的环境下，经验及现存通道基础结构反变为最难克服的障碍，成功的企业要建立对策略方向的嗅觉和持续变迁管理体系才能生存。
