For the reliability analysis of implicit limit state function, finite element analysis is a time-consuming process, and it impedes the application of normal importance sampling approach.

对于含有隐式极限状态方程的问题，重要抽样方法将大部分的计算时间用于结构有限元分析，这使得重要抽样的计算效率被大大降低了。

Cleanness is rural, eradicate fireweed, reduce insect of concealed disease host, copula and pathogeny, be helpful for preventing this disease popularity.

2清洁田园，铲除杂草，减少隐症寄主。介体昆虫和病源，有利于防止该病流行。

Robust design objective is always structural response′s first derivative, constraint functions are nonlinear functi...

鲁棒设计目标函数为结构响应的一阶导数，约束函数也是非线性隐函数，因此是多变量的非线性优化问题。

For in this world, time flows not evenly but fitfully and, as consequence, people receive fitful glimpses of the future.

在这个世界里，时间不是平顺地流过而是忽进忽止。因此，未来也乍隐乍现。

The new method employs Viterbi algorithm and HMM parameters to produce the best state sequence and then to warp the time within the same state segment using function approximation technique and intersection technique. So a fixed dimensional feature vector can be got. It is then sent to the RBF neural network.

新方法首先利用隐马尔可夫模型参数和Viterbi算法产生语音信号的最佳时间序列，然后利用函数逼近和插值的方法进行时间规正，组成等维的语音识别特征；最后送径向基函数神经网络进行识别。

This article discusses four factors of inditing exordium of Tolstoy s works: a the focusing point of implying the main line of a novel; b the entering point of accepting the historical background; c the flashing point of exposing the author s inclination ; d starting point of identifying the artistic style.

本篇着重研究了托尔斯泰开端创作的四个方面：一、隐示作品主线的聚焦点；二、接纳历史背景的切入口；三、透露作者倾向的闪光点；四、确定艺术风格的起程点。

He was conscious of, but could not apprehend, their wayward and flickering existence.

他虽然不能领悟，但却意识到他们变幻莫测，忽隐忽现的存在。
