It is generally difficult to get analytical solutions of the stochastic differential equation's water quality model. What is more, as to the issue like the initial boundary result of a convection-dispersion equation, it is even more difficult to change the random factors into the uncertainty.

NSFEM法是把Neumann展开式引入以解决矩阵求逆的效率问题，如果对每一次随机抽样，只需形成刚度矩阵，进行前代、回代以及矩阵乘和矩阵加减，而无需矩阵分解，则可大大减少工作量。

The data were applied to simulate the neutron energy spectrum and angular distribution of Lanzhou University 3×10^12 s^(-1) intense neutron generator with 260 keV deuteron beam using MCNP. The interactions of neutron and the materials of neutron generator and laboratary wall were included in this MCNP simulation. The simulation results on the neutron energy spectrum and angular distribution of Lanzhou University 3×10^12 s^(-1) intense neutron generator with 260 keV deuteron beam were presented.

本文采用问卷调查法和个案访谈法对我国贫困农民，城市农民工，城市下岗工和残疾人等四类弱势群体进行抽样研究，运用数理统计法对调查数据进行统计，结合有关专家的建议和近几年来国内有关的文献资料，首先对我国弱势群体的总体体育消费状况进行了分析描述，然后分别对我国四类(弱势农民群体、城市农民工群体、城市下岗工人群体、残疾人群体等)弱势群体的基本特征、体育消费现状、体育消费倾向和体育消费发展趋势等四个方面的相关数据进行比较分析和论证。

The critical loess slopes along the highways were the inputted form of slopes and measured values of cohesions and internal friction angles were the reference values of random variants. Monte-Carlo method was used to choose samples and the formula of the Bishop simplified method was regarded as control equation. The reliabilities of the loess high slopes in three positions of Shaanxi Province were simulated. Failure probability and reliability index were obtained.
