Most of them rely on the central limit theorem, that states that the mean of N independent realizations of a random variable with mean u and variance d^2 approaches a normal distribution with mean u and variance d^2/N .

在蒙特卡罗评估框架内大量的各种选择性算法已经被推出，他们中的大部分依赖于中心极限定理，一个均值为U方差为D^2的随机变量的N次独立实现的平均值接近于一个均值为U方差为D^2/N的正态分布。

Poisson's equation:In space where the source density is ρ, the Laplacian of a : potential U is 2 U = 4πρK, where is the operator del and K is a constant (gravitational constant in case of mass and gravitational potential).

泊松方程：在源密度为ρ的空间中，位场 U 的拉普拉斯算子为： U = 4πρK，。在米-千克其中为 del 算子，K 为常数(质量的万有引力常数和重力势)秒单位制中应去掉常数 4π。

Of course, you can not frequently adopted approach to cleaning up formatting U disk, this disk will also affect the life of U.

Firstly, the natural frequencies and normal mode shapes of the fluid-conveying pipe with zero fluid velocity (i.e. U=0) were determined with the transfer matrix method. Next, these natural frequencies and normal mode shapes were used to derive the equation of motion for the fluid-conveying pipe with fluid velocity U.neq.0 by using the expansion theorem. Finally, the free and forced vibration responses of the pipe with flowing fluid were obtained by means of the Jacobi method and the Newmark direct integration method.

首先吾人使用转移矩阵法来求取一流速等於零(即U=0)、跨距数为N之流体输送管的自然频率及其所对应之正规化振态，然后利用振态重叠法原理来推导流速不等於零(即U.neq.0)时，整个流体输送管在外力作用下的运动方程式，最后再以Jacobi法及Newmark直接积分法来计算该水平流体输送管的自然频率及强迫振动反应。

Results Avermectine had no influence on body weight and cerebellum body ratio. The activities of LDH, GS, CK and CaN in 5.0mg/kg group were 15.508±0.084, 299.849±33.563 U/grot, 7.635±0.377 U/ml, 0.699±0.043 Umolpi/mgprot/hour, respectively at the end of treatment. Compared with the control group, the activities of GS and CK were increased and the activity of CaN was decreased.
