The first part gives a constraint on partition, in such a way that a cubic spline of interpolation under such a constraint of partition uniformly converges to a continuous function.

第一部分给出分划的一种限制，使在此限制下三次插值样条一致收敛于连续函数。

Because of the MA noise model part, the criterion function for ARMAX model identification is not always unimodal and an optimization based algorithm has a potential risk to be stuck at a local minimum.

在 ARMAX模型的辨识中，由于滑动平均噪音模型部分的存在，用以估计 ARMAX模型参数的误差函数不再是单峰的，因而常用的基于最优化的估计算法有被陷入局部最小点的危险。

The part of calculus that deals with the variation of a function with respect to changes in the independent variable by means of the concepts of derivative and differential.

In the academic circle, it is usually hypothesized as a single distribution function for the duration model while applying to Schmidt and Witte's (1989) split population duration model.

学界应用Schmidt and Witte (1989)的区分母体持续时间模型时，通常在「持续时间」的部分，假设它为单一分配函数。

Based on the extended Huygens-Fresnel principle and the quadratic approximation of phase structure function, we have derived the analyticl expression of the spatial degree of coherence for partially coherent flattened beams propagating through the slant turbulent atmosphere with the help of tensor integral, then analyzed the effects of different zenith angle, propagation distance, coherence of source and outer scale of turbulence on the spatial degree of coherence on the receiver.

基于广义惠更斯-菲涅耳原理和相位结构函数的平方近似，运用张量积分的方法导出了部分相干平顶光束通过斜程湍流大气传输后接收面光束空间相干度的解析表达式，分析了不同天顶角、传输距离、光源相干性以及湍流外尺度对接收面光束空间相干度的影响。

It consists of three parts firstly,a large number of meshing data were measured out through three dismountable teeth installed along the radial direction of rigid wheel under loading status,secondly,the experimental curves of tangential force t and of radial force r inside meshing zone were gained by means of method of mathematica...

包括三部分：首先，在载荷状态下，通过安装在刚轮径向方向上三个可装、拆的活齿，测得大量的啮合数据；其次，通过数学统计方法获得啮合区内切向力Ft和径向力Fr的实验曲线；最后，应用函数逼近法获得载荷区内载荷分布方程

Most of the literature on bank runs takes the asset side of the bank activities as given and assumes that the bank's returns are determined by an exogenously given production function.

大多数有关银行挤兑的文献将银行经营的资产部分作为给定的，并假定银行收益是由外生给定的生产函数决定的。

We analyse the probability of success in deception by malicious groups of receivers, discuss the threshould schemes with limited the number of malicious receivers, give the calculation formule of probability of successful attacks in any transmitted information, and information - theoretic lower bounds,show the size of the secret key space for each participation under the securiey level, provide the construction about the authentication schemes.

第三部分提出了动态会议认证系统，利用动态会议系统的特点，引入验证密钥集，我们运用熵函数，交互信息量及概率分布等方法，对限制内部欺骗者个数的情况进行了分析，得出了欺骗者对系统实施各种攻击成功概率的计算公式及信息论下界，说明了系统在某一安全水平下，各用户应掌握的密钥量。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
