The most important exponential function is ex, the inverse of the natural logarithmic function.

最重要的指数函数是ex，即自然对数函数的反数

The Logarithm Process model adapts to describe early failure phase and random failure phase, the Exponential Process model fits for different phase.

其中对数过程模型可用于可修系统使用早中期的情形；指数过程模型可用于描述可修系统各个不同使用阶段的故障统计规律。

It′s found that the GVD-caused chirp in the exponential type of DDF is least likely to be affected by the initial chirp,the GVD-caused chirp in exponential, linear,Logarithm and Guassian types of DDF has the synchronous character of saturation as the nonlinear-effect-caused chirp ,and the two kinds of chirp are found to counteract to balance, which makes the sum chirp tend to be zero.

发现指数型色散缓变光纤中初始啁啾对GVD所致啁啾的影响最小，在指数型、线型、对数型和高斯型色散缓变光纤中GVD所致啁啾具有同非线性效应所致啁啾相似的饱和性，二者相消，使净啁啾趋于零。

Taking WindowsXP,Microsoft EXCEL and VBA as tools,a series of software system on hydrologic frequency analysis which integrated the ability of graph and calculation was developed.And it contained four kinds of frequency distributions:Γ-distribution,extreme value distribution,normal distribution and logarithmic normal distribution.

以Windows XP，Microsoft EXCEL和VBA为开发环境，研制了一套集绘图与计算于一体的水文频率分析软件，其中包含了常用的Γ分布、极值分布、正态分布和对数正态分布4种频率分布线型。

The experimental results show that the distribution founction p of the whole signal group and the different pulse width subsets all fit the lognormal distribution with very high precision in the amplitude's field of definition (V0,VM) under the condition of the big samples, which indicates that the random signal group has the statistical fractal (self-similarity) characteristic.

实验数据表明，在大样本条件下，脉冲信号集合整体及不同脉宽信号子集的p 函数在幅度定义域(V0，VM)内均以很高的精度满足对数正态分布形式，即该随机脉冲信号群具有统计分形特征。

This paper is a continuation of the author's Previous article [ 6 ] on a grap- hical analysis of stationary free oscillation in a nonlinear automatic conttol syetem by tha method of logarithmic characteristics.

本文是作者前一篇论文［6］的续文。在前一篇论文中提出了非线性自动调整系统稳态自振荡的对数分析法。

For example, there is a separate function gammaln just to return the logarithm of the gamma function.

例如，有一个单独的函数gammaln只是返回伽玛函数的对数。

Since the gamma function grows very quickly, it can easily overflow, and so the logarithm of the gamma function is often more useful than the gamma function itself.

由于伽玛函数的生长速度非常快，很容易溢出，所以伽玛函数的对数通常比更有用伽玛函数本身。

The applications of Matlab in engineering calculation of unit operations by exemplifying several typical calculations involved nonlinear equation,interpolation,numerical integration,graphic method and log coordinate drawing are discussed.

以几个典型问题为例，讨论了Matlab在求解非线性方程及方程组、插值法获取物性参数、积分、绘图计算及对数坐标图的绘制等化工原理工程计算中的应用。

In chapter 5, we use MEM algorithm to estimate parameters in Weibull distribution and Lognormal distribution by grouped data and the simulation shows this method is available.

第五章将利用MEM算法对基于分组数据的威布尔分布和对数正态分布进行参数估计，并进行模拟表明此方法的可行性与有效性。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
