Historical objectivism is a key question for historiography study . The raise of this question is a progress in the cognition history of human being.

历史客观性问题是史学理论研究的一个核心问题，这个问题的提出是人类认识史上的一个进步。

If plants in the solution oblique triangle usually is unifies with three jiao functions carries on the simplification, perhaps the actual problem, the physical question's form appears, examination mathematics modelling ability.

如在解斜三角形种通常是与三角函数结合起来进行化简，或是实际问题、物理问题的形式出现，考查数学建模能力。

Only when environment problem became a threaten to their living in officialdom will they really pay attention to it....

只有环保问题真正威胁到他们官场生存问题的时候他们才会重视起来。。。

是不是：只有后袋左边有一个带钮扣的袋盖？过日子就是问题叠了问题，你能做的就是迎接这些问题。

Here mainly introduces five natures of the initial value problems, In several aspects summed up as the following : whether there are solutions to the problems, whether the only solution, the existence of solutions interval extent; Initial issues under what conditions have a solution--Cauchy - Piano existence theorem; how the district between the definition of a solution to open up a larger interval up; initial value problems for the sole condition --- Lipschitz conditions; 3、the numerical solution of the initial value problems of Ordinary Differential equations .

在这里主要介绍了初值问题的5个方面的性质，分别在这几个方面中总结了以下内容：初值问题是否有解，解是否惟1，解的存在区间有多大；初值问题在什么条件下有解----柯西-皮亚诺存在定理；怎样把在小区间上有定义的解开拓到较大的区间上去；初值问题解的惟1性条件---李普希茨条件；3：常微分方程初值问题的数值解法。

Based on the principle of optimality,the search problem is then transformed to an equivalent problem of deterministic distributed parameters system,represented by a second order PDE.

采用分析的方法来研究随机运动目标的最优搜索问题，并将原问题转化为由一个二阶偏微分方程所表示的确定性分布参数系统的等价问题，推导出随机运动目标的最优搜索问题的HJB方程，并证明了该方程的解即是所寻求的最优搜索策略。

When QLB was unable to map into OSB directly, IQAS would calculate the semantic similarity between source question of the user and the replaced question.

然后通过对常见问题的语法分析，建立了问题模式库。

I shall find antiquity a rewarding study, if only because, while I am absorbed in it, I shall be able to t urn my eyes from the troubles which for so long have torment ed the modern world, and to write without any of that over-anxious consideration which may well plague a writer on contemporary life, even if it does not lead him to conceal the truth.

现代社会长期以来问题重重，现代史研究者在书写这段历史时忧虑万分，即便他们不会因此而掩盖历史真相，也难免受困于此。而我在潜心于古代研究时，能够不受这些问题的困扰，如果仅仅只有这一点，我也觉得这项工作很有价值了。

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。
