数值分析

In order to study the resistance to overturning of loess slop, numerical simulation be needed.

为了研究整个滑坡体的稳定性，需要对黄土滑坡整体进行数值分析。

A particularly investigation is carried out to the observibility of in-flight alignment using numerical simulation when the aircraft performs four kinds of basic maneuvre, namely linear acceleration, yawing, pitching and rolling. The thesis summarizes the two kinds of maneuvre. Simulation results show that the precision of transform alignment reach 5 minutes in 10 seconds if the aircraft performs two well-defined maneuvres.

首先本文采用数值分析的方法研究了直线运动、航向角运动、俯仰角运动和横滚角运动对传递对准系统可观性的影响规律；再结合飞机的实际运动，给出了空空导弹传递对准时的飞机飞行轨迹；"蛇形"飞行轨迹和摇摆运动飞行轨迹，仿真结果表明：按这两条飞行轨迹机动，在10s内传递对准精度可达到5′以下。

Numerical examples show that the method works effectively.关键词: Cauchy problem for Laplace equation, Ill-posed problem, Mollification method.

遗憾的是审稿人对该类问题的理论及数值分析方面的研究现状了解甚少，因而难以给出进一步的评价，但审稿人认为在理论上这是一个很好的结果。

Then the explicit expression of it under exponential claims and the differential equation are obtained.Thus we discuss the effects of credit and debit interests on it through data analysis. Through the research of the mean,the moment generating function and the higher moments of discounted aggregate dividend payments,we discuss the optimal dividend payments problems.

而对于Gerber-Shiu函数的研究，则是通过随机过程及随机微分方程的知识得到它满足的积分-微分方程及边值问题，然后得到了它在指数索赔下的明确表达式以及Erlang(2)索赔下满足的微分方程，并通过数值分析得到贷款利息及存款利息对它的影响。

Numerical migration for typical models show that, in contrast to ray method, prestack wave motion migration can correctly image inhomogeneous media, and suppress multiple reflection wave effectively.

典型的介质模型数值分析表明，与射线方法相比，接收函数的波动方程叠前偏移能对横向非均匀介质准确成像，不仅有较高的分辨率，而且对多次波有较明显的压制作用。

This paper mainly experiment research and numerical analyzed the submunition ballistic trajectory condition of hard structure munition.

本文主要对攻坚弹药子弹弹道环境进行了初步的试验研究和数值分析。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
