缺点

Firstly, according to the difficulties in the optimization of chemical engineering and the intrinsic disadvantage of deterministic optimization algorithms, this work analyzed the importance and advantage of stochastic algorithms, and proposed some important aspects in research on them. Secondly, genetic algorithm was applied to two problems of data driven modeling, one of which was combination problem, the other was mixed integer nonlinear programming. Thirdly, systemic investigations were made on the basic structure, dynamic behavior and modifications of particle swarm optimization. Lastly, two kinds of proposed PSO algorithms were applied on calculation of phase equilibrium, which is nonconvex optimization.

本文首先根据化工优化中存在的困难和确定性优化算法内在的缺点，分析了随机优化算法的重要性，并提出研究随机优化算法应注意的问题；其次，将遗传算法应用于两个数据驱动建模问题，一为组合优化问题，一为混合整数优化问题；再次，从粒子群优化算法的基本结构、运动行为、改进方法做了系统的研究：最后，将提出的两种改进粒子群优化算法应用于相平衡计算问题，为非凸全局优化问题。

I'm sure we all have some developmental areas we should be aware of, but I must say, as I

我确信我们都有需要再发展的地方，但当我很清楚我的缺点时，我必须要

Many shortcomings are proved to be existent in the current cushion design, among which there are over dependence on deviser's experience, requirement for devastating tests , great waste of cushioning material and product, excess packing.

其设计方式存在过程复杂、较大程度地依赖设计人员的自身经验、以及需要破坏性试验等缺点，造成产品和缓冲材料的浪费，也容易造成过包装，在一定程度上制约了运输包装设计的发展。

This dissertation has conducted some information superiority oriented research focusing on some key technologies such as information acquiring, object recognition, situation assessment, threat assessment, target assignment, effectiveness evaluation of C~4ISR system, effectiveness evaluation of NCW in cognitive domain and so on. The main research and devotement of this dissertation are listed as follows: 1. Based on the analysis of physical meaning and campaign course of Lanchester linear law, we proposed a model reflecting the impact of surveillance and reconnaissance on force attrition. The model also discussed the effect of asymmetry information on the outcome of the battle, and conquered the disadvantage of Lanchester equation in modeling C~4ISR system.

本文面向信息优势对C~4ISR系统的信息获取、目标识别、态势评估、威胁估计、武器分配、效能评价以及网络中心战等关键技术进行深入研究，取得了一些创新性成果：(1)通过对Lanchester线性率中各参数物理意义及作战过程的分析，建立了反映侦察和监视效果的兵力消耗过程模型，并引入博弈论分析了战场上信息的不对称对交战结果的影响，克服了描述C~4ISR系统的Lanchester方程没有考虑作战单元、对手和环境间的动态交互以及数学结构简单的缺点。

What we need to do most is to work on our di sadvantages and shortcomings.

我们最需要做的，是克服缺点和改进不足之处。

On the other hand, in some areas in medicine, it may be sufficient to maintain high image quality only in ROI, i.e., in diagnostically important regions.

针对系数提升ROI算法的固有缺点，提出了一种基于率失真优化截取内嵌码块编码算法的医疗图像矩形感兴趣区域编码方法。

First, he speaks a dialect which make others can't understand what he said. It is his big disadvantage .

第一，他说的方言让人很难明白他说什么，这是他的一大缺点。

It is also useful for some special types of the cataract and as an alternative method for the capsulorhexis failure cases.The main disadvantage is the fragile capsule edge following the diathermy capsulotomy.

对于初学者及某些特殊类型的白内障，电子环形撕囊简单易操作，同时对于手工撕囊失败的病例是一种有效的补救方法，但有撕囊口易撕裂的缺点。

Instead, he remained confined to dictatorial rule in Taiwan; despite his regime's shortcomings, it becameed in 1975 his son Chiang Ching-kuo ruled, less dictatorially.

不论该统治的缺点，台湾成为贸易大国，特别是在电脑科技。1975年蒋介石死后由他儿子蒋经国执政，少了些独裁色彩。

Surface blending in terms of geometric continuous is more practical and welcome with view of geometric interpretation which is different to the traditional differential method based on algebra.

几何连续是对参数曲面中参数连续度量进一步深刻的认识和研究。它是可微性的代数概念的几何抽象，克服了参数连续对曲面苛刻，高阶及结果失真等缺点。

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。
