For a class of bilevel multi-objective decision,this paper converts it into the problem of equivalent single-level multi-objective decision,then makes use of the inversion property of the genetic algorithm with the ergodic property of the chaos optimization method.Combined with exact non-differentiable penalty function,a new chaos genetic optimization algorithm is presented.

针对求解一类二层多目标决策问题，首先将其转化为等价的单目标决策问题，然后利用遗传算法优化的反演性和混沌优化方法的遍历性，并结合精确不可微罚函数求解非线性约束优化问题，提出了求解此类问题的混沌遗传算法。

A class of bilevel multi-objective programming was converted into the problem of equivalent single-level multi-objective programming. Then a new chaos genetic optimization algorithm was presented by using the inversion property of genetic algorithm and the ergodic property of chaos optimization method and combining with the exact l_1 penalty function.

针对求解一类二层多目标规划问题，首先将其转化为等价的单目标规划问题，然后利用遗传算法优化的反演性和混沌优化方法的遍历性，并结合精确罚函数求解非线性约束优化问题，提出了求解此类问题的混沌遗传算法。

Furthermore, the situation of the targets and imaging devices considering noise is studied. The recurrence formula of parameter estimation and the steady variance of estimation error are given.

进一步研究了目标受到干扰及成像设备存在噪声情况下的目标运动参数的估计问题，得到了参数估计的递推公式，并给出了估计误差稳态方差的范围。

The essential prerequisite for convergence of any optimization algorithm is that the objective function to be solved has only one minimum in its definition domain, that is, it is a single valley one.

而各种最优化算法收敛的前提条件是所要搜索的目标函数在其定义域上只有一个极小值，即目标函数是单谷函数。

The first thing to do is to determine exactly what you want to do- not in terms of some vague, ethereal objective, such as "I want to become a member of the management group," but with a definite and immediate goal.

要做的第一个件事是要确定自己要做什么，而不是要赶什么时尚或者定下难以实现的目标，例如"我想要成为管理层的一员，而是"要确立一个明确和切合实际的目标。

"The greatest success is not in never falling, but in rising every time you fall." This quotation occurred to me when I saw on television Evander Holyfield regained the heavyweight boxing championship which he had last to Riddick Bowe nearly a year before. It was really a great surprise to most boxing fans. Over two thirds had bet that the challenger would fail. The result, however, turned out to be th

一个人注定一生都要寻找一些什么当做一生的目标，没有找到目标之前，他会象是暗夜里行走的人，惴惴然，茫然，凄然，面队岔路的时候惶恐地抉择，然后就要面临由犹疑而带来的诸多负结果--悔恨、更多的迷茫、失望、自我否定、绝望，从而影响以后一系列的生活和工作行动。

In this age, the weak points of traditional education and examinationism have become more and more obvious. As a result, learning how to learn and becoming a creative person are the purpose of current education and the aim of education reforms. To achieve these goals, an interactive relationship between teachers and students in classroom must be constructed.

在这一时代，传统教育和应试教育的弊端也尤显突出，培养学会学习、学会创造的人才也成为当前教育的最重要目标和教育改革的方向，要实现这一目标，则必须在课堂教学中构建真正互动的师生关系。

It gives me daily goals that make me feel absolutely exhilarated when I accomplish them.

这成为我每天的目标，当我完成这些目标时，我感到非常高兴。

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。
