Dynamic Optimization Problems has attracted more and more attention recently, and a number of methods have been introduced to solve them.

近年来，越来越多的演化计算研究者对动态优化问题产生了很大的兴趣，并产生了很多解决动态优化问题的方法。

In this paper, we construct the differential equation to solve the unconstrained optimization problem. Such methods solving the ill-conditioned problems are very effective. It indicates that the asymptotically stable region of explicit the Euler method to solve the differential equation equals to the descent region of the gradient method to solve the original unconstrained optimization problem.

我们发现，在用Euler方法求解二次优化问题的等价动力系统的方程时，由方法的步长确定的稳定区域对应于这些方法所得到的迭代公式的步长满足单调下降算法的条件确定的单调下降区域，因此我们可以利用这个性质构造解无约束优化问题的数值方法而不采用标准的常微分方程的数值求解公式。

At first, a rigor mathematical definition of the problem is presented, then the analytical properties of the feasible region are studied, and the solution existence is examined.

Then its optimization result was presented by means of genetic algorithm because of some discrete parameter , complicated target function and inequation constraint.

考虑到该优化问题的目标函数非常复杂且涉及到不等式约束、离散变量的处理技术等问题，采用了基于遗传算法的优化计算方法。

An infeasible sequential system of linear equations filter algorithm is presented to solve this type of problem.

The high speed advantage of FPGA's operation is made hard to demonstrate for the inconsequence in structural arrangement. The pipeline technology had well solved this problem. We presents a new pipeline optimization technology of inventer's control system based on FPGA,and completed the optimization design of the inventer controller. Analyzed the design process in detail and offered a kind of thought for the people who devoted to FPGA's application in power electronic field.

分析了"流水线操作"等设计优化问题，并针对逆变器控制系统中，控制系统算法呈多层结构，且层与层之间还有数据流联系，其执行顺序和数据流的走向较为复杂，不利于直接采用流水线技术进行设计的特点，提出一种全新的"分层多级流水线"设计技术，有效地解决了复杂控制系统的流水线优化设计问题。

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。
