为此 ，通过对科学技术在经济可持续发展方面的促进作用进行初步的研究，指出：科学技术既可以突破劳动者自身对经济可持续发展的约束又可以突破生产资料对经济可持续发展的约束，从而为进一步研究科学技术与经济可持续发展之间的关系提供了理论基础。

Facing the fact that the inefficient china securities market, the article analyzes carefully the reason for low contract efficiency from the following aspects such as property rights, insufficient information regulation and the structure of regulation mechanism. What抯 more, the article points out reregulation is a possible way to normalization development of china security market after analyzing the disadvantages of strengthening regulation and deregulation. At length, the thesis paper will discuss the design of reregulation mechanism from the principles of incentive and constraint regulation institution and punishment mechanism.

面对中国证券市场管制低效的局面，本文从产权、信息不足约束以及管制机构治理结构等方面详细剖析了造成管制低效的原因，进而在分析加强管制和放松管制等论点的不足之后，指出再管制是通向中国证券市场规范化发展的可行之路，而且从管制机构激励约束、惩罚原则等方面讨论了再管制实施机制的设计问题。

The recovery strategy for the customer time window disruption is given,to guide to design the other recovery strategy for the VRPTW disruption;By setting the single dummy depot or the multiple dummy depots,the transition that the jump-offs of vehicles on the way are reposited to the depot is proposed,making the algorithm for the VRPTW solve the disruption recovery model as before;the customer time window disruption is analyzed,to help measure the other deviation for VRPTW;A new handling constraint method based on genetic algorithm is designed,avoiding the difficulty of selecting the penalty factor in penalty strategy and makes the handling constrain simplify.

本文给出了客户时间窗变动的扰动恢复策略，可以指导设计VRPTW其他扰动恢复策略；通过设定虚拟单车场或虚拟多车场，将干扰发生在途车辆的起点复位到车场，使VRPTW求解算法同样可以用于处理扰动恢复模型；对客户时间窗变动对系统造成的干扰进行了度量，为VRPTW其他扰动度量提供了指导；设计了一种新的约束处理方法，避免了惩罚策略中选取惩罚因子的困难，使得约束处理问题简单化。

In this paper, it is shown that the increment of the plasma confinement time without consideration of radiation losses is a good scale for evaluating the plasma confinement improvement during the L-H like transition induced by electrode bias in tokamaks, if the ratio of the radiation power to the total loss power in the transition changes evidently.

辐射下降表明进入等离子体的中性粒子通量减少。这是中性粒子再循环的减小而造成的。同时，边缘密度和边缘温度下降，中心温度上升，约束得到改善，能量约束时间增加。径向电场是控制托卡马克等离子体从L模过渡到H模的关键因素。如果径向电场足够强，极向ExB旋转产生很大的剪切，剪切能够抑制边缘湍流1j。
