In chapter three, various theories and experience on the dispersion of nano-powders proposed by former researchers were generalized and reviewed. Technical standards and experimental process for determining technological parameters were suggested for the dispersion of nano-scaled metal oxides in aqueous medium according to their surface wettability, surface charge, the dependence of surface charge on pH and the compatibility of surfactants with pH and pH adjusting agents. Based on these suggested standards and experimental method, highly stable and dispersive aqueous suspensoid of nm-ZnO, nm-TiO〓, nm-Co〓O〓 and nm-MnO powders were prepared successfully and surface modification on these nano-powders was also achieved.

The threshold of lithium tantalite under single-shot is found to be 1.84J /cm 2 and the avalanche rate was determined to be 1.01 cm 2 /J by calculation. We found that avalanche dominates the ablation process, while photoionization serves as a free electron provider.
在800nm飞秒激光脉冲作用下,钽酸锂晶体单脉冲烧蚀阈值为1.84 J /cm 2;在此基础上,我们通过建立钽酸锂晶体中导带电子密度演化微分方程,并数值求解,得到了钽酸锂的碰撞电离速率系数为1.01 cm 2 /J ,并得出在钽酸锂表面烧蚀中,光致电离提供种子电子,雪崩电离起主导作用的结论。

I was now in my twenty third Year of Residence in this Island, and was so naturaliz'd to the Place, and to the Manner of Living, that could I have but enjoy'd the Certainty that no Savages would come to the Place to disturb me, I could have been content to have capitulated for spending the rest of my Time there, even to the last Moment, till I had laid me down and dy'd, like the old Goat in the Cave.
我现在在岛上已经住了二十三年了,对这个地方以及对自己在岛上的生活方式,也已非常适应了。如果我不担心野人袭击的话,我宁愿在此度过我的余生,直到生命的最后一刻,就像洞中的那只老山羊一样无疾而终。同时,我又想出了一些小小的消遣和娱乐,使我的日子过得比以前快活多了。

In this sense, this paper classifies guilds' specific function according to these two functions and makes theoretic and empirical analyze of the process of function evolving of the guild which produce in the transition system. We unclose that the government absent chooses the executive administrate system upon guilds; locks the function of guilds in the function transition of relevant governmental departments and path of power-relax. The guilds are restricted by the vested-benefit of relevant department, and hence the guilds lack representation and can not provide effective incentives to the member or positive effect to the economical system and industrial development.
在此基础上,本文按照这两种职能对现实中行业协会的各种具体职能作了分类,并集中对转型期有体制内生成的行业协会的职能演化过程进行理论与实证分析,揭示了在目前政府对行业协会采取了一种行政性管制的体制,并将行业协会职能配置完善锁定在政府相关行业管理部门职能转换和放权的路径上,并受到政府有关部门既得利益的牵制,结果是行业协会缺乏行业代表性,无法为行业成员提供有效的选择性激励,没有起到促进市场经济体制完善和行业健康发展作用。

The Agent and the MAS architecture were mentioned as the core of M-GIS〓. The standards, criterions and protocols were discussed as the indemnification of M-GIS〓. The third part discussed the Agent, MAS architectures, Agent-Oriented Software Engineering and how to use these theories in M-GIS〓. Based on the clearly cognition of the Agent, MAS and AOSE, the universal Spatial-Info Agent architecture was proposed. This part put the emphasis on applying of the theories about Agent, MAS and AOSE and solving the organization problems of M-GIS〓.
本文在总结、梳理Agent、MAS以及AOSE理论的基础上,提出对Agent的认识观点与看法及如何应用Agent模型,在此基础上创造性地提出了空间信息智能体结构,并基于混合式MAS体系结构,提出来构建基于MAS体系的移动GIS集成服务框架结构,力图将Agent理论、MAS体系与AOSE的方法引入移动GIS集成服务中来,在针对复杂系统建设的GIS软件工程理论与方法上寻求创新。

This is determined by the recounting stategy of woman writers who match it with the city reading market.With female sensitivity and sharp observation they jot down various present life fragment of dramatic color,vivid plots in turns and twists,even oddness,which satisfy the reader's need to some extent.However,the biggest problem of legendary recounting affecting female metroplis novels is the modelization in creation,and severe untruthfulness of the story.This should not be neglected by woman writers if they are to surpass themselves.
它们在阅读市场化时代之所以能引人注目,显然不仅仅在于女作家们紧追中国日益都市化和市场化的历史步伐,同构性地刻画了中国都市向现代化演进的轨迹,并由此构成了中国当代都市的巨型寓言,也不仅仅在于女作家们发现并提出了女性在走向工商业都市文明的历程中,所必须重新审视的生存和价值问题,更在于女作家们凭借自身对阅读市场的敏感而迅捷地体察到了市场和读者的要求,并在此基础上确立了与之相匹配的叙事策略。
