But as a interest distributive mechanism, the unique characteristic of market is that it has the natural demand and ability to expand, and from which the charity organization resultantly derives as the third distributive mechanism in the same time, so that the interest distributive mechanism of government just have transitional characteristic on powerful control and functional domination relative to other mechanism, according to which it can be regarded as a mixture of imposed institutional change and induced institutional change.

同时，市场这种利益分配机制的独特之处在于，它具有自我扩展秩序的本质要求和能力，也同时会衍生出慈善组织这种第三次分配的机制出来，因而政府利益分配相对于其他利益分配机制在权力上的支配和功能上的主导也只具有过渡性，由此一种强制性制度变迁向一种诱致性制度变迁的转变就体现出来。

The tetrasyllabic words have close connection with the language system, and especially the symmetric mechanism and the analogical mechanism is decisive for its origination and development.

四音格现象的存在与语言自身的机制有着密切关系，特别是类推机制、对称机制与四音格词的产生和发展关系更为密切。

However, this dissertation is not specially on how to establish China's market mechanism of stock market, it study on how to establish the market mechanism on which the tock market works in corporate governance.

但本文又不是专门讨论如何建立我国股票市场的市场机制，而是只探讨如何建立与公司治理机制有关的股票市场的市场机制，这与股票市场发展的首要目标是一致的、无冲突的。

The uniphase C with W/≤0.3 can be synthesized without being preheated. When W/ is higher than 0.3, the sample expansion increases with the increase of W content, the reaction between W and C is incomplete, the combustion products consist of W〓C, WC, TiC, C, and unreacted W. Preheating mixtures can accelerate the completion of the reaction among Ti, W, and C. The uniphase C with W/=0.4 can be synthesized by SHS at preheat temperature of 600℃. There are two kinds of powders with size of 2-4μm and size less than 1μm in the combustion products.

通过燃烧前沿激冷淬熄试验及产物形貌特征（燃烧块断面组织和产物多晶聚合体颗粒）分析，创新性地提出了两种体系的自蔓延高温反应机制。1熔化—溶解—析出机制：当燃烧温度较高时，燃烧前沿Ti粉熔化，W和C溶解于熔融Ti里，而后C从熔融里析出。2扩散—固溶机制：当燃烧温度不足以使燃烧前沿Ti粉熔化时，通过C的扩散先形成TiC层，其后C沿着热应力导致的TiC层裂纹继续扩散，与固态Ti核反应生成TiC；同时，C扩散至W颗粒，形成W〓C，而后通过C的继续扩散W〓C转变成WC；与此同时，WC固溶至TiC里，形成C固溶体。

Thus video streaming on-demand, which is the most popular and most important distribution mode of streaming media, even today is still severely limited in scope and reach.In order to improve the QoS of the VOD system, this dissertation introduces several principles to design the video streaming on-demand system, then presents three kinds of system structures according to the scale of the VOD system, and then designs several corresponding schemes or policies to optimize the performance of the VOD system.In chapter 3, we design a multicast scheme named Dynamic Batched Patching, which can be considered as an ameliorative Patching algorithm.

There are at least two reasons to say, the first reason, there is not enough and consummate policies to protect private enterprise"s benefit and private enterprise can"t get the same political treating as government enterprises. The another one, the system of most private enterprise is non-consummate, such as not consummate at the field of management structure, bestirring and inhibiting rules, stratagem and management, and result in the poor core competence. For examples, some leaders of private enterprise are arbitrary and dont believe in other people to manage work; only trust his connection and private friends to be in charge of management; some decision made according to feeling only, not according to scientific judgment; in defect of bestirring and inhibiting rules...so on.

究其原因，一方面是因为目前中国保护民营企业的制度机制还不完善，民营企业还无法取得和国营企业相同的政治待遇，另一方面是由于多数民营企业自身制度缺损，表现在企业治理结构、激励约束机制、战略管理等方面极不完善，从而造成的核心竞争力普遍低下，如：民营企业家决策中独断专行，对他人不能放心放权；民营企业经营管理中太相信亲戚和朋友；部分决策听任感觉，缺乏科学论断；缺少激励约束机制等。
