The chemical activating mechanism of UA is that CG can stimulate pozzolanicity more effective than gypsum because of higher solubility and looser crystal structure; but CG has poor property on retardation setting, and this shortage can be solved by mixing with gypsum; CS can offer alkali activity, which can depolymerize silica and aluminum glass, and benefit for other activity methods and overcome the disadvantage of HF on setting time; Sodium sulfate improves early strength greatly but loses the final strength. NF can improve both early and final strengths.

联合激发技术的化学激发机理是，煅烧石膏溶解度高及晶体结构松弛，比天然石膏的活性激发效率高，但降低石膏的缓凝作用，与天然石膏混合既可提高活性又能保持缓凝作用；干法电石渣提供碱激发，促进高钙灰中硅、铝玻璃体解聚，并克服高钙灰对凝结时间的不利影响；硫酸钠虽然早强作用明显，但使后期强度倒缩，NF使各龄期活性都得到提高；磨细的物理激发使高钙灰大颗粒中的CaO和富集碳组分被磨细、分散，活性增加而危害性降低。

Objective To introduce a new procedure modifying upper eyelid's dermatocele and excessive fullness.Methods In this procedure,we design incision at sub-eyebrow but not up-eyelash to do upper eyelid blepharoplasty.Using this approach,we smooth the wrinkles ion upper eyelids,excise superfluous skin and pseudo-herniated orbital fat so as to make patients youthful.Results Through this method.aging upper eyelids can be made youthful effectively and naturally.

目的 介绍治疗上睑臃肿松垂的新术式方法我们采用眉下切口而不是传统的睫毛上切口进行上睑整形，充分舒展松垂皱缩的上睑，并去除膨出的上睑眶隔脂肪及余的皮肤和轮匝肌组织，在达到改善上睑松弛使病人外貌年轻化的目的。

It's rare when star patterns on our sky's dome have anything to do with real associations of stars in space, but Graffias, Dschubba and Pi Scorpii are thought to be loosely bound by gravity.

当星星在我们的上空的星际间和一些真正的星星协会一起不做任何运作的时候，这样的现象是罕见的。但是Graffias， Dschubba 和 Pi Scorpii 由于重力被认为是松弛结合。

Mucous membrane protective screen is formed by the join between cell of alvine mucous membrane and cell, atrophy of cell of alvine mucous membrane, wither dies, cellular connective can send alvine path to connect flabbily appear a gender to increase, provide passageway; chemical protective screen for the bacterium inside bowel and toxin the digestive juice that shows epithelial excretive mucus and alvine memory are in bowel and digest enzymatic the chemistry that waits for material to reach its to develop.

黏膜屏障由肠黏膜细胞和细胞间的连接构成，肠黏膜细胞萎缩、凋亡、细胞连接的松弛可致肠道通透性增加，为肠内细菌及毒素提供通道；化学屏障指肠上皮细胞分泌的黏液及肠内存在的消化液和消化酶等物质及其发挥的化学功能。

Firstly,proposed an extended rough sets model based on concordance relation which relaxed the indiscernibility relation and tolerance relation.Secondly,redefined some concepts,such as the indiscernibility degree between two objects,the indiscernibility degree between two clusters,integrated approximation rate of the clustering result.

首先在经典粗糙集理论的基础上，通过松弛对象之间的不可分辨和相容性条件，得到了基于和谐关系的扩展粗糙集模型；然后定义了新的个体间不可区分度、类间不可区分度、聚类结果的综合近似精度等概念，提出了新的混合数据类型层次聚类算法。

At last, natural frequencies of practical pre-stressed composite space truss are tested with pulsatory method on construction site and its damping ratio is calculated, which gives another important data for engineering design. In addition, through the model experiment of pre-stressed rectangular square pyramid composite space truss, the correctness of characteristics of internal force and the feasibility of tension recovery method are proved.

最后，在工程施工现场用脉动法测试自振频率，并借助于振动衰减曲线和半功率点法计算出预应力组合网架——钢与混凝土的混合结构体系——的阻尼比，此又为工程设计提供了一理论依据；另外，通过正放四角锥预应力组合网架的模型试验，验证了结构内力分布特点的正确性以及张力松弛法的可行性。

The microstructure and thermal physical properties of the surface reactional layer determine the range of strength improvement.Stress relaxation was benifical for strength,but the oxidation-induced bubbles and crack weaken the specimens.

热处理引起的应力松弛也有利于材料强度的提高，但氧化过程中产生的表面气孔及冷却过程中产生的表面微裂纹会引起材料强度的下降。

Using semidefinite programming relaxation and randomized rounding, we give the corresponding polyniomal approximation algorithms for some NP-hard combinatorial optimization problems.

我们对于一些NP-难的组合优化问题，采用半定规划松弛和随机舍入的方法设计了多项式时间的近似算法，这些算法的性能比都是目前为止最好的结果。
