查询词典 corrosive action

This study consists of three parts. Firstly the equivalently accelerative corrosive environment is determined through the analysis of statistic data of corrosion environment. Secondly the fatigue test is carried out under the constant amplitude cyclic loading for the specimens which are exposed in the corrosive environment for equivalent calendar time of zero year, 3 years, 8 years and 13 years. Four S-N curves with different corrosive time are obtained based on the fatigue experiment. Finally the regression method of S-N curves for experimental data is researched and a weighted least square fit is put forward in which the weigh of a group of test data is inversely proportional to the length of the confidence interval.

Based on the deterioration mechanism of corrosive medium, a lot of polymer such as ternary-polymer, adding-felt addition, hydrophobe and polypropylene fiber were added to enhance the performance of anti-corrosion, anti-penetration, conglutination and anti-cracking of original cementious material. The microstrure of cementious material was changed from the simplex hydration product of cement to the superposition structure of the hydrolysate of polymer and the hydration product of cement. A lot of the corrosive ions were prevented from the interior of concrete by this stable structure. The results of tryout indicated that the mending material has the good effect at the corrosion form of corrosive medium.

根据介质腐蚀形式的劣化机理，该文以提高修补材料耐腐蚀性能、抗渗透性能、粘结性能和抗裂性能为出发点，采用添加有机硅改性三元共聚物、增粘剂、孔隙憎水剂等多种聚合物和聚丙烯纤维对原水泥基材料进行改性，使得修补材料的内部微观结构从单纯的水泥水化产物转变成聚合物和水泥水化产物叠合的空间网状结构，这种稳定的结构能有效抵抗各种介质离子的侵蚀，在实际工程上的试用也显示出新修补材料良好的使用效果。

Social action to help the poor should have the following characteristics:the poor should see themselves as the source of the action;the action should effect in major ways the preconceptions of institutions and persons who define the poor;the action should demand much in effect or skill;the action should be successful and the successful self-originated important action should increase the feeling of potential worth and individual power of individuals who are poor.

How is collective action brought about? This perennial question has been approached from different angles. Structuralists insist that structure is the source of collective action, that structure gives rise to ideology which in turn determines collective action. Utilitarians maintain that only the community with shared benefits can engender collective action, and rational individuals may throw collective action into predicament. Constructionists are of the opinion that people act on the basis of the meanings derived from social construction, and that social mobilization is needed for such collective action.

结构主义者认为结构才是集体行动的本源，结构决定了意识形态从而也决定了集体行动；功利主义认为有着共同利益的群体成员才有集体行动的可能，但个人理性会令集体行动陷入困境；而建构主义则认为人们是依据意义的社会建构来采取行动的，但集体行动所需的共同意识、资源、成员都需要组织者积极动员，除了群体的意义建构在影响集体行动，行动者的理性也仍然在考察不断变化的周围世界的基础上参与行动抉择。
