Standard test method for evaluating the effective surface area of zinc - oxide in rubber 评估橡胶中氧化锌的有效表面积的标准试验方法
50mm polyurethane foam steam heating system : external steam channels are weld to the tank underside to give an effective surface heating area of 8 . 0 sq . m . the steam inlet / outlet connections are 11 / 2 inch bsp male 目前中国是世界上最大的黄磷出口国,为与国际运输业接轨,罐式集装箱对我国磷化工产品的贮运是十分必要的。
In tangshan , hebei , an advisory body , daheng surface treating research center , has been set up jointly by hebei institute of technology and our company . working in the center are a number of celebrated professors and personnel with doctor or master degrees . they are constantly developing newer and more effective surface treating agents in cooperation with the companys engineers 在唐山,与河北理工学院联合建立大恒表面技术研究所,所里拥有多名硕士及博士,同时还聘请多位著名教授担任技术顾问,对表面处理技术机理做更深入的研究,不断开发最新型的表面处理剂产品。
This test is based on homogeneous soil in foundation , and divided into two phases . the first is to stimulate the construction flow to excavate the pit ; the second phase is destructive test . because the pit is stable in the first phase and the research is point to the geometry shape of the failure surface , moreover , limited to the test condition , the effective surface force is applied to the pit 此次模拟试验主要是针对简单均质的基坑土层进行研究,试验分为两个阶段,第一阶段主要是以相似工况模拟基坑开挖,第二阶段主要是破坏性试验,即由于在第一阶段基坑在开挖范围内能够自稳,为使基坑达到破坏状态以研究滑面几何形态,限于试验条件,采用“等代面力”的方式施加超载。
