查询词典 enveloping surface

A series of erosion-corrosion test has been done to J55 steel under the influence of current of gas-liquid phase by indoor self-made devices, and the corrosion mechanism of current of gas-liquid phase to oil pipe's inner surface has been got. The results show that oil pipe's inner surface will be corroded fleetly by liquid medium and corrosion products will form on it. But at the same time, the corrosion products or protective layer will be removed from the inner surface of steel pipes under the alternate impact of high speed gas and liquid flow, and on this bare steel surface corrosion film will form again and be removed again. Thus, by these ways the corrosion is exacerbated. Surface erosion-corrosion failure comes into being with the circulation of this process going on.

本文主要在气液两相流作用条件下，通过室内自制装置，对管材钢J55做了系列冲刷-腐蚀试验，结果表明，气液两相流对钢管内表面冲刷－腐蚀的机理是钢管内表面会受到液体介质的快速腐蚀，生成腐蚀产物，同时钢管金属表面不断被具有高流速的气液相交替地冲击，不断地从金属表面脱去保护膜或腐蚀产物，裸露的钢表面又会被介质快速腐蚀形成腐蚀膜后，再被两相流冲掉，如此反复，造成管内金属表面膜的连续破坏，使腐蚀加剧，最终导致钢铁表面的冲刷腐蚀失效。

Mao Zedong Thought is a scientific concept bearing special meaning. In the early 1930s, MAO Zedong systematically proved the feasibilities of "enveloping the cities from countries and taking over power by armed forces". He also established three essentials in MAO Zedong thought: seeking truth from truth, mass line and independence, in his Fighting against bookishness, which became a milestone in the formation and development of MAO Zedong thought.

摘要］ 毛泽东思想是具有特定含义的科学概念，农村包围城市道路理论和毛泽东思想活的灵魂构成毛泽东思想的基本形态。1930年初，毛泽东比较系统地解决了关于农村包围城市、武装夺取政权革命新道路的一系列基本问题，同年5月，他发表《反对本本主义》一文，初步论述了毛泽东思想活的灵魂的三个基本点，即实事求是，群众路线，独立自主，从而成为毛泽东思想形成和发展的一个里程碑，标志着毛泽东思想的基本形成。
