查询词典 fractured 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。

The model can reflect the multi-sets feature of the rock masses in practice, consider the influence of the joint orientation and strength to the rock masses deformation feature, and simulate the simultaneous sliding, tension and close behaviors of the multi-sets jointed rock masses extending the joint surface, and reflect the plastic deformation induced the rotation of the principle stress axes. The result can be extended to fractured rock masses with arbitrary set joints.

The mountain materials, Russia expected, the Qinghai-hat "tremolite" small crystals have a certain arrangement of different materials, such as Qinghai, the crystal fibers are arranged mostly in the same direction, showing a translucent and strong, and this has not been a natural Sorting mountain materials, micro-fractured, micro-cracks will affect the diffuse light glossy surface, it is generally not a good oil lubrication performance sense, but there are also individual mountain material, because structure is very good, so oil is also very good, used to play, and Tian's friends must have taken note of this in!

而山料、俄料、青海料"透闪石"小晶体的排列方式有一定的不同，如青海料的晶体纤维的排列多为同一方向，表现出透光性强，并且这种没有经过自然分选的山料，微裂隙发育，微裂隙对光漫反射会影响表面的光泽感，所以一般表现不出很好的油润感，但也有个别的山料，由于结构非常好，所以油性也非常好，经常玩和田玉的朋友一定也注意到这一点了！

It was shown that winter-time natural convection in the fractured-rock embankment began to occur in the side slope portions and developed from two side slope portions to the middle portion of embankment with lowering of surface temperatu...

通过引入自然对流指数，分析了自然对流降温效应随路堤碎石层填筑厚度的变化规律，其可分为恒零区、急增区和缓变区3个阶段，急增区的起点和终点对应于路堤碎石层填筑的最小厚度和最大厚度。最后，利用自然对流指数具体计算了不同粒径碎石层填筑的临界厚度。
