查询词典 bounding surface

The result showed that the surface architecture and ultrastructure of I.punctatus ' gill and secondary gill lamellae were similar to those of other teleosts. The surface of gill arches and gill rakers was covered with pavement cells which were characterized by circular microridges, and secreting-holes were found among cells on the surface of gill arches. The base part of gill rakers were bigger in terms of diameter. The pavement cells' surface of gill filaments' middle part was characterized by microridges with fine lateral protuberances on both sides which were either fused or interruped, while the microridges disappeared on the pavement cells' surface on both top and base parts of gill filaments, forming dense granulated protuberances. The height and interlamellar space of secondary gill lamellae in I.punctatus were relatively higher and bigger, respectively.

Ceilings should be ac-cessible for cleaning, and ideally, the surface should he coved where ceilings and walls meet In many food-production areas, the ceiling must have thermal in-sulation This may be necessary either to prevent surface condensation or to reduce the energy costs of maintaining low environmental temperaturesWalls should also be insulated, to prevent surface condensation They should be free from rising damp and be protected, where appropriate, from damage by forklift trucks, by use of a guard rail In modern factories, there is always a coved surface where walls meet the floor It is also usual for there to be a coved surface where walls join at right angles.

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。
