查询词典 wall

Based on a thorough analysis of the character and mechanism of city-retaining-wall structures, the design theories, construction technology, new wall types and development tendency are deeply discussed. Besides, the characteristics of various types of city retaining wall are discussed, and the usual methods for earth pressure calculation are summarized. For the anchored bar retaining wall, the anti-pulling bearing mechanism of anchored bar is first probed into, from which anti-pullforce computation method are obtained. Combined with quite a few engineering examples and spot tests, the advised design and calculation methods of anchored bar are verified. From the abundant spot measured date, an adjusted hyperbolic model is put forward to determine the anti-pullforce bearing capacity. Furthermore, a new type of H-like block retaining structure is advised with its working mechanism deeply discussed as well.

Two pairs of chutes and holes on the cleaning base and the brushes form the double chute swing mechanisms by the connection of an axis and cause the brush to cling to the wall surface to clean by the friction feedback, thus achieving effective cleaning when walking error occurs and the pipe section changes, furthermore, the larger the friction on the wall surface is, the larger the forward pressure on the wall surface is, therefore, the dirtier the wall surface is, the higher the cleaning efficiency is.

清扫底座与刷子夹上的两对滑槽和孔通过轴的连接形成双滑槽摆动机构，并通过摩擦力反馈使得刷子能够紧贴壁面进行清洗，从而在出现行走误差和管道截面变化时都能够有效清洗，并且壁面摩擦力越大刷子作用在壁面上的正压力越大，因此壁面越脏时清扫效率越高。

In the present work, based on the mechanism of low - temperature corrosion, an opinion was presented by theoretical analysis and computation, that is the vacuum boiler can not avoid being corroded completely under low temperature, but the corrosion is very weak no matter if the exhaust gas temperature is higher than the flue gas dew point; it was obtained the relationship between the corrosion velocity of metal wall and wall temperature along gas pass of vacuum boiler, and the one between the corrosion velocity of metal wall and wall temperature under the condition that the flue gas temperature is lower than the acid dew point.

文章从锅炉发生低温腐蚀的机理人手，通过理论分析计算并通过实践检验，提出了真空相变锅炉虽然不能完全避免低温腐蚀问题，但不论排烟温度是否高于烟气露点，低温腐蚀的程度都很弱的观点；给出了真空相变锅炉沿烟气流程金属壁面的腐蚀速度与壁面温度的关系曲线，和烟气温度低于酸露点时金属壁面的腐蚀速度与壁面温度的关系曲线；同时，文章推荐真空相变锅炉的设计排烟温度取130℃左右的低排烟温度。
