Influences of the tube wall thickness reduction after hydraulic expanded joint on the residual contact pressure 液压胀接后管壁的减薄对残余接触压力的影响
Corrosion and pitting defects in pipe work are major problems in the oil , chemical , and other industries 管道的腐蚀、壁厚减薄等缺陷是石油、化工和水暖工业中面临的主要问题。
But majumdar explains they dropped the switching voltage to a sufficiently low one volt by thinning the channel walls 但马强达说明，他们在通道壁减薄后，已将开关电压降低至一伏特。
These defects can occur at the outer or inner surface of the pipe and can lead to a serious loss of pipe wall thickness 这些缺陷既可能发生在管道外壁又可能发生在管道内壁，通常致使管道壁厚减薄。
The spatial heterogeneity of the lithospheric mantle beneath north china may have resulted from the diachronous thinning processes 华北岩石圈组成的空间不均一性可能与岩石圈减薄过程的时空差异有关。
Thus it is necessary to find out an reasonable approach for design of drum ' s wall based on scientific theory and experiment 为此，有必要研究并寻求一种更加科学合理又能减薄卷筒壁厚的设计理论和方法。
Discussion on the lithospheric thinning of the north china craton : delamination ? or thermal erosion and chemical metasomatism 关于华北克拉通燕山期岩石圈减薄的机制与过程的讨论:是拆沉,还是热侵蚀和化学交代
The conclusion can be drawn that this method can detect inner wall diameter or wall thickness of cylinder - shaped equipment 经数值实验验证，本方法可对薄壁高温圆筒状热设备的内壁减薄给出高精度的定量检测结果。
Make use of high strength , it is still keep the machinery function of car body when its thickness gets thin , as a result , remit the car weight 利用高强度特性，可以在厚度减薄的情况下依然保持汽车车身的机械性能要求，从而减轻了汽车重量。
The technical scheme for implementing the back - illuminated charge - coupled device by thinning the substrate of a conventional charge - coupled device chip is studied 设计了对常规电荷耦合器件芯片进行衬底减薄进而实现背照电荷耦合器件的技术方案。
