不断伸缩

From the construction of network society, it makes the content provider as the main body, and builds from top to the bottom, the users are considered as a group conception.

Analysis of the main reasons is because of fatigue caused by factors such as the copper support ring was broken and the piston rod in the hydraulic cylinder telescopic frequently, the fracture茬口constantly scraping the inner wall hydraulic cylinder mill will pick缸壁, resulting in injury China, so that the speed of decline in hydraulic cylinder; job with the passage of time, strain and缸壁sealing ring, wear ring injuries are increasing, with China to increase the volume, and finally resulted in a serious decline in the speed of hydraulic cylinders.

分析主要原因是，由于疲劳等因素造成的铜质支撑环断裂，在液压缸活塞杆的频繁伸缩中，断裂茬口不断刮磨液压缸内壁，将缸壁拉毛、拉伤而导致内泄，使液压缸速度下降；随着工作时间的推移，缸壁拉伤和密封环、耐磨环的损伤都不断加重，内泄量加大，最后造成液压缸速度严重下降。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
