ZL03 2 354312.The innovations include: automatic self-closing and reliably sealed valve structure: the design of duplex valve clack with pilot valve to tackle the problem of reverse seal structured valve being difficult to be opened; an automatic drain control device to automatically drain the remaining water from the hydrant; protective plate provided between the hydrant body and the valve block to serve as a connection between the hydrant body and the valve block, which is the first one to be damaged when the ground hydrant is clashed, and prevent pulling-off of the whole above-ground part of the fire hydrant, so as to properly protect the main parts from any damage. The self-closing and reliably sealed valve now prevents drain of water, and only the damaged protective plate is needed to be replaced before immediate re-operation. Thus the repair work after clashing is very easy and simple.

其创新点为：具有能自动关闭并可靠密封的阀门结构：采用有先导阀复式结构阀瓣设计，解决反向密封结构阀门开启沉重费力的难题；设计自控排水装置，能自动排除栓体内余水；在栓体和阀体之间设计撞裂板，它既起到连接栓体和阀体的中介作用，又可在地上消火栓被撞击时率先破裂毁坏，并使露出地面的栓体不见整体脱落，有效保护各主体部件的完好无损，而此时阀门的自闭式结构可靠密封阀门阻止水源外泄，修复时只需更换损坏的撞裂板即可立即复位投入使用，使被撞后的修复工作变得十分轻松简便。

METHODS: Calvarial osteoblasts of neonate rats were cultured under conditions of normal gravity(1G) and simulated weightlessness induced by clinostat respectively. The total RNA in cells was isolated in different time points (24, 48, 72 h). Reverse transcription PCR analysis was made to examine the gene expression of α5,αv and β1 integrin subunits.

培养的大鼠乳鼠颅骨成骨随机分为对照组和失重组，在实验的24， 48和72 h提取细胞总RNA，进行反转录PCR，检测整合素的α5，αv和β1亚单位mRNA表达，并计算与内参照β肌动蛋白 beta？？？？

The total RNA in cells was isolated in different time points (24, 48, 72 h). Reverse transcription PCR analysis was made to examine the gene expression of α5,αv and β1 integrin subunits. Each value was normalized against that of β actin mRNA.
