针对热风干燥水产品过程中常出现的表面干燥脱水过快、内部水分扩散通道易堵塞，造成产品水分不均匀度值较大，影响产品烘后品质问题，设计了专用U型隧道式水产品烘房，并对横流干燥、气流正反向切换、干燥介质温度及湿度在线控制、以及热能循环利用等关键技术进行了分析与研究。

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.

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.
