Dark rod knife gate valve with disc buried in the body cavity is completely isolated from the external environment, it is suitable for pip which is installed in the swage pool and body is immersed in the liquid . If disc is not isolated from external environment ,disc will be corrupted immediately , so it will affects life of the valve.

暗杆式刀闸阀是闸板埋在阀体内腔完全与外界环境隔绝的一种阀门，它适合与那些安装在污水池底下阀体浸泡在液体里的管道，如果不把闸板与外界环境隔离，那么闸板就很快会被外界环境所腐蚀，影响了阀门使用寿命。

Effect of composites and microstructure on normal pressure core leach was investigated,the size precision of the lumen and good teachability can be assured when amount of active additives is 13%;good leachability can be ensured when porosity factor be controlled higher than 35%; the core mixed by machine has good leachability than by manual.

研究了氧化铝陶芯的组成与微结构对脱芯性能的影响，发现活性添加剂的量应控制在13%才能同时保证铸件内腔的尺寸精度和脱芯性能；型芯的孔隙率应控制在35%以上才能保证常压下易于脱除；球混型芯要比手混型芯的脱芯性更好。

The larger hollow inner cavity has the similar function as Vacuum Flask, playing a role of good insulation.

隔热功能。较大的中空内腔同保温瓶的功能相似，起到了良好的隔热作用。

The intact functional endothelial cells play important roles in maintaining the self-stabilization of vasculature and normal blood circulation.

血管内皮细胞是覆盖于血管内腔表面的单层扁平细胞，其完整的结构和功能是维持血管壁自我稳定和正常血液循环的基础。

Statistic analysis to the mechanism and failure of bleed out caused by broken corner is made, and the result shows that the main reason of bleed out caused by broken corner is the inhomogeneity of the shell of crystallization and the inhomogeneity of the secondary cooling system which are caused by the processing parameter in the inside of copper pipe and the wear-out in the corner during the service.

对角裂漏钢机理及现场角裂漏钢事故进行统计分析，认为造成角裂漏钢的主要原因是铜管内腔的工艺参数及使用过程的角部磨损造成的出结晶器坯壳不均匀和二冷系统冷却的不均匀性。

通过超声检测，肝内腔静脉闭锁，仅存有下腔静脉。

At ultrasonic examination, the intrahepatic ena caa was found to be atretic, leaing just an infrarenal ena caa.

通过超声检测，肝内腔静脉闭锁，仅存有下腔静脉。

This flow is not sufficient to regulate intra cavitary pressure in the event of a major leakage.

但一旦出现大的泄漏，此低量的气流便不能足够调节内腔压力。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
