Abstract］ objective to understand the medical institutions in the use of pressure steam sterilizer in the effect and the influencing factor,explore regulatory measures.methods with the spot investigation and scene examination,3mtmattest pressure steam sterilization and biological indicator train was used to monitor the effectiveness of disinfection.results in the monitoring of the 238 chinese medical institutions equipped with pressure steam sterilizer 337 units,the sterilization rate was 95.2%,medical institutions had different levels of disinfection and sterilization equipment,a large gap was between the level of management,equipment failure,non-standard operation,operator training without sterilization were the main reasons for failure.conclusion in medical establishment with the pressure steam sterilizer,antiseptic qualified rate is not too high,strengthening the pressure steam sterilizer purchase card management,standardizing the operation,stepping up supervision are the key to increase pressure steam sterilizer sterilization effect.

目的 了解医疗机构使用中压力蒸汽灭菌器使用效果及影响因素，探讨监管措施。方法采取现场调查及现场检测相结合的方法，采用3mtmattest压力蒸汽灭菌生物培养指示剂进行消毒效果监测。结果在监测的238家医疗机构中共有压力蒸汽灭菌器337台，灭菌合格率为95.2%，各级医疗机构对消毒灭菌设备的管理程度差距较大。设备发生故障、操作不规范、操作人员未经培训等是造成灭菌不合格的主要原因。结论医疗机构使用中压力蒸汽灭菌器灭菌合格率不高，加强对压力蒸汽灭菌器进货索证管理，规范操作，加大监管力度是提高压力蒸汽灭菌器灭菌效果的关键。

The calculation and experiment results show that the maximum lifting pressure performance decreases with the increase in throat diameter of channel of variable section, water flux of low pressure and pressure ratio of steam nozzle, and has its minimum value with water nozzle annular space. The coefficient of maximum lifting pressure performance may be as high as 26. In the design of steam injector, the larger pressure ratio of steam nozzle and the smaller water nozzle annular space are selected, the higher lifting pressure performance could be obtained.

计算及研究表明：极限升压能力随变截面混合腔喉部直径、被升压的低压水流量和蒸汽喷嘴压比增加而降低，随环形水喷嘴间隙的变化出现了最小值；计算得出变截面超音速汽液两相流装置的极限升压能力可达26；在设计升压装置时应尽可能选取较大的蒸汽喷嘴压比和较小的环形水喷嘴间隙。

It works as shown in Figure 2b, when the work when the system is high pressure, EF mouth also in high pressure, high pressure Balance Valves unloading of oil equivalent one-way valve open and the unloading valve 3 1 contact; when the pressure exceeds the safety valve unloading having a set pressure, unloading relief valve to open, the return oil through oil path b to uninstall the spool 4, left, unloading Safety valves valve spring to overcome the spring force 5, unloading spool shifted to the right, EF population of high-pressure oil through direct discharge port T Dutch tank.

其工作原理如图2b所示，当工作系统处于高压状态时，EF口也处于高压状态，高压油打开等值卸荷单向阀3与卸荷安全阀1接触；当压力超过卸荷安全阀调定压力时，卸荷安全阀开启，其回油经油道b到卸载阀芯4左端，克服卸载阀弹簧5的弹簧力，卸载阀芯右移，EF口的高压油经T口直接卸荷油箱。

The paper carried out combination calculation on two kinds unsteady flow problems of pressure water diversion of hydropower station (i.e. pressure fluctuation of water hammer and mass fluctuation of surge chamber), which changed many analytical error caused by considered these two phenomena separately, and such result meets the inherent rule of pressure water diversion system transient of hydropower station much more than before.

2实现了水电站有压引水系统中两种非恒定流问题(即水锤的压力波动和调压室的质量波动)的联合计算，改变了把这两种现象分开单独考虑所带来的分析误差，这样的计算结果更加符合水电站有压引水系统中过渡过程的内在规律。
