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。

在乘客电梯的使用过程中，因电梯软、硬件故障或电网故障，使电梯乘客被困于电梯中，通常情况下，电梯维保员接到被困的信息时，进行人工救援：首先把外电网切断，将电梯曳引机抱闸松开，进行人工盘车，此时必须两人配合才能完成。

It is clarified for the first time that the thermal fatigue failure of solder joint is actually a creep strain low cycle fatigue failure, and a physical model for creep fatigue crack propagation has been proposed. It was pointed out that creep strain increases in the high stress area ahead of the tip of thermal fatigue crack, results on one hand that the slide of crack tip increase, inactivation more serious and crack close length increases, the other hand, that intergranular crack exists, whose direction will affect the fatigue crack propagating.

本文首次阐明了焊点的热循环失效本质上是以焊点内循环蠕变为主要应变的低周疲劳失效，并在此基础上提出了蠕变疲劳裂纹扩展的物理模型，指出热循环裂纹前端的高应力区内，蠕变加剧，使裂纹前端滑移增加，裂纹钝化加剧，导致随后的裂纹闭合扩展长度增加；同时蠕变也使裂纹前端的高应力区出现晶间裂纹，蠕变沿晶裂纹对主裂纹扩展的影响取决于沿晶裂纹的连接方向。
