可预防的

The lifetime prediction with increases in switch cycles is strongly dependent upon the device dimensions and characteristics of structural thin films. Thus, understanding of fundamental observed failure mechanism and mechanical response respected to external loads plays an important role in products design and lifetime prediction of MEMS.

因材料的疲劳行为发生时并无任何明显的外观改变，而是一种潜在的行为，且没有明显的塑性变形区，对元件的安全以及寿命的影响更是无法明显观察并加以预防，因此可藉由疲劳试验来预测元件之寿命，并进一步对元件进行防范和更替的动作。

To discuss the cause of peril,「The Theory of Accidental Causation」－ interaction between worker and machine, consequence and frequency, non safety cause, cost of peril and preventive action taken by management, then,「Domino Theory」－causations of peril can be divided into 5 dominos.

灾害原因探讨，其中「事故因果论」--人机间的互动、后果严重程度与发生频率间的关系、不安全行为原因、事故的成本以及管理者在事故预防上所应扮演的角色，再就「骨牌理论」--事故发生的因果关系可归纳成一连串五个主要因子，视之为五张骨牌domino）。

Integrate low temperature and ultra-dry to excogitate better method to prolong seed longevity, at the same time, we found out the optimal method of ultra-dry preservation, screen out to the excellent desiccant with low cost and good effect, validate the method of ultra-dry can use to deal with and conservation even more large numbers of tobacco seed, yet explored seed vigor comedown rule of tobacco seed, that avoid seed vigor loss prematurely.

It prevents excessive memory swapping and makes sure that a certain amount of memory isalways available, which results in performance increase and lower response times, especially if youare running many applications at the same time and tend to switch between them quite often.

该软件可以预防过度的内存交换并且可以确保一定数量的内存维持在可使用状态。这就可以确保性能的提升和较低的响应时间，除非你正在同时运行许多应用软件并且有在这些程序之间频繁切换的趋势。

objective to discuss perioperative complication and management of patient with high risk copd following esophagectomy.methods 45 patients with high risk copd underwent esophagectomy with epidural block combined with general anesthesia.perioperative treatment included smoking cessation,chest physiotherapy,prevention and control of infection of air way and appropriate bronchodilators of air way,breathing exercises,nutrition support and oxygen therapy.painkiller was instilled after surgery,early exercises,ensuring unobstruction of the air way,mechanical ventilation was applied when needed.results 3 had hypoxaemia in operation.after surgery,all patients had spo2 somewhat declined.6 had lung infection.6 were removed of bronchial secretion by bronchoscope.2 were supported by ventilator by using intubation.2 underwent tracheotomy.1 had disturbances of acid base balance and treated by using hydrochloric acid muriatic acid.all patients recovered rather smoothly and discharged from hospital.conclusion high risk copd is not the absolute contraindication of esophagectomy.active management before and after surgery ensures the safety and recovery of patients.

目的 探讨重度慢性阻塞性肺疾病简称慢阻肺病人食管切除术围手术期常见并发症及其处理。方法 45例重度慢阻肺的病人在全麻联合硬膜外阻滞下进行开胸食管切除手术，围手术期处理包括术前戒烟、胸部理疗、预防和控制呼吸道感染、解痉化痰、呼吸功能锻炼、营养支持和氧疗；术后硬膜外镇痛、早期锻炼、保持呼吸道通畅，部分病人予以呼吸支持。结果术中3例出现低氧血症。术后所有病人pao2均有不同程度的下降，6例出现肺部感染，6例行纤维支气管镜吸痰，2例通过气管插管给予呼吸机支持，2例行气管切开术，1例酸碱平衡紊乱使用盐酸精氨酸治疗。所有病人均痊愈出院。结论重度慢阻肺病人并非开胸食管切除手术的绝对禁忌证，积极的术前准备和严格的术后管理可减少和控制术后急性发作，有助于确保此类病人的围手术期安全和康复。

In addition, the prevention of sexually transmitted infections by the indirect, such as condyloma, gonorrhea, AIDS and other measures are: to develop good personal hygiene habits, do not use other people's towels, basins, razor, etc.; in public places such as hotels, bath, swimming pool to enhance awareness of self-protection; not drugs, not easily use the imported blood products.

另外，预防可经间接感染的性病，如尖锐湿疣、淋病、艾滋病等的措施是：养成良好的个人卫生习惯，不使用他人的毛巾、盆、剃刀等；在公共场所如旅馆、浴池、游泳池等加强自我保护意识；不吸毒，不轻易使用进口的血液制品。

Topiramate induced hypohidrosis is reversible, but can be clinically significant during heat stress and exercise challenge. This side effect challenges patients'confidence of long term drug therapy. On the other hand, although hypohidrosis is an adverse effect of topiramate when used for other indications, its anti-sweat producing effects may be beneficial in conditions of hyperhidrosis. How topiramate induces its antiperspirant effects is unclear.
