From the lifespan of relay point of view, a reliability criterion was provided based on dynamic characteristics of anti-forces. Mathematical model of tolerance design with reliability was set up under usage of "stress-strength interference method", taken some critical dynamic characteristics as identification objects such beginning of contact separation speed, speed of collision and gag bit impact velocity. This model showed that lower values of characteristic parameters center and quantitative descriptively relationship between tolerance and product reliability. Multi-objective optimization model of relay tolerance distribution was completed when some factors such as reliability, processing costs and its feasibility into consideration. Based on Analytic Hierarchy Process to determine weight coefficients of various objectives, and usage of simulated annealing, this study performed optimal reliable tolerance allocation of space electromagnetic relay, and then key technology segments were analyzed, accompanying its course measured by controlling chart.

Analysis results on townships and villages general statuses showed township health center and village clinic are the major health care facilities in rural poor areas. The number of staff in 36 THCs and 104 VCs were a little lower than the national average. In township health centers, 59. 9% staff are with primary or without any professional titles and 35. 9% of the total staff have no professional degrees. The average gross value of fixed assets per THC is 186000 yuan, among which special equipment values 41000 yuan. Among professional buildings 43. 3% of total area were dangerous. Only one THC can provide emergent service. 47. 2% THCs be able to diagnose and deal with common emergent stomachache. The provision of health services was lower than average level of national rural areas. Frontier Model analysis showed regression coefficients of total outpatient emergency service, total inpatients, average personnel income, number of total staff, number of doctors and technical index were all larger and positive. It meant that these variables would contribute more to the cost-frontier, and their increase would cause the total health cost rising. So increasing health service provision, improving service quality and functions of health facilities may be the best ways to increase efficiency of these facilities. Also the model showed THC inefficiency eu was 1. 68, which means 40% of the cost wasted. Apart from internal and external factors, residents'health care utilization deficiency and inequity is one of major factors causing inefficiency eu.
乡、村基本情况结果表明,农村贫困地区乡卫生院和村卫生室是农民就近就医的主要场所;36所乡卫生院以及104所村卫生室的人员数量,略低于全国同期农村平均水平;在乡卫生院中,初级职称和无职称者的比例占59.9%,无专业学历者占35.9%;平均每院固定资产总值18.6万元,其中专用设备4.1万元,业务用房中危房面积占43.3%;36所卫生院中,具备急救条件的只有1所,能诊断和处理常见急腹症的占47.2%;卫生服务提供量均低于全国农村平均水平;Frontier模型方法显示,总门诊人次、总出院人次、平均人员工资、人员总数、医生数和技术指数等指标的回归系数较大,且均为正数,即这些变量对"前沿"成本的贡献较大,其正向变化均会带来卫生服务总成本的增加,表明增加卫生服务提供量,提高质量以及完善机构服务功能,是提高乡卫生机构效率的有效途径;同时Frontier模型结果显示,卫生院的低效率〓为1.68,经换算即40%的成本处于浪费状态;影响乡卫生院低效率〓的因素有外部和内部的,而需方卫生服务不公平及利用不足是其主要因素之一。
