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.

从继电器电寿命的角度，基于动态吸反力特性的配合提出了继电器的可靠性判别准则；在此基础上以触点分离初速度、触点碰撞速度以及衔铁碰撞速度等关键动态特性为判别对象，采用"应力-强度干涉法"建立了继电器可靠性容差设计数学模型，给出了下位特性参数中心值及其容差与产品可靠度之间的定量描述关系；综合考虑可靠度、加工成本及加工可行性等因素建立了继电器容差分配的多目标优化模型，基于层次分析法确定了各目标的权重系数，并采用模拟退火法实现了航天电磁继电器的可靠性容差最优分配；研究了继电器的关键工艺环节，并通过控制图对其过程能力进行了分析。

Tang Jun leaves his post very long passed, resemble a kind of game in western politics: When curule before position changes, its aides and staff can give off a word to come certainly, release a bit aerosol intentionally to play, explore popular wishes, let everybody accept reality calmingly in guess, avoid to had produced big impact to the enterprise.

唐骏离职很久就传了出来，像西方政治中的一种游戏：当一位高官有职位变动之前，其幕僚一定会放出话来，故意释放一点烟雾弹，试探&民意&，让大家在猜测中平静地接受现实，避免对企业产生过大的冲击。

Fortunately, we have a bit more time to impact the rates of macrosomia since this complication develops later in pregnancy, in contrast to the development of congenital anomalies so early.
