序进 meaning in Chinese
progression
Examples
- Moment estimation of the accelerated life testing - circular - progressive - stress weibull distribution under censored samples
分布场合下循环序进应力加速寿命试验的矩估计 - The step stress alt and data processing of the radio fuze under the condition of three - parameter weibull distribution
分布序进应力加速寿命试验损伤失效率模型下的统计分析 - The step - access accelerated life testing ( ssalt ) and progressive stress accelerated life testing ( psalt ) are two kinds of effective methods which are widely used in life testing because of the development of their theories
步进应力加速寿命试验和序进应力加速寿命试验是有效和经济的寿命试验方法，随着理论的日趋成熟，在实践中开始得到应用和推广。 - In this paper , we first discuss statistical model and data analyses under accelerated life testing by circular - progressive - stress when the life distribution follows log - normal distribution , then give three methods of estimators of parameters
本文在产品寿命服从对数正态分布的场合下，讨论了循环序进应力加速寿命试验模型，给出了相应参数的几种统计分析：极大似然估计；极大似然估计与回归相结合的估计；最小距离估计。 - In chapter3 , we discuss the multiplicate progressive stresses accelerated life test . under the weibull distribution and an invers power law model we first present a necessary and sufficient condition for the existence and uniqueness of mle for the exponential distribution , then give estimators and confidence intervals of the parameters based on the blue . finally , we study them by using monte - carlo simulation
第三章首先指出了一组序进应力加速寿命试验下weibull分布分布参数的mle不唯一，然后给出了p组序进应力加速寿命试验下指数分布的mle存在和唯一的一个充要条件，并用随机模拟的方法研究比较了参数估计的优良性，最后给出了p组序进应力加速寿命试验下weibull分布中参数的点估计和区间估计，讨论了有关问题，给出模拟实例。
