In chapter2 , we discuss the step - stress accelerated life test . under typei and typeii censoring of data from the exponential distribution , we first present a necessary and sufficient condition for the existence and uniqueness of the maximum likelihood estimators of the parameters for the distribution , then give two confidence intervals based on the mle . finally , we compare them with results obtained in [ 8 ] by using monte - carlo simulation
本文第二章首先给出了指数分布场合下步进应力加速寿命试验定时和定数截尾的mle的存在和唯一的充要条件，然后给出了正常应力下平均寿命的近似置信区间，最后用随机模拟的方法研究了mle的点估计的偏性和均方误差，近似置信区间覆盖真值的比率并与其它方法作了比较。
There are several problems in scalable and reliable multicast , such as , feedback implosion and local recovery , etc . aim at to solve the problem of feedback implosion , we discuss carefully how to set the timer to avoid the nack implosion in receiver - initiated , integrate fec system . we propose two methods : divided time equally and based on exponential distribution to set timers , divided time unequally and based on exponential distribution to set timers . by analyzing for up to 10 receivers , both of them can avoid the nack implosion and feedback delay due to timers is low
在可伸缩可靠多描通信中存在反馈信息爆炸、局部恢复数据困难等问题，为了解决反馈信息爆炸的问题，本文针对基于接收者启动、使用集成fec的系统，详细讨论了如何使用定时器避免nack爆炸，提出了设置定时器时间的两种方法：基于指数分布、均匀分段方法和基于指数分布、非均匀分段方法，并且分析了它们抑制nack的能力和由定时器引起的nack延时长短，通过分析可知：对接收者数量达到10 ~ ( 10 )数量级的多播通信，这两种方法都能避免反馈信息爆炸，且由定时器引起的nack延时短，并且后一种方法优于前一种方法。
