As the transient parameters during thrust termination of SRM with four reverse nozzles are determined by identification techniques and considered as random variables which obey normal distribution, the interior ballistic dispersion during thrust termination can be analyzed by Monte Carlo method.

用辨识方法确定了带反喷固体火箭发动机推力终止过程中的瞬变参数，视这些参数是服从正态分布的随机变量，用Monte Carlo方法分析了推力终止过程内弹道的散布。

With a transmission capacity of four million kilowatts, the line stretches across 80 cities, delivering power from the Belo Monte hydroelectric dam to economic centers in the southeast like Sao Paulo and Rio de Janeiro.

线路途经80个城市，输电能力400万千瓦，将电力从贝罗蒙特水电大坝输送到巴西东南部的经济中心地区，如圣保罗和里约热内卢。
