- pulsed envelope principle 脉冲包络原理
- With such short pulses, it is important to be able to control the precise relation between the individual oscillations of the electric field (the carrier wave) and the pulse envelope. 脉冲这麽短时，精确控制电场（载波）的单一振荡和脉冲包络线之间的关系就显得很重要。
- In accordance with the measuring method for rounded shape,by using minimum enveloping principle,the outlining parameters of polygon and errors are evaluated. 由于其数学模型的求解过程是一个多目标优化的复杂过程,所以采用了遗传算法对该数学模型进行了求解。
