rectangular pulse
Examples
- The calculated results show that , for low energy protons ( energy less than several decade mev ) , the contribution of proton nuclear reaction to energy deposition can be neglected ; while for high energy protons ( energy greater than several hundred mev ) , the great difference appears for the above two cases . this gives us an indication that the contribution of proton nuclear reaction to the energy deposition must be concerned for high - energy protons . the propagation process in material of thermal shock wave induced by high - energy intense - current pulsed proton beam irradiation is calculated for several different proton energies
对于入射能注量为418 ( j cm ~ 2 )脉冲宽度为0 . 1 s的矩形脉冲强流质子束，计算结果表明，由于质子束能量不同，引起的初始热激波( 0 . 1 s时刻的热激波)有单峰结构，也有双峰结构，不同能量的强流质子束引起的热激波在传播的过程中都会出现明显的弹性前驱波。 - We use this conclusion in our program . the last , the principle and the precision of the detection of range , speed and angle is analyzed and discussed theoretically . using the precision formula of rectangle pulse waveform , we programming the software to accomplish the computation simulations
