【摘要】 介绍了采用直接测量特定时间间隔系列和微型红外通光式传感技术的探头原理，在“闪光二号”电子束装置上进行的喷射冲量随不同材料和不同能通量而变化的实验研究。实验结果表明，在能通量大体相同时，Ａ和Ｂ这两种特种材料的喷射冲量耦合系数分别只有ＬＹ１２铝的１／３和１／２左右。这说明此两种特种材料在受辐照条件下具有良好的降低喷射冲量的性能更多还原

【Abstract】 In this paper,the experimental studies of variation of blowoff impulse with different materials and different energy fluxes are described.The experiments are conducted on “FLASH Ⅱ” electron beam equipment with the probe principle of directly measuring the specific series of time intervals and miniature transducing technique passing infrared ray.The experimental results show that the coupling coefficients of blowoff impulse for two specific materials only is 1/3 and 1/2 or so of those of LY 12 aluminum alloy,respectively,in about the same energy fluxes.This shows that the two specific materials when they are radiated possess good property which can reduce blowoff impulses.更多还原
