Abstract : from the point of theoretical analysis , this dissertation provides the coupling calculation on the hot gas temperature field and ablation in the cavity between stress release boot and insulation of solid motors . through the calculation , some law of the ablation of the stress release boot is found 文摘:从理论分析的角度出发，通过对人工脱粘层和绝热层所构成的槽缝燃气温度场与烧蚀的耦合计算，得出了人工脱粘层的烧蚀规律。
Abstract : during the measurement of optical nonlinearities of sample in the thin film by z - scan technique , ablating makes a hole in the thin film if the incidental laser power is too high , that will produce the error to measurement results 文摘:用单光束扫描法研究薄膜材料的非线性光学性质时，如果入射样品的激光功率过大，将会烧蚀薄膜而产生孔洞，虽然其归一化透过率曲线类似于没有烧蚀的情况，但与样品的非线性光学性质无关，因而造成测量结果错误。
To find the ways to increase repetition rates and lifetime of the switches , mechanisms of two physical processes which determine repetition rates and lifetime of the switches , dielectric recovery and electrode erosion , were studied in theory , and a serial of high - energy high - coulomb repetitive experiments were performed with two different three - electrode gas spark switches designed by ourselves 为了探寻提高开关重复频率和寿命的技术途径和方法，对制约开关重复频率和寿命的两个主要物理过程?绝缘恢复和电极烧蚀的机理进行了理论研究。设计了两种形式的三电极吹气式气体火花开关，并进行了高能、大电荷量重复频率实验研究。
By observing the macrocosmic and microcosmic state of the test specimens , the ablation pattern of inhibitor was put forward and ablation mechanism was analyzed . the critical average particle diameter that influenced inhibitor ablation was obtained . the time - dependent ablation expression associated particle concentration and angle was achieved through analyzing their variation alone with the change of specimen figure ( 4 )通过对试验后绝热材料试件的表观和微观状态分析，提出了过载条件下绝热层的烧蚀模式，并分析了其烧蚀机理，获得了试验条件下影响绝热层烧蚀的平均颗粒直径。
