軍用高能材料.安全性和易損壞性.直徑62mm聚能炸藥噴口The main researches were as follows : by the underwater test results of condensed explosive, the optimized test conditions and the several calibration parameters for energy calculation were determined in a small pool
通過對凝聚相炸藥水下爆炸能量的測試，確定了在小水池中測試炸藥能量的最佳條件及能量計算的修正參數。( 3 ) principle analyse produce powder bag stress produced to explode involve and produce and catch gas can cut function mechanism that crack expand further gathering mainly according to fracture mechanics
（ 3 ）根據斷裂力學原理分析了主爆藥包爆炸產生的應力波及爆生氣體對聚能切割裂隙進一步擴展的作用機理。The results at normal temperature have shown that klc of high polymer bonded explosive are very low comparing to metals and some high polymer materials, thus the ability of pbxs to resist crack expanding is very poor, and once some cracks occur inner a structural part of pbxs, the structure will fail very soon and easily. so in the process of machining and production, cracks should be avoided carefully in pbxs parts. some important laws about klc of the three typical pbxs above changes with temperature have been obtained as follows : a
對三種具有代表性的高聚物粘結炸藥j1 、 j2和j3在常溫下的平面應變斷裂韌度進行了測試與研究，研究結果表明：相對于金屬及某些高分子材料而言，高聚物粘結炸藥的k _ （ ic ）值很低，即高聚物粘結炸藥的抗裂紋擴展能力是極差的，一旦炸藥構件中產生了裂紋，炸藥構件將極易破壞，因此，在高聚物粘結炸藥構件的生產及加工過程中，應避免裂紋的產生。Klc of j3 is higher than j2 and j1 at different temperatures, and this shows the stronger ability of j3 to resist crack expanding. two probations have been tried to explore the reasons concerning the results above, one of which is by analyzing the compositions of the three pbxs above and shows that the stronger ability of j3 to resist crack expanding is probably mainly due to the use of bonder b2, and another is by using scanning electronic microscope sem to observe the fracture face morphologies of the specimens at different temperatures. the quantitative observations strongly support the laws of klc of pbxs changes with temperature is revealed as follows : a
測試了三種高聚物粘結炸藥在不同溫度下的平面應變斷裂韌度k _ （ ic ）值，得到了這三種炸藥的平面應變斷裂隨溫度的變化規律： a 、隨著溫度的增加，高聚物粘結炸藥的平面應變斷裂韌度降低； b 、在45以後j2的平面應變斷裂韌度降低最快，在60時已很差，比j1還低，可以認為j2在高溫下的抗裂紋擴展的能力比j1還差； c 、在不同溫度下， j3的平面應變斷裂韌度比j2和j1的均高，表現出相對較強的抗裂紋擴展能力。So it has especial characteristics in studying nuclear weapon - related hydrodynamic problems, which ca n ' t be replaced by others research methods
因此電磁內爆技術在高能量密度研究領域具有獨特的優勢，是炸藥爆轟和激光聚變不能代替的。分享友人
