高聚物粘结炸药 meaning in English
plastic bonded explosive
Examples
- Experimental investigation on the fracture character of pbx
高聚物粘结炸药断裂特性实验研究 - When temperature lower than 30 ? , the fracture mode of j2 and j1 is mainly breaking of crystal mode , and at temperature of 45 ? ,
本文从三种高聚物粘结炸药的组份及组份含量等方面对此规律性进行了分析与解释。 - Both breaking between crystal mode and breaking of crystal mode exist at the same time , and at temperature of 60 ? , breaking between crystal mode has played dominate role
本论文结合高聚物粘结炸药的成型工艺对这一规律进行了分析，同时还提出了提高不同高聚物粘结炸药力学性能的一些技术途径。 - 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
测试了三种高聚物粘结炸药在不同温度下的平面应变断裂韧度k _ ( ic )值，得到了这三种炸药的平面应变断裂随温度的变化规律： a 、随着温度的增加，高聚物粘结炸药的平面应变断裂韧度降低； b 、在45以后j2的平面应变断裂韧度降低最快，在60时已很差，比j1还低，可以认为j2在高温下的抗裂纹扩展的能力比j1还差； c 、在不同温度下， j3的平面应变断裂韧度比j2和j1的均高，表现出相对较强的抗裂纹扩展能力。 - 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
对三种具有代表性的高聚物粘结炸药j1 、 j2和j3在常温下的平面应变断裂韧度进行了测试与研究，研究结果表明：相对于金属及某些高分子材料而言，高聚物粘结炸药的k _ ( ic )值很低，即高聚物粘结炸药的抗裂纹扩展能力是极差的，一旦炸药构件中产生了裂纹，炸药构件将极易破坏，因此，在高聚物粘结炸药构件的生产及加工过程中，应避免裂纹的产生。
