破片密度 的英文怎麼說
中文拼音 [pòpiānmìdù]
破片密度
英文
fragment density-
The experimental results show that the wave shaper can control the moving direction of the rod fragments after the warheads exploded and ensure the integrity rate of the rod and that there is a close relationship between the flight attitude and the positioned angle, which is mainly reflected by the rotation velocity of the rod
試驗結果表明：採用波形控制器可以較好地控制戰斗部爆炸后桿形破片的飛散方向，以及保證桿條的完整率；桿條的飛行姿態與放置角有密切關系，主要通過桿條旋轉速度表現出來。Through the statistic and analysis of rock core crack, sonic wave velocity test, microcosmic structure of core slice observation by electron microscope, core strength test to the sampled damaged slope rock mass, it indicates that the damage degree of smooth blasting to slope rock mass has no obvious relation with blasting scale but with the line density of explosive filling and the strength of the rock in damaged area decreases evidently
通過受損邊坡巖體取樣巖芯裂隙的統計分析、聲波速度測試、巖芯切片微觀結構的電鏡觀察及巖芯的強度試驗，發現光面爆破對邊坡巖體的損傷程度與爆破規模無明顯關系，而與光爆孔的線裝藥密度有關，損傷區巖石的強度明顯降低。Abstract : according to the fragment warhead of the missile, we propose dynamic characteristic of fragment dispersion in different reference frames, calculate dynamic distributing density function in earth reference frame and missile reference frame, and point out the dispersion section of the warhead is different from the dynamic distributing density in earth reference frame and missile reference frame
文摘:以某型防空導彈的破片殺傷式戰斗部為例，分析了在不同坐標系中的破片動態飛散特性，分別計算出在地面坐標系和彈體坐標系中破片的動態飛散密度函數，指出在不同的坐標系中戰斗部的飛散區和飛散密度不同。
