解釋
選擇試驗-
? by comparing the experimental data with the modeling results, it was found that the he in the projectile produces reaction after considerably long time. and the expansion velocity of the shell is about one hundred meters per second, far below the velocity driven by detonation ( about 2000m / s ). ? the post - test recovered fragments prove that the reaction violence remains on low level
?通過試驗結果和數值模擬的殼體邊界和徑向膨脹速度的對比分析,發現帶炸藥彈體在以120m s左右的速度撞擊鋼靶后,經歷了相當長時間后才產生反應,且此時殼體的膨脹速度僅在百米每秒的水平,遠低於爆轟驅動下能達到2000m s左右的速度。
