| 摘要: |
| 本文给出了在滑移爆轰波作用下二维金属平板抛掷的理论模型(模型分为真空中抛掷和空气中抛掷两部分)及其计算方案。作者按特征线差分方法设计了程序，上机进行了计算，将其计算结果同实验数据、经验公式做了对比，从而得出一些结论，主要有：①理论模型与实际基本相符；②对于抛板的极限速度而言，当爆轰产物的绝热指数为3时，二维抛掷的计算结果同一维抛掷的公式给出的结果基本一致；③对于抛板的极限速度而言，从理论上算出：空气对抛板的速度影响不大，因此计算抛板的速度可不考虑空气的影响。本文同时根据理论的结果对于常用的经验公式以及它的改型进行了分析和评论。 |

| Theoritical Computation of the Two-dimensional Plate Projection Under the Action of a Sliding Detonation Wave |
| LYU Hongsheng |
| Abstract: |
| This artic1e gives not on1y the theoretical models of the theoretical computation of the two-dimensional plate projection under the action of a sliding detonation wave (the models are devided into two parts-the projection in vacuum and the projection in air) but also their computation schemes. Author designed the programs in accordance with the difference method of characteristics. Numerical calculations have been carried out on the electronic computer. The calculation results have been compared with the experiment data and empirical formula. Thus，some conclusions are obtained，the main points of them are：①The theoritical models mainly coincide with the practice; ③Concerning the limit velocity of the projected plate，the calculation results obtained in two-dimensional model coincide with the results calculated in one-dimensional model when adiabatic exponent of the detonation product is equal to three; ③With regard to the limit velocity of the projected plate，the theoretical calculation results have showed that the effects of air on the velocity of the projected plate are negligible. For this reason，when the velocity of the projected plate is calculated，the effects of air on it can be ignored. Furthermore，in this article the analyses and the comments on the usual empirical formula and its modification carried out the basis of the calculation results. |
