| 摘要: |
| 本文分析影响被炸药驱动下抛板极限速度的重要因素， 讨论了一些经验公式的适用范围；提出了根据二维抛板的数值计算得到的两个重要规律：①在炸药与抛板的质量比相同的情况下，抛板的极限速度之间具有一定的相似关系；②修正的古尼公式可用来计算二维抛板的极限速度。 |

| Abstract: |
| The important factors to affect the limit speed of a projected plate driven by explosive are first analysed in this paper. This analysis is combined with a discussion about the range of application of the empirical formulae. Then two important laws，which are summarized from the results of the numerical computations to two-dimensional projected plate，are formulated: ①When mass ratios of explosive and projected plate are the same，there is a certainly similar relation among limit speeds of two-dimensional projected plate；② The revised Gurney Formula may be used to calculate the limit speed of two-dimensional projected plate. |
