斜波发生器的设计准则

Design Criterion for Ramp Wave Generator

摘要: 导出了斜波发生器的设计准则，它可表示为-[(2/3)+(g/2)]，或者为-[(2/3)+(g/2)](cV/c2)（为Grneisen系数，热膨胀稀疏，cV定容比热容，c流体力学声速，g材料系数）。对一种微晶玻璃的实验测量结果表明，它可用做斜波发生器，在其厚度为20.39 mm时，可以把冲击波改造成上升时间约800 ns的加速度波。

Abstract: A design criterion for ramp wave generator is derived in this paper, which may be expressed as -[(2/3)+(g/2)] or -[(2/3)+(g/2)](cV/c2) (here is Grneisen coefficient, thermal expansion coefficient, c hydrodynamic sound speed, cV specific heat capacity at constant volume, g a material constant). Experimental results of a glass-ceramic sample showed that it may be used as a ramp wave generator, in which a shock wave could be transformed to an acceleration wave with front rise time of 800 ns at the position of 20 mm thickness.
