| 摘 要： | 导出了斜波发生器的设计准则，它可表示为γ<-(2/3)+(g/2)]，或者为α<-(2/3)+(g/2)](cV/c2)（γ为Grüneisen系数，α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 γ<-(2/3)+(g/2)] or α<-(2/3)+(g/2)](cV/c2) (here γ is Grüneisen coefficient, α 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. |
