摘要: 在爆轰法合成超细金刚石中，利用马赫效应提高金刚石得率。用Whitham方法计算马赫杆上的爆轰参数。实验采用中间为TNT药柱、外边包裹TNT/RDX（30/70）的装药，在爆炸罐氮气介质中爆炸，超细金刚石得率为6%，包裹盐后得率超过10%。Abstract: This paper proposes a method to use Mach effect in explosive detonation to enhance the yield of ultrafine diamond. The detonation parameters on Mach rod were computed by Whitham method. The cylindrical charge in experiment was TNT wrapped with TNT/RDX (30/70) charges. Ultrafine diamond can be obtained from the soot of detonation product in a nitrogen-filled chamber, the yield is 6%; if this charge is wrapped with salt, the yield can be more than 10%.
