从理论上探讨了聚能穴参数与射流速度的关系。对不同装药结构的射流有效长度进行了对比试验，对聚能射流的失稳及其原因进行了分析，提出了在工程爆破中增加射流稳定性和完整性的措施，对聚能装药的应用有重要的理论价值和实践意义。
The relationship between the parameters of the converging cavities and the jet velocity is theoretically discussed. The effective length of the jets of different charge structures were compared and tested. The instability of the jets and the reasons for the jets were analyzed. The measures to increase the stability and integrity of the jets during blasting were put forward. Application has important theoretical value and practical significance.
