摘　　要：描述了一种联合使用锰铜计和康铜计间接测量柱对称滑移爆轰条件下，金属管内样品中冲击波压力的方法。给出了冲击压缩方法合成纤锌矿型氮化硼（ｗＢＮ）时的测量结果。结果表明：管内样品中压力范围大致在１１．５～２２ＧＰａ范围内，满足冲击波合成ｗＢＮ所需的压力条件；管内样品压力的发展变化具有不连续性。证明了这种间接测量管内压力的方法是可行的。The paper describes a methed to observe the pressure of powder samples filled in acylindrical metal tube which will be subjected to explosive compression. As an example, we mea-sured the pressure in the explosive shock synthesis of wurtzite-type boron nitride (wBN) fromgraphite-type BN. The results show that the shock pressure in the sample tube ranges from about11.5GPa to 22GPa (which satisfies the pressure condition required by the shock synthesis ofwBN) and that the pressure in the tube varies discontinuously. These experimental results indi-cate that this technique is feasible.
