摘要

摘要: 在常温、实验压力为0～3 GPa条件下，利用脉冲反射法测量了纵波在碳化钨压钻中的走时，结果发现，随实验压力升高，碳化钨压砧的走时线性减少。碳化钨压砧被压缩是引起碳化钨压砧的走时减少的主要原因。实验压力（p/GPa）与碳化钨压砧走时减少量（t/s）之间的关系为：t=(0.022 330.000 81)p。运用这个关系式可以对所测量的岩石弹性波速度进行校正，以获得更为精确的岩石弹性波速度。

Abstract: Travel time in WC anvils was measured using pulse reflect method at room temperature and under cell pressure up to 3.0 GPa. Experimental results indicate that the travel time in the WC anvils decreased linearly with cell pressure. A possible reason for this result is that the anvil was compressed during loading. The relationship between travel time decrease (t/s) and cell pressure (p/GPa) is t=(0.022 330.000 81)p. Compressional wave velocity under high pressure can be corrected using this formula. As an example, compressional wave velocities under high pressure in three rock samples were corrected.
