Abstract: In this paper, a new method, general reciprocal method(GRM), is used in interpretation of P_g wave data along HQ-13 line in Jiangsu Province. By the GRM method, wave data are firstly processed on microcomputer and then interpreted. The procedure is more fast and more effective than traditional method. The result of processing of drill data comfirms that the GRM solution is more accurate than that of T_oT_p method.

摘要： 用一种新的折射解释法——广义互换法(GRM),对江苏HQ-13线P_g波资料进行了解释。GRM法打破了传统的解释程序,先用计算机处理,后解释,其结果既客观又省时,不但能显著提高经济效益,而且经钻井资料证明它的解比T_oT_p法更精确。
