摘　　要：本文叙述用差示扫描量热法测量新发现的有机非线性光学晶体——L-精氨酸磷酸盐(简称 LAP)的比热。为了提高测量的准确性,采用比例法。为了验证方法的可靠性,首先用该法测量石墨的比热,石墨比热的实测值与文献值相吻合。整个测量得到了满意的结果。This paper describes the measurement of specific heat capa-city of a new organic nonohydrate(LAP)by differential scanning calori-metry.The ratio method was adopted to improve the accuracy of measure-ments,In order to verify the reliability of this method,we first performedthe measurement of the specific heat capacity of graphite.The obtainedcorresponding values for graphite are in good agreement with those repor-ted in literatures.Satisfatory results have been obtained in all the proce-sses of measurements.
