摘　　要：本文介绍了一种简单的小样品比热测量法．通过引入一种新的量热器，可以用弛豫法测量几十毫克小样品的热容．测量温区为１．２Ｋ～１５Ｋ．目前有优于１０％的精度．Abstract A simple way of measuring specific heat of small samples is described. After Introducing a new kind of calorimeter, we find an easy way to measure heat capacity of small samples about a few tens milligrams using relaxation methods in the temperature range of 1. 2 to 15K. At Present, the accuracy is better than 10%.
