摘　　要：该实验探索建立差示扫描量热法鉴别珍珠粉和贝壳粉真伪。使用密封式铝坩埚封装样品,测定条件为升温速率10℃·min^(-1),样品量3 mg,氮气流速为40 mL·min^(-1)。结果表明珍珠粉及贝壳粉热焓值具有明显差异。该法可用于珍珠粉及贝壳粉鉴别,方法操作简便、结果准确。The paper is aimed to establish a methods for identication of pearl powder and conch powder from different origins. Her- metic aluminum pan was used to encapsulate samples. The optimal testing conditions were： heating rate 10℃ · min-1, sample weight 3mg and nitrogen gas flow rate 40 mL · min-1 The enthalpy values of pearl powder and conch powder was obvious different. Identica- tion of pearl powder and conch powder by DSC is a practical method for its accuracy, convenience and practificality.
