摘　　要：以山东威海青皮无花果为试材,对其共晶点和共熔点采用电阻法进行测定,并对其测量数据进行曲线拟合,根据函数曲率的物理意义,分别计算得无花果的共晶点-28℃,共熔点为-24℃。Ficus carica L. from Weihai, Shandong, wasapplied as the experimental material. In the freeze-drying experiment, use resistance method to measure eutectic point and co-melting point temperature. All data was analyzed with curve fitting method. According to physical implication of function curvature, eutectic point and co-melting point of Ficus carica L. were calculated to be -28 ℃ and -24℃, respectively.
