摘　　要：热孔计法(TPM)是表征孔结构参数的一种方法,利用受限空间液-固相转变温度的变化程度,推算材料中的孔径尺寸、分布、孔体积和比表面积等一系列孔结构参数,适合测试1~100 nm范围内的微孔尺寸。但是,TPM作为测试孔结构参数的相对方法,测试方法、测试条件和分析计算都会影响到最终结果的可靠性,因此文章详细阐述了TPM的计算理论、相关参数的确定、测试方法、影响因素以及数据处理方法。Thermoporometry(TPM)is a method to characterize the pore structure parameters including pore size and distribution,pore volume,specific surface area and so on based on the change degree of liquid-solid phase transition temperature in confined space,which is suitable for the pore size in the range of 1~100 nm.However,TPM is a relative method for the pore structure characterization,the test method,test conditions,analysis and calculation methods will affect the reliability of the final results.Therefore,the calculation theory,determination of related parameters,test methods and influencing factors,and data processing methods of TPM were reviewed in detail.
