| 摘 要： | 根据ＺＬＣ法测定晶内扩散系数的基本原理，建立了测量误差与参数Ｌ、吸附质最低检测浓度及其精度的理论关系。结合环己烷在ＨＺＳＭ－５、Ｈβ和ΗＹ中扩散系数的测定结果，讨论了为满足ＺＬＣ的基本假设和提高测量精度在试验技术上应注意的问题，并指出了这一方法的应用范围

| Abstract: | The measuring error of ZLC method is theoretically related to the parameter L and measuring accuracy of the adsorbate concentration based on the principle of the method In order to meet the needs of ZLC principle and enhance the measuring accuracy,the points for attention in measurement have been demonstrated with the desorption results of cyclohexane in HZSM 5,Hβ and HY It should be pointed out that the measuring range of ZLC method should be limited to the system of D/R 2<0 01 |
