摘　　要：本工作对Schorlander和Douglas的微量气体吸收器从结构和操作方法上加以改进,使其不仅保持了试剂用量少、测量迅速、精确、操作简便的特点,而且扩大了所适用的溶剂范围,并可应用于混合溶剂系统。用此装置测定了氢气在丙酮+水+MIBK三元混合溶剂中,25～55℃的溶解度数据,取得了满意的结果。The microgasometer, originally developed by Scholander and modified by Douglas, was improved in its structure and operation. The now apparatus not only remains its merits of simple, accurate, fast, and using a little sample, but also is applied to more solvents and mixture solvents. The solubility data of hydrogen in acetone+water+4-methyl-2-pentone ternary mixture solvent were measured at 10℃ intervals from 25 to 55℃. The results are satisfactory.
