摘要

本文研究了氦气通过空心玻璃硅微球壁的渗透性，这种微球可用作气体流动膜。研究是在一个特殊装置中进行的，该装置用于测量氦气在给定压力和温度下的动力学吸附曲线。使用基于单分散分布的数学模型来逼近实验数据。获得的数据温度范围为 21.5-110.0 °C。在此温度范围内，确定了微球壁的氦渗透率和微球吸附氦的活化能。

Study of helium permeability for silica microspheres

This paper presents the study of permeability of helium through walls of hollow glass silica microspheres, which can be used as membranes for gas flow. The study was performed in a special setup for measuring the kinetic sorption curves for helium at given pressure and temperature. A mathematical model based on a mono-dispersion distribution was used for approximating the experimental data. The data was obtained for the temperature range 21.5–110.0 °C. The helium permeability of microsphere walls and the activation energy for helium sorption by microspheres were defined for this temperature range.
