To investigate the gas-surface interaction on non-metal surfaces widely used in the micro-technology, a novel measurement system for the thermal accommodation coefficient, which represents energy transfer between gas and surface, was proposed. Even though there were some troubles on a molecular beam scattering experimental apparatus, numerical analyses by the molecular dynamics method gave a qualitative characteristics on the gas-surface interaction. By setting appropriate conditions obtained from the numerical results, the successive measurements will lead to the understanding on characteristics of the interaction.

为了研究在微技术中广泛应用的非金属表面上的气体-表面相互作用，提出了一种新型的表征气体与表面之间能量传递的热适应系数测量系统。尽管分子束散射实验装置出现了一些故障，但用分子动力学方法进行的数值分析给出了气体-表面相互作用的定性特征。通过设置由数值结果获得的适当条件，连续的测量将导致对相互作用特征的理解。
