The gasochromic processes of switchable mirrors based on a Mg–Y alloy were studied by measuring the change in volume concentration (vol%) of H₂ in the air gaps of a mirrored cell using a residual gas analyzer. The change in the optical transmittance of the mirrors and the relative humidity in the gaps during the processes were measured simultaneously. An important factor for developing a practical switching system, which helps realize a fully hydrogenated state without water condensation, is to control the vol% of H₂ in the air gap to be 1.0%.

可切换反射镜气致变色过程中的气体和湿度分析

通过使用残余气体分析仪测量镜面电池气隙中H _{2 的}体积浓度 (vol%) 的变化，研究了基于 Mg-Y 合金的可切换镜的气致变色过程。同时测量镜面透光率的变化和间隙中的相对湿度。开发实用的开关系统的一个重要因素是控制气隙中 H ₂的体积百分比为1.0% ，这有助于实现完全氢化状态而不会出现水冷凝。
