In the below room temperature test, opening the refrigeration apparatus also switch, automatic temperature and the set temperature range constant.

在进行低于室温的试验时，打开制冷开关，仪器也同样进行自动控温并在设置的温度点范围内恒定。

However, disturbances from inside and outside of the constant temperature room, such as infiltration air, the equipment radiation fluctuation will affect the temperature stability.

而恒温室内外扰量多有渗透风、设备散热量波动等，导致了其恒温稳定性很难达到预期效果。

Unlike large glass mirrors which are subject to the vagaries of humidity, thermal dynamics and constant deformation from gravity itself, liquid mercury which remains molten at room temperature can reflect as much as 75 percent of incoming starlight with little of the fuss associated with large conventional mirrors.
