为研究物质在低温下的光学性质,我们在G.H.Lesch等人[1]设计的低温光学实验用恒温器的基础上作了改进,设计了一具光学和电学实验用低温恒温器(图 1).既保持了[1]中恒温器的结构简单的优点,又提高了恒温精度,还使样品能在光路中作适当调节. 样品架由整块黄铜做成(图2).它具有较 In order to study the optical properties of matter at low temperature, we have improved on the basis of the low temperature optical experiment thermostat designed by GHLesch et al. [1], and designed a cryostat for optical and electrical experiments (Figure 1) While maintaining the simple structure of the thermostat in [1] and increasing the thermostat accuracy, the sample can be properly adjusted in the optical path. The sample holder is made of one piece of brass (Figure 2)
