使用直径为2.5mm的铂坩埚,在地面和空间进行了四硼酸锂（LBO）晶体材料的融解结晶实验,测量了高温熔体内的温度分布,在简化条件下根据热传输方程和扩散方程求得的计算值与实验值基本一致.在地面熔体内温度分布的变化较大,在空间环境中熔体内温度分布趋于平稳.在两种状态下熔体内同一位置的温度偏差不超过8℃.
A 2.5 mm diameter platinum crucible was used to melt and crystallize lithium tetraborate (LBO) crystal material on the ground and in space. The temperature distribution in the high temperature melt was measured. Based on the heat transfer equation and the diffusion equation The calculated values are in good agreement with the experimental values, and the temperature distribution in the ground melt changes greatly, and the temperature distribution in the melt tends to be stable in the space environment. The temperature deviation in the same position in the melt does not exceed 8 ° C.
