摘要
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℃.
The temperature distribution of the LBO melt, in space and on the ground, was measured with the control-temperature procedure on the loop-like Pt wire heater of diameter 2.5 mm of the space high temperature situ observation facility, and the related heat transfer and diffuse equations were used to certify theoretically experimental results. The temperature distribution in the melt in space, compared to that of group, tends to smooth. The temperature difference between space and group in the same place in the melt did not exceed 8°C.
