研制了一种用于瞬态扩散场测量的高精度干涉仪系统。该系统由快速传热控制系统和实时相移干涉仪组成。传热控制系统有一个小型试验室，其中液体温度由非平衡热电装置控制。为了研究无双扩散对流的纯扩散场，进行了飞机微重力实验。利用该系统测量了NaClO3和Ba（NO3）2水溶液的热扩散场和质扩散场。热和质量扩散场进行了研究与各种温度条件。观察了双扩散对流对扩散场测量的影响。在常压和微重力条件下，测量了不同温度梯度下NaClO3溶液的质量扩散。研究了晶体生长与过冷度的关系，发现在过饱和度较小时，没有晶体生长。这一结果与小型火箭实验的结果一致。
A new measurement system for investigation of transient diffusion fields using an accurate interferometer system was developed. This system was composed of a rapid heat-transfer control system and a real-time phase-shift interferometer. The heat-transfer control system had a small test-cell in which the liquid temperature was controlled by non-equilibrium thermoelectric device. In order to investigate pure diffusion fields without double diffusive convection, micorgravity experiments using an airplane were carried out. Thermal and mass diffusion fields of aqueous solutions of NaClO3and Ba(NO3)2were measured by the system. Thermal and mass diffusion fields were investigated with various temperature conditions. The effect of double diffusive convection on the measurement of diffusion fields was observed. Mass diffusion of NaClO3solution in various temperature gradients was measured in normal and micro-gravity conditions. The relation between crystal growth and super cooling was investigated, and no crystal growth was observed at small supersaturation ratio. The result agreed with that obtained using a small rocket experiment.
