The adsorbent regeneration test showed that the active component was easy to run off at high temperature, so introducing active component again was needed for restoring its activity.
The material obtained by optical observation show that oriented clay film not only can be used in restoring rainfall, but also can used in restoring relative temperature.
微结构的观察还表明，光性定向粘土不仅可用于降水量的研究，也可用于指示温度的相对高低．。
