| 摘 要： | 在微重力条件下,表面张力成为液体流动的主要驱动力,毛细现象更为显著。我们将铟、镉试样封装在石英试管中,在卫星自由飞行期间加热熔化井缓慢冷却后,考察铟、镉之间以及它们和石英玻璃之间的润湿行为和其他一些表面现象。分析认为:铟在地面和石英玻璃是润湿的,铟、镉是互溶的。但在微重力条件下,铟和石英玻璃不润湿,在试管中形成一小球。我们对铟球的半径、圆度作了测量,对圆度偏差及其产生原因进行了初步探讨。

| Abstract: | Surface tension is important power for liquid in space microgra-vity.Indium and Cadmium was sealed in quartz glass tube,heated and thencooled slowly.We have studied Indium-Cadmium quartz glass wetting propertyand other surface phenomenon.Indium can wet quartz glass and Indium candislove Cadmium in the earth,but Indium can not wet quartz glass and In-dium-cadmium turn into two spheres in space microgravity.We measured theradii and sphericity of Indium sphere. |
