From then on the growing sphere is just lithium phosphate and, by manipulating the conditions, the researchers were able to make the coating glassy rather than crystalline.

至此开始形成的就只会是锂磷酸铁，通过控制环境，研究人员能够使球体表面为玻璃质而非晶质。

The idea that stars were fixed in some crystalline sphere that rotates around the world , once you look at that kind of depth, becomes less plausible .

那些星体组合成水晶般的缎带,环绕着世界做旋转运动，只要看一看那条缎带的宽度，马上你就会瞠目结舌。

The outer most crystalline sphere consists of fixed stars and these rotate around us which is why we see the stars moving in the sky.

外部的圈层则由星星组成,它们围绕着我们旋转,这就是为什么我们看到的星星会在天空中移动。
