When the laser trap was turned off and back on again, the ultra-cooled gas oscillated like a jelly sphere.

当激光阱被不断地关闭开启时，超冷气体像一个疲软的球体一样振动起来。

From the observation through optical microscope, it could be found that size became smaller and the crystal shape tended to the sphere after GAS.

用光学显微镜对超临界技术处理前后的粒径和晶形进行了观察，发现经过处理后的粒径变小、晶形趋于球形。

In recent years, an increasingly confident Moscow has used Gazprom to assert its authority over Russia's former sphere of influence by offering heavily subsidized gas to ex-Soviet countries such as Ukraine and Belarus.
