Following the G7 meeting on Tuesday, president Zelensky called for the West to help Ukraine create an air shield against Russian missiles.

继周二的七国集团会议之后，乌克兰总统泽伦斯基呼吁西方帮助乌克兰建立一个防空系统，以对抗俄罗斯导弹。

All of it is wrapped in a thin layer of air, shielding its surface from the harsh radiation and cold vacuum of space.

所有一切被包裹在一层薄薄的空气层中，保护它的表面，隔开严酷的辐射和寒冷的真空。
