Translation of "criticality" into Chinese

Nuclear reactors shall not be made critical before they have reached their operating orbit or interplanetary trajectory;

核反应堆在达到工作轨道或行星际飞行轨道前不得使其进入临界状态。

Trans-critical systems have proved to be effective, economical and energy-efficient, and hundreds have been installed.

实践证明,跨临界制冷系统经济有效、节能高效。 丹麦已安装数百个跨临界制冷系统。
