adj.不活潑的；慣性的

The joy on my face cannot call in temporarily because of inertial action, still continueing absently so. 我臉上的快樂因慣性的作用一時無法收回，所以仍茫然的延續(xù)著。

Inertial cavitation is the process where a void or bubble in a liquid rapidly collapses, producing a shock wave. 慣性的氣穴現(xiàn)象是指在一種液體中空穴或者泡沫迅速地破裂，生產(chǎn)沖擊波。
