It also had the most desirable ratio of upper to lower trapezius activation (0.9), meaning the lower trapezius was activated at a higher level than the upper trapezius.
The energy ofactivation is the minimum energy level that two colliding molecules must possess in order to undergo a given chemical reaction.
激活能就是使两个碰撞分子得以进行某特定的化学反应所必须具有的最低能级。

The result showed that the chemical reaction of microwave synthesizing nano-TiC is a zero level reaction, the kinetic equation of the reaction and the reaction's activation energy were confirmed.
