The reaction is an exothermic reaction, its structure transition state occurs after energy transition state.

该反应为放热基元反应，其结构过渡态出现在能量过渡态之后。

Structure transition state occurs before energy transition state in endothermic reactions, structure transition state occurs after energy transition state in exothermic reactions.

一般来说，放热基元反应，结构过渡态出现在能量过渡念之后，吸热基元反应结构过渡态出现在能量过渡态之前。

Russia and Iran are both believed to have renewed their commitment only to allow Bashar al-Assad to go as part of a balanced orderly transition that would retain much of the regime structure and state institutions.
