Mandarin:
自动加速 (zì dòng jiā sù)

Explanation in English Language (EN):
Autoacceleration, also known as the Trommsdorff effect, is a phenomenon where the rate of a polymerization reaction increases as the reaction progresses. This occurs because the increasing viscosity of the reaction mixture hinders termination steps, leading to a buildup of reactive species and a rapid increase in polymerization rate. This effect can be significant in bulk polymerization and can lead to uncontrolled exothermic reactions.

Explanation in Mandarin (ZH):
自动加速，也称为 Trommsdorff 效应，是一种现象，其中聚合反应的速率随着反应的进行而增加。发生这种情况是因为反应混合物粘度的增加阻碍了终止步骤，导致活性物质的积累和聚合速率的快速增加。这种效应在本体聚合中可能很显着，并可能导致不受控制的放热反应。
