The probability of steam generator tube rupture (SGTR) during the operation of a nuclear power plant is high; there were some SGTR incidents happened during operating plants in the world.

对核电厂来说，蒸汽发生器传热管破裂(SGTR)事故发生的概率比较高，世界上现有核电厂发生过此类事件。

On defining relative size of rupture scales, a statistical result shows that it is of the lowest probability that ruptures with the same scale occur in two successive cycles.

根据定义的相对破裂规模，统计表明：两相继轮回的破裂规模相同的概率最小。
