In the paper, aiming at the structural characteristic and measuring requirement of bombcore, the laser scanning principle is adopted to measure several radial dimensions.
本文针对弹芯径向尺寸的结构特点和检测要求，采用激光扫描原理对其多个径向尺寸进行了检测。

The plot: When Mother Earth's molten core stops spinning for unknown reasons, a team of scientists must go to the centre and detonate a hydrogen bomb to get it to spin again.
In Chernobyl the explosion was caused by excessive pressure buildup hydrogen explosion and rupture of all containments propelling molten core material into the environment (a "dirty bomb").
