The protect frame of marine optical instrument needs enough strength and small self-shield effect, which is somewhat conflicting.
海洋光学测量仪器的保护框架既要有足够强度,又要自屏蔽效应小,这是一对矛盾的要求。

The thermal neutron fluence subsidence factor measured is basically in conformity with the self-shield factor deduced from the report of the producer of the tube.
测量得到的热中子注量率沉降因子与根据生产厂家报告推出的自屏因子基本符合。

Not in a no gain since the shield, not to have a selfish self tired.
