shield-row tube

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。

Remove nuts attaching splash shield and caliper bracket to axle tube flange.

拆卸连接挡泥板和夹制器托架至车轴套管的螺帽.

It is indicated that the net thermal radiation loss from the outer surface of BASE tube may be less than 1W/ cm~ 2 if the structure of AMTEC is reasonable and several layers of thermal shield are fixed around the BASE tube.

结果表明，恰当设计AMTEC装置的结构，并在BASE管外加数层遮热屏，可使BASE管外单位电极表面的净热辐射损失在其工作温度范围内控制在1W/cm2以下。
