So this identifies a number of thermal neutrons absorbed in control rods and water and that's sort of the thermal utilisation.

所以，这个确认了很多的吸收的热量中子，在控制棒和水里，那差不多是热能使用。

The number and spacing of the rods controls how light reflects which produces different colors.

杆状细胞的数目和间隔决定了如何地反射光，因而产生了不同的颜色。

It provides a reasonably and completely theoretical basis for combination of rods, centralizer, assembling site and number of depart device.

为抽油杆柱组合、扶正器、防脱器安放位置及数量设计提供了更加合理、完善的理论依据。
