That gradient further affects the feed rate by cooling the barrel in the location where it's critical to develop solids feeding, solids-bed compaction, and heat to initiate melting.

通过在某个地方冷却筒体，而这个地方是建立固体喂料、固体床，进而开始熔融的地方，这个梯度就这样进一步影响喂料速率。

Ro systems remove a large percentage of the total dissolved solids, as well as bacteria and endotoxin, from the feed water.

RO系统去除了给水中大百分比的总溶解固体，还有细菌和内毒素。

It's much easier to feed them solids when they are somewhat able to support themselves.
