natural circulation

基本解釋

One is the slightly boiling, natural circulation Shell type water reactor.
一種是微沸騰殼式自然循環(huán)供熱堆；
They got rid of those and they're using natural circulation to cool the core, again more passive.
他們除去了那些,他們在使用一個自然的再循環(huán),來將核心冷卻，還是更被動的。
Fouling removing or preventing evaporator of natural circulation is ideal to solve the fouling problem.
自然循環(huán)自動清洗式蒸發(fā)器是解決蒸發(fā)器結垢問題的理想方案。

If spaces designated for casual interaction are visually isolated or not along natural circulation patterns then it is difficult to casually use them.

The discovery that animals in pristine environments have few bacteria with resistance genes makes it likely that much of the antibiotic resistance found in these other species is a result of human influence, rather than natural gene-circulation.

自然循環(huán)
Both the similarity criteria of singlephase and two-phase natural circulation can be preserved and there is no obvious scaling distortion due to the transition of the scaling ratios. However,the cost of this kind of facility will be high.
結果表明:采用小尺度、等壓力、同工質的實驗裝置模擬實際系統(tǒng)自然循環(huán)現象更為準確實際,單相和兩相自然循環(huán)比例準則可同時滿足,不存在復雜比例變化帶來的失真,不利因素是試驗成本偏高。
