The overcooling phenomena are very common in inorganic thermal storage materials.This paper mainly studied the overcooling phenomena of dibasic sodium phosphate. 摘要 針對磷酸氫二鈉的過冷進(jìn)行研究，加入適量的成核劑降低其過冷度。

Overheat or overcool of the engine would result in the power decrease, severe wear of moving parts and iscrease of fuel consumption. 若發(fā)動機(jī)過熱或過冷，就會導(dǎo)致發(fā)動機(jī)功率下降、加劇運(yùn)動件的磨損及燃料消耗增加等。

The solidification process of liquid steel is forming and growing pro cess of crystal nucleus,and formation of crystal nucleus depends on overcooling degree and solid particles in liquid steel. 鋼水的凝固過程是晶核的形成及長大過程，而晶核的形成則依靠鋼水的過冷度和鋼水中的固體質(zhì)點(diǎn)。

In the view of the overcooling of the condensate in the dehydrating column,the rise of pressure was not due to the insufficient condensate.The main reason of continuous blowdown from rectifing col... 從脫水塔塔頂冷凝液過冷現(xiàn)象認(rèn)為壓力升高與冷凝能力無關(guān)，指出不凝氣積聚是導(dǎo)致精餾塔持續(xù)放空的主要原因。
