The overcooling phenomena are very common in inorganic thermal storage materials.This paper mainly studied the overcooling phenomena of dibasic sodium phosphate. 摘要 针对磷酸氢二钠的过冷进行研究，加入适量的成核剂降低其过冷度。

Overheat or overcool of the engine would result in the power decrease, severe wear of moving parts and iscrease of fuel consumption. 若发动机过热或过冷，就会导致发动机功率下降、加剧运动件的磨损及燃料消耗增加等。

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. 钢水的凝固过程是晶核的形成及长大过程，而晶核的形成则依靠钢水的过冷度和钢水中的固体质点。

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... 从脱水塔塔顶冷凝液过冷现象认为压力升高与冷凝能力无关，指出不凝气积聚是导致精馏塔持续放空的主要原因。
