过冷现象

Another winter occurrence in and around Yosemite Falls is "frazil ice", a substance that forms in waterfalls and creeks when water becomes super cooled.

在约塞米蒂瀑布内和周围发生的另一个冬季现象就是"水内冰"，这是一种当水达到过冷状态时在瀑布和溪流中形成的物质。

One, two and three recalescence events in the solidification of highly undercooled Ni_(68)B_(21)Si_(11) alloy melt and the conditions of undercooled together with the effect on solidification morphologies were revealed.

发现深过冷Ni_(68)B_(21)Si_(11)合金液形核过程中的多次再辉现象，揭示了二次和三次再辉的过冷条件，以及对凝固组织的影响。

By the supercooling of the lava when it hits the water.

熔岩碰到水之后的"过冷现象"。

Plots of molar volume verses temperature are linear for all samples in the stable liquid region, but there is an increase in the slope〓 with decreasing temperature in the supercooled liquid region, analogous to that observed for C〓 in similar alkali titanosilicate liquids.

将摩尔体积对温度作图，在稳定的液体区内两者为线性关系，随着温度的降低到达过冷液相区，摩尔体积对温度的斜率升高，类似于在相近的碱硅酸盐熔体中观察到的热容的异常现象(Richet and Bottinga，1985；Lange and Navrotsky，1993；Tangeman and Lange，1998)。

Duplex cold crystal peak was also observed in the DSC of PET by vapour of unactive solvents.

双冷结晶峰现象在一些非反应性溶剂处理过的PET试样的DSC曲线也观察到。

The experiment results show that chocking occurs when downstream pressure decreases below the saturation pressure corresponding to upstream temperature and the mass flow rate of refrigerant becomes almost independent of downstream pressure.

试验结果表明，当节流短管的下游压力小于上游温度所对应的饱和压力时，制冷剂出现壅塞现象，此时制冷剂流量不再受下游压力变化的影响；上游压力、上游过冷度、短管直径对制冷剂流量的影响较大。

Because of the melt property, the process of phase change is stable and controllable, the phase detaches will not happen easily.

这种熔融峰特征，使材料的相变过程较为平稳和可控，不易出现过冷现象和相分离。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
