An animator will see the overlap on the girl's hand asthe mother smacks the lollypop into the air. An animator will see the frightened expression on the girl's face, or the way the monkey reacted to the whole thing, or the frozen moment in time when the lolly landed in Mom's hair and they both just freeze for an instant as they realize their situation.

一个动画师应该会看到当妈妈把棒棒糖拍打到空中时小女孩手的overlap，而且还应该看到小女孩脸上惊恐的表情，或者猴子对整个事件的反应，或者当棒棒糖粘在妈妈头发上时她们都僵住不动，认识到她们的窘境的凝固时刻。

Oh, don't, don't, please don't, shouted Edmund, but even while he was shouting she had waved her wand and instantly where the merry party had been there were only statues of creatures (one with its stone fork fixed forever half-way to its stone mouth) seated round a stone table on which there were stone plates and a stone plum pudding.

爱德蒙叫道，但就在他大声喊叫时，她已经挥动了魔杖，刚才一群动物欢宴的地方，立刻出现了一个个动物的石像(其中一只就永远举着石叉凝固在离嘴一半的地方)，围坐在一张石桌前，桌上是石盘和石头的葡萄干布丁。

After analysing the flight, cooling and undercooled solidification of multistage atomized droplets, this paper adopts Newtonial cooling, highly undercooled heterogeneous nucleation and steadystate continuous growth model to calculate and simulate numerically the thermal history of droplets and effect of main atomization process parameters during multistage atomization. The results indicated that large undercooling occur mainly during later stage of multistage atomization while recalescence and rapid quenching occur mainly during forced cooling stage.
