Personally think that the first time in his place before the days of the best things to stay if not used, because two can play much on the attack, he had little chance to moonset, especially in such a restricted Wudang martial skills and more, so he used Pegasus飞瀑second, if spent immediately, this time also on the cooling down, and whether or not he did not bite on the run are chasing him, and if the time spent immediately on a drop-off, this time the situation must be cut West on the use of cooling, if not cooled quickly to their own on a few fresh, so down, it is estimated that more hope to win big.

个人认为在他放第一次天外之前最好别用呆若，因为两个远攻的打能放到他月落的机会不多，尤其是武当这样受制技能多的门派，所以等他用完第二次天马飞瀑，就马上呆若，这个时候月落也该冷却了，不管他上没上当都追着他跑，等呆若时间一过就马上月落，这个时候要是斩情决冷却了就用西子，要是没冷却就赶紧给自己清新几下，这样下来，估计赢的希望就比较大了。

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.
