标 题: 怎么算Droplet的配分函数
发信站: BBS 未名空间站 (Tue Apr 2 00:03:04 2013, 美东)
各位物理高手，
我有一个统计力学的问题。就是怎么算Droplet的配分函数。也就是怎么算亥母霍
兹自由能。
（1）直接算，把3n个自由度分为，平动，转动。
（2）由热力学F=N•miu+sigma•A=N•miu+constant•N**（2/3)
我的问题是，这两种方法算出来的根本不一样，第二个里面有一个表面张力引起的n的2
/3次方，这个第一个方法里面好像没有。
到底哪种方法对。 |

What's the difference? Water vapor should be in molecular phase so it
increases RH directly. Water droplets evaporate firstly and become vapor.

发帖数: 286 | 23 没有在美国的婴儿奶粉厂参观过不是很清楚，但在国内的时候就学过，milk powder大
多数都是用spray drying，就是一个大stainless steel的罐子，从下面往上喷热空气
，从上面往下喷高速离心的液体奶，这样，液体奶的droplet很快就被烘干了，到
droplet掉到罐底时就已经成了粉末。因为罐体本身温度也很高，所以很有可能有液体
droplet被喷到罐身上，受热时间过厂而引起焦糖化反应（所谓的褐变）。这应该属于
产品本身的defect，但一般厂家在追求质量和效益的平衡间会允许一定百分比的defect
。而有些妈妈们提到的一些品牌的奶粉不好冲泡开，就是因为在spray drying过程中一
些工艺条件的设定没有使得rehydration ratio达到optimum，这也是平衡质量和效益的
结果。
我个人比较倾向于相信是干燥过程中产生的一些defects，不过如果妈妈们不放心可以
