At first, we made up an appropriate configuration of design and determined which factors might have effect on slim products. Then we determined control factors and standards of control factors that were set according to the standard of Dr. Taguchi's experimental orthogonal array. With the bigger the better of orthogonal array, L9(3^4), we conducted confirmation procedure on operating factors by use of cypress essential oil on slim cosmetics. The experiment was used to obtain best combination of parameters by S/N ratio and characterizations that were based on the data constructed by Taguchi Methods.

Moreover, as the heat flux approach to CHF, numerous vapor mushrooms periodically extruded from the perimeter of fin array are observed. This mechanism will cause the dry-out situation in the central part of fin array. The closer fin spacing and longer fin length can provide larger heat transfer. However, the results also demonstrate that early decay on overall heat transfer coefficient as the fin spacing is closer or fin length is longer.

此外，间距0.5mm且高度4mm的鳍片阵列，其热传系数并不随热通量的升高而增加，在中高热通量区，其热传系数保持在一固定值，而其它低深宽比的鳍片阵列，热传系数则是随著热通量升高而增加，到了高热通量区，热传系数会有一最大值，之后会随热通量增加而递减。
