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.

Double helix model significance, not only means that has verified the DNA member structure, it also has prompted more importantly the DNA duplication mechanism: As a result of the gland fat ling always with the thymine pair, the bird fat ling always with the cytosine pair, this explained that two chain's basic group orders are each other supplementary, so long as had determined a chain's basic group order, another chain's basic group order also determined.

双螺旋模型的意义，不仅意味着探明了DNA分子的结构，更重要的是它还提示了DNA的复制机制：由于腺膘呤总是与胸腺嘧啶配对、鸟膘呤总是与胞嘧啶配对，这说明两条链的碱基顺序是彼此互补的，只要确定了其中一条链的碱基顺序，另一条链的碱基顺序也就确定了。
