The quality of commercial Mei-Gin products are different from each other XVI and shows unsatisfied results. however, In future, possibly, HMF can be applied as a bioactive standard marker for quality control of Mei-Gin. Based on the qualitative and quantitative analysis of HMF, we can establish the model of quality control, and find out facilitative, efficient, and representative chemical fingerprint for commercial Mei-Gin products. Standardizng the Mei-Gin product from the same procedure will bestead the market of plum in Taiwan. Not only advancing the economic value of plum, but also accelerating the competitiveness in marketplace. Establishent of quality control model with HMF as a bioactive standard marker will be crucial issue in the future.

目前在台湾，梅产品还没有一个可以判断品质优的标准，市面上的产品品质也是差齐，在品质管制方面一直无法获得人满意的成果，透过HMF 的定性定分析，可确初步品质管制的模式，为梅产品订出一个简有效且具代表性的化学指纹图，使所有同一产程的产品一致化以及标准化，这将对於梅子产业有相当大的助，仅可以提升梅子的经济价值，并且增加在市场上的竞争，因此用HMF 作为Bioactive standard marker，并且为梅产品建起品质管制模式在未将会是相当重要的研究之一。

Secondly the author proposes the decision theorem of convex function which provides a judgment basis of whether a function is a convex function. Thirdly the author summarizes and proves the convex function's operational ,basic , differential and integral property. Finally the author proves several famous convex function inequalities, such as Jensen inequality, Holder inequality, Cauchy inequality and Minkowski inequality. The author also provides the application of these inequalities and illustrates the importance of convex function's basic inequality and integral property in the proving process.

Furthmore the second criterion of weak controllability, accessibility and strong accessibility, which is more standard, more succinct and more practical, is obtained. On the basis of the first criterion and the second criterion, several important problems about nonlinear controllability are discussed, which include 1 local controllability; 2 three classes of local controllable decomposition, separately by means of local coordinate changes in the neighborhood of a nonsingular point, a point on a singular surface or a designated point x〓 with a designated input u〓; 3 the character of controllability of the ith state variable x〓 in different controllable areas and their boundaries.
