In this paper, we study characterizations of admissible in the general linear model Y, Xβ,ε|ε～(0,σ~2∑. We demonstrate that an admissible linear estimator is as the conditional generalized ridge-type estimation in the no constraint, equality constraint, inequality constraint general linear model. We study the superiority of this conditional generalized ridge-type estimation, and prove that it is superior to the restricted best linear unbiased estimator in terms of mean squares. We also give the choice of the matrix K.

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。
