As can be seen from Figure 4, 2 and 4 of their degree of polymerization of good, but overlapping serious; three samples with 2 and 4 of differentiation between the good, but with some i-level samples are cross; At the same time, some a sample with two and four samples confused. This sort of tea is rated as superfine pre-Clear & Bright West Lake dragon well tea, class E, and it is the authentic.
Multi-class discriminant analysis for feature optimization and establish discriminant model to 1.67 for the critical value where the two selected eight features, and the establishment of discriminant function, the eight characteristics of the order of importance were: xlz, xll, xy, x13, x8, x15, xs, xl.  It is picked right ahead of the Clear and Bright (the fifth solar term), whose cost performance is the highest among all the pre-Clear & Bright West Lake dragon well tea.
