Work as C<When 0, then representing f3 is flex point retaining, and further determines that the corresponding crest value of flex point f3, by f1, f2, f3,
F4, f5 and f6 delete, and after continuing to extract deletion, flex point judges front 6 spectrophotometric spectra data of collection as computation interval, until
Till the quantity of computation interval afterwards is less than 6;
Work as C>When=0, f1 will be deleted, and extract f7 and form a new computation interval, now f2, f3, f4, f5 and f6 are corresponding
Position before move so that f2, f3, f4, f5, f6 and f7 become new f1, f2, f3, f4, f5 and f6, until new computation interval
Quantity be less than 6 till;
Using each computation interval above-mentioned determine flex point as meet condition spectral reflectivity (as f3, f9, f15,
F22, f28 etc.), and further determine that spectral reflectivity meets corresponding spectrophotometric spectra data during condition, and corresponding ripple
Peak value.
