"Half-water-hydrolysis"method is used to modify the preaminolysis of phenylenediamine in"step coupling polymerization". First, dehydrochlorination polycondensation between Si-OH and Si-Cl group during polycondensation reaction is employed instead of dehydration reaction between Si-OH groups before, which avoids the disconnection of Si-N bond destreyed by isolated water and improves the H-bonding template effect of the bridged-phenylenediamine.

The orders Magnoliale, Laurales, Piperales, Illiciales, and Ranunculales were selected as a complex outgroup. The evolutionary polarity of each character was determined using the outgroup comparison method. On the basis of the character-coding matrix, the phylogenetic trees were constructed with Camin-Sokal method and Farris-Wagner method, implemented in PHYLIP package.

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
