The result was as follows:The content of chlorophyll,Pn,Fv/Fm and PhiPSⅡ showed wavy changes,whose amplitude of variation was different under variable light intensity.
Through chromosome counting and chloroplast counting cytologically,the proportional relation between different ploidy of the regenerated plants and the range of variation of chloroplasts was revealed,so this method of chloroplast counting in guard cells was practical in squash was proved and the variation of data was offered as a reference for other breeding researchers .
The population dynamics of major pests and natural enemies from the 1st ten-day of March to the 1st ten-day of October in the peach orchards and the variation of numerical characteristics of insect community, such as relative abundance, species richness, community diversity and evenness were systematically studied. The major factors that influence the insect community diversity were analysed.
Next we settle the remaining cases, with a computer-aided variation on the old method of Donkin.

A theorem of Fejér states that if a periodic function F is of bounded variation on the closed interval [0, 2π], then the nth partial sum of its formally differentiated Fourier series divided by n converges to π-1[F(x+0)-F(x-0)] at each point x.
