Comparison of diaspore shape,size,and mass of main desert plants in the lower reaches of Tarim River of Xinjiang,China.

Their size,physiological and fermentation properties were determined and studied,and their small-volume fermentation tests in laboratory have been done.

(2) The optimal number of reserves has little relationship with initial size of .

By using the views and methods of cognitivism,this article analyses the appearance orders of seven spatial dimensionality words,their frequency and the mapping domains of metaphor of the "big/small" in the compositions over 1.

A mutant plant Yuan 3 was screened in the Impatiens balsamin,a plants grown from the seeds treated by space flight, and the chromosome numbers and size of microspores in the descendant plants from SP_1 To SP_3 generation were tracked.

In this study,the least square method for separating twofold broadening effect of crystallite-fault were proposed and used to characterize the average crystallite size and stacki.

The result shows that its crystallite size is decreased,micro\|strain and effective temperature are increased as well as its crystalline lattice is disordered with grinding time increasing.

And the calculation of crystallite size derived from Debye-Scherrer s equation is carried out in terms of Least Square Method by self-written VB program.
