By linear regression analysis, and basing onexperimental data of crystal growth kinetics, experiential equations of minimumparticle size, maximum particle size, number of daughters produced in one breakageprocess, width of metastable zone of breakage process, breakage rate kernel anddaughter distribution were obtained.
Twelve climatic factors affecting wheat productive tillering rate, kernel number per spike, thousand-grain weight at 8 typical sits were caculated and analysed by fuzzy clustering method. Henan province was divided into four parts when λ= 0. 857,they were south of Yu (Yu is short name for Henan), north of Yu, middlenorth of Yu and middlesouth of Yu.
Data of seed germinative traits between five supersweet (sh2)corn lines and four normal corn lines were collected following a NCⅡ design. Genetic analysis for germinative traits such as germinative viability,germinative rate,kernel weight and activity of ɑamylase in supersweet corn was conducted with genetic model for triploid endosperm.
Nut width,per nut mass,nut shell thickness,kernel rate,kernel total fat content and kernel total protein content of 803 Chinese walnut(Juglans regia L.) varieties were investigated in this paper. The six economic characteristic values for new grading criteria were given for amending the two national quality criteria.
We also investigate another simple model with the asymmetrical rate kernel (), which exhibits some scaling properties quite different from the symmetrical one.
We propose a simple model with the symmetrical migration rate kernel at which the monomers migrate from the aggregates of size k to those of size j.
A kinetic model of the growth of aggregates driven both by reversible migration and by irreversible aggregation is proposed. Assumed that the aggregation rate kernel is while the migration rate kernel is or . Based on the Smoluchowski rate equation, we obtain the analytical solution of the aggregate size distribution. The results show that the aggregate size distribution approaches a conventional scaling form.
