The principle of triadness applied in a language, in a genetic code and other codes is used, i.e. the logic homology is employed. The purpose are （1） to show the use of a systematic approach to the analysis of elements of crop capacity structure of winter wheat; （2） to analyze efficiency, the years of harvests and winter hardiness; （3） to find the way of selection and varieties assessment in terms of the elements efficiency. The quantitative compatibility as the highest with the sign ＂＋＂ and the lowest with the sign ＂-＂ in terms of elements efficiency gives eight types of crop capacities. The type of crop capacity structure ＂＋＋＋＂ can serve as a full （higher） measure of a variety adaptableness and optimality of technologies. The triad of three characteristics as a type-＂＋＋＋＂ in which the first sign is the quantity of ears （QE）; the second is a quantity of grains （QG）; the third is the weight of grains （WG） creates the highest level of crop capacity.展开更多

Meanwhile, the effect of Gardenia extract ZG on the adsorption quantity on the surface of Hep-2 cells was determined by flow cytometry. It was demonstrated that adsorption of HSV-1 on the surface of Hep-2 cells exhibited the character of saturation and specificity and heparin sodium could prevent attachment of viruses on these ceils. These results are in accord with those reported previously. It was also proved that the manner of drug-use prior to adsorption or simultaneous use of drug and adsorption was better than adsorption prior to drug-use, and the inhibition rates of the former and latter manner were 84.76% and 82.92% respectively. Three manners of drug-use with Gardenia extract ZG were all effective to reduce the adsorption quantity of viruses, especially the manner of simultaneous use of drug and adsorption with an adsorption inhibition rate of 68.46%. From the above observation, it is apparent that the mechanism of anti-viral activity of Gardenia extract ZG may be via several steps involved in the HSV-1 adsorption.展开更多
