Method of fuzzy mathematics and the concept of pollution intensity are applied for evaluating and demarcating water bodies with regard to pollutants, e.

They do not aim at cutting pollution,but can alter pollution intensity and pollutant emission through altering pollution production in producing process.

Study on Color Intensity of Direct Light Turquoise Blue GB by UV Spectrophotometry;

5%, the mean infection intensity was 16.

To study microcosmic infection of computer viruses,based on reseaching infectious mechanism of viruses and operating system characteristics,establishes and analyses the model of computer viruses random infection,which concludes that the number of virus infection increase linearly with steady infection intensity on single-process operating.

100 wild Macaca mulattas samples were collected from Mianyang area to monitor the infection rate and the infection intensity of intestinal parasites by saturate saline flotation and eggs precipitate collection method respectively.

Changes with seasons in breadth and overlapping of niche of the three kinds of parasite, Acanthocephala, Digenea and Capillaria in the digestive tube of Monopterus albus, and its relation ship with the intensity of infection correlation were investigated.

It is discovered that the species of helminthes parasitizing in the finless eels are much the same, but the rate and the intensity of infection of the parasitized host are quite different.
