    When the gas of the chemistry-pure polyatomic molecular is in a closed container and is dissociated into photofragments by the irradiation of the light of the special frequency, we can imagine easily that the pressure in the closed container will change. In this paper, from statistical principle, we have carefully deduced the law of the change between pressure and time,which will play a positive role in exploring the interaction law of light and matter.

    We have chosen 3 kinds of red dry chilies as experimental materials and divided them into 3 groups.Through 54 experiments,we have systematically studied the main factors that effect the rate of gains and qualities of chilired. The conclusions are drawn as follows: 1) The rate of gains and qualities of chili red vary greatly by using the same material but different technology.That's to say, there is a close relationship between the production technique and the rate of gains and qualities. Of the six production techniques in producting chilired, Technique  Ⅰ is the most superior,Technique Ⅱ  is the second superior,Technique  Ⅲ is less superior and products are not up to standard by using Techniques Ⅳ, Ⅴand Ⅵ. 2) The rate of gains and qualities of chili red also vary grealy by using the same technique but different chili materials.

    The different result of the different treatment sample of the nutrition contents shows that Similacina atropurpurea has high nutrition value. Its total amino acid is 24.76%, which includes 17 kinds of amino acid except TRP.Its protein content is 41.6% of dry material. It is flourish in mineral elements but is low in sugar content. The loss of the nutrition contents of salted sample is larger. The processed canned sample has been rather affected to remain Vc.

    Seedlings of two rice cultivars, Yushuinuo and Zhefu 802, acquired systemic resistance to Xanthomonas oryzae pv. oryzae( XOO) strain 76- 25 with high virulence when induced by XOO 75- 1 strain with weak virulendce.Activities of superoxide dismutase( SOD) , catalase( CAT) decreased in leaves pre-treated with XOO 75-1, However,lipoxygenase( LOX) activity and malondialdehyde(MDA) content increased after treatment. Tiron( 4, 5-dihydroxy1-1, 3- bezene- disulfonic acid) , which can specially react with O- .2 ,weakened induction effect on the items mentioned above by XOO 75- 1. It was also found that the incompatible interaction type between 75-1 strain and the two cultivars turned into something like compatible interacton. It suggested that membrane lipid peroxidation damage mediated by active oxygens like O- .2 and changes of defense enzyme activities were related to systemic acquired resistance to XOO in rice seedlings.

    From September, 1998 to August, 1999, the Heamotological indices of Southern catfish( Silurus meridionalis ) are investigated. The result shows that the erythrocyte count and hemoglobin content value of Silurus me ridionalis are higher than those of Ari stichthys nobilis, Carassius auratus, Megalobrama amblycephala and Carassius auratus cuvieri , which indicates the consistency with its eating flesh habit and the features of fast growth and less disease. The differential leukocyte count is a new type, i. e. , the kind that is composed mainly by lymphocytes, and has few neutrophilic granulocytes and monocytes and many thrombocytes. The erythrocyte count , the percentage of lymphocytes,the percentage of thrombocytes and the size of all the kinds of blood cells have significant year-round changes.

    In this paper, we introduce the projection of a matrix into the vector quantization. In the process of searching the best matching code word, some candidate codewords are first discarded in the dimensionaligy reduced space. The inequality between the MSE distance and the mean value or the variance of the candidate codeword is used in the elimination process.The experiment shows 98% of the candidate codewords is discarded, only about 2% of the candidate code words has to compute the MSE distance.

Compared with 32 training companions having the same fraining companions having the same fraining , these canoeists had higher SCL- 90 scores,more posi tive items , and sho wed more anxiety , fear and depression( p < 0. 05~ 0. 01) . In addi tion, CD2, CD4, CD4/CD8 in their T lymph cell sub-groups were lower ( p< 0.05~ 0.01) and CD8 were higher( p< 0. 01) . The low immunity may result from socipsychological factors in fraining.
