查询词典 dense subset

We proved that there exists a dense G (subscript δ) subset of the complete metric space consisting of the vector optimization problems satisfying some conditions ,and each problem in the dense G (subscript δ) subset has stable solution set, which generalized the corresponding results in the literature.

Followed by the decomposition phase is optimal feature subset selection, in which the optimal feature subset acquired the best divergence is obtained according to interclass/intraclass distance of the training samples. This procedure is implemented by a Genetic Algorithm, with each possible feature subset encoded as chromosome. Fitness scores in GA are calculated and evaluated based on Jeffries-Matusita distance of the selected training samples.

CD8~+ cell is the main T lymphocyte subset in spleen, and B lymphocyte mainly is IgG~+ cell, moreover the amount of these B lymphocytes could exceed CD3~+ T lymphocyte subset after 7 days. CD8~+ cell is the main T lymphocyte subset in tonsil of appendix, and B lymphocyte is IgM~+ cell, and the amount could exceed CD3~+ T lymphocytes after 35 days. After 21 days, B lymphocytes in esophago tonsil are the main IgA~+ cells and the amount exceeds CD3~+ lymphocytes. The amount of CD4~+ lymphocytes is more than CD8+ lymphocytes.4. CD3~+、CD4~+ and CD8~+ T lymphocytes in spleen mainly distribute in periarterial lymphoid sheath. However IgM~+、IgG~+ and IgA~+ cells mainly distribute in ellipsoid periarterial lymphoid sheath and germinal center. T lymphocytes in appendix tonsil mainly distribute in middle and inferior part of mucous and the B lymphocytes mainly in middle and mucous between 4~7 days. Whereafter T, B lymphocytes equably distribute in mucous. CD4~+ cells arrange tightly and mainly occupy the central part in aggregates of T lymphocytes in esophago tonsil and CD8~+ lymphocytes mainly distribute in periphery. Meanwhile B lymphocytes encircle the periphery of aggregates of T lymphocytes. The aggregates of B lymphocytes is mainly the germinal center with lots of IgM~+、IgG~+ and IgA~+ cells. Meanwihle T lymphocytes encircle the periphery of aggregates of B lymphocytes.5. There is an intimate relationship between the development of tissue structure of peripheral immune organs and lymphcytopoiesis. The maturation of tissue structure is stimulated by the immigration of lymphocytes and the mature tissue structure provides place where lymphocytes grow mature and functionate.
