Theoretically, its calculation complexity is studied, while it is tested empirically by learning multi-samples generated randomly. The comparative analysis and applications show it has some merits of rapid searching and good clustering effect. B3. An immune network optimization algorithm with information feedback, which can solve special complex function optimization problems with high dimensions which objective functions are formed by summing multi-subobjective ones, is constructed based on the clone selection principle and the immune network regulation of the idiotype immune network.

为了对免疫系统中抗体如何学习抗原特征的整体行为有一定的认识，从单个抗体识别抗原及多个抗体并行识别抗原的特征出发，利用免疫应答的相关原理及免疫细胞的免疫功能设计了适合于批量样本聚类的抗原特征学习算法，理论上分析了其计算复杂度，获得了此算法中的关键参数与其搜索性能的关系；应用上，该算法通过对实际的多样本学习，获得了搜索速度快及聚类效果好的优点，比较分析表明这种方法是可行的和有效的。

Objective: The first aim of this study was to investigate bcr-abl associated T cell receptorVαand Vβgene repertoire by analyzing the restricted usage and clonal expansion of TCRVαand Vβsubfamily T cells from the normal individual peripheral blood induced bybcr-abl peptideso The second aim was to construct the idiotype TCR Vα-PIRES-TCR Vβeukaryotic vector and investigate its expression in vitro. The data will be expected toprovided the methods in development of the leukemia antigen specific cytotoxic Tlymphocyte modified by the specific TCR.

The results indicate that polyborazine precursor prepared at 150℃ for 10 h and propylamine/isopropylamine molar ratio 2:1, could possess nearly linear molecule skeleton and he prone to melt spinnability. When melt at 90℃, the precursor fibers are prepared with average diameter 10-20μm and BC1.27 N1.52 H structure. After curing process and sintered in NH3 at 1200℃, the near-stoichiometric BN fibers was obtained, which proved this precursor is apt for preparation of BN fibers.
