时延细胞神经网络（DCNN）的全局稳定性

讨论具了延的细胞神经网络（ＤＣＮＮ）的全局渐近稳定性，利用Ｌｙａｐｕｎｏｖ泛涵方法，通过构造Ｌｙａｐｕｎｏｖ泛涵，对ＤＣＮＮ的稳定性进行再分析，给出了ＳＣＮＮ全局渐近稳定时一些充分条件。     

日本福井沿海人工育成红鳍东方鲀Takifugu rubripes 感染 Heterobothium sp. 寄生虫病所需时间以及相关问题的研究

为了研究室内人工育成的红鳍东方鱼屯Ｔａｋｉｆｕｇｕｒｕｂｒｉｐｅｓ移到海区后需要多少时间会感染上ＨｅｔｅｒｏｂｏｔｈｉｕｍｓｐＧ寄生虫病，本文作者于１９９８年１月７日至３月１７日在日本福井沿海进行了网箱养殖试验。结果表明，在海区放养后１个月到２个月之间，鱼不同程度地被Ｈｅｔｅｒｏｂｏｔｈｉｕｍｓｐ所寄生。在本试验中，作者在观察红鳍东方鱼屯寄生虫发病期的同期，还对其在试验过程中的外部和内部症状、身体有关部位有无细菌感染、血液Ｈｔ值与血液成份以及生长情况等相关问题进行了研究。     

Factors influencing the outcome of embryo freezing and Ihawing program

Objective: To investigate the factors that might influence the sucess of an ernbryo freezing and thawing program.Method: The relationship between the pregnancy rate in 73 cycles of embryo freezing and thewing program and the following factors was analyzed;matermal age,E2 level at the time of HCG trigger,embryo storage time,number of thawed embryos transferred,presence of sponsoring embryos and intact embryos.And the suvival rate of thawed embryos with different morphology,cell stage and storage time was evaluated.Result:Transfer with three of more than three thawed embryos resulted in pragnancy rates of 38.5% and 35.7%,respectively.compared with 5.3% for transfer of fewer than three embryos.The presence of sponsoring embryos and intact embryos significantly incresses pregnancy rate in embryo freezing and thawing program .No other factor examined had any effect on pregnancy outcome.The survival rate of good morphology embryos was higher than poor ones,but was not influenced by cell stage and storage time.Conclusion:Embryo morphology before freezing , number of thawed embryos transferred and the presence of intact embryos are important to the outcome of embryo freezing and thawing program.     

一种连通孔最小化的布线算法

提出了一种先分层、后布线的减少连通孔的布线算法，该算法的主要思想是从总体上考虑布线的，即先从总体上考虑连通孔最小化，再行布线比传统的布线方法更为紧凑和有效，最后通过实例验证了该算法，并给出了计算结果
