2.The studies of metallothionein(MT) in invertebrates including mollusca MT, echinoderm MT, annelida MT and arthropod MT(crustacea and insecta) are introduced in this review. The similarities and differences for invertebrate MT and mammalian MT are also analyzed. We suggest that the evolution of animal metallothionein may be a pattern of convergent evolution.
综述了近几十年来有关无脊椎动物金属硫蛋白 (MT)的研究 ,包括软体动物MT、棘皮动物MT、环节动物MT、节肢动物MT(甲壳纲和昆虫纲 ) ,分析了无脊椎动物MT与哺乳动物MT的异同 ,在此基础上 ,提出以下观点 :即从无脊椎动物MT到哺乳动物MT的进化来看 ,动物MT的进化可能是一种趋同进化的模式。收藏指正
3.But the recent discovery of detailed similarities in the skeletal structure of the flippers in all three groups undermines the attempt to explain away superficial resemblance as due to convergent evolution—the independent development of similarities between unrelated groups in response to similar environmental pressures.
但是,最近的发现,这三种动物的鳍足的骨骼结构都有详细的类似之处,这个发现削弱了下文的企图,即把表面上的类似解释为趋同进化的结果——是指类似结构的独立发展,在不相关的种群之间,对于类似的环境压力的反应。收藏指正
4.A New Genetic Algorithm with Adaptive Population Size (NGAAPS) is proposed to overcome premature convergence and slow convergent speed in the later evolution process of simple genetic algorithm.

5.In this paper, how to implement the divergent/convergent design process using the co-evolution of DM and DSM is investigated, including the divergent functional requirements solving based on DM and the convergent solution evaluation based on DSM.
讨论了如何通过公理化设计矩阵与设计结构矩阵的同步演化来实现产品创新设计中的发散与收敛思维,即通过公理化设计矩阵进行功能需求的发散性求解,基于设计结构矩阵进行收敛行评价。收藏指正
6.In the proposed algorithm, the descending search theory of optimization principles is applied, so the iterative effect, only relying on quantum gate, of QEA is improved to speed up the convergent speed, and the possibility of individual retrogression in the evolution process is reduced.
该算法将下降搜索理论应用到量子进化算法中,改进了量子进化算法仅靠量子门进行迭代的作用,从而加快了收敛速度,并降低了个体在进化时产生退化的可能性.收藏指正

8.lt is proved by numerical experimentation that,fbr large scaling multi-apex and no smooth mixed integer nonlinear programming (MINLP),the genetic method can achieve a global solution and is superior to evolution algorithms in feasibility,stabilization and convergent speed of the solution.
数值实验表明:该算法对大范围、多峰、非光滑混合整数非线性规划问题(MINLP)有着较好的全局求解能力,在解的质量、稳定性和收敛速度等方面优于一般的演化算法。收藏指正
