采用AFLP分子标记方法对云南中甸的6个黄花杓兰居进行了遗传多样性水平、遗传结构及克隆多样性研究,其中两个居用样方取样法分析其克隆空间结构。

Based on plentiful isotopic dating data and geological studies, the authors, in this paper, discuss the geological meanings of the two isotopic ages given by Lapierre et al., and conclude:① Mesozoic volcanic activities in Zhejiang are most frequent in 130~83 Ma, that is, from the early to late Cretaceous but not the late Jurassic;② The Jiande and Moshishan groups are nearly in the same period and not in an upper—lower stratigraphic relationship with each other;③ The period of 110~100 Ma is a transitional stage from the early high-K calc-alkaline dacite—rhyolite associated with diorite—granodiorite) to the late basalt—rhyolite(associated with K-feldspar granite—alkali granite).

本文就Lapierre等文中124 Ma和97 Ma两个年龄的地质意义、幕次划分以及浙西与浙东火山岩时代对比作出评论,并厘定浙江中生代火山岩时代归属,提出:①浙江中生代火山活动时代为132~83 Ma;②浙西建德与浙东磨石山火山岩并不存在上下关系,地质接触关系、古生物组合和大量同位素定年数据都不支持Lapierre等的浙西与浙东火山活动幕次的对比方案;③ 110~100 Ma为早期高钾钙碱性英安岩—流纹岩(伴生闪长岩—花岗闪长岩)向晚期玄武岩—流纹岩(伴生钾长花岗岩—碱性花岗岩)过渡的转折期。

但是纵观目前的研究现状,笔者认为仍有一些局限与不足,大部分文献都是在经验研究和实证研究基础上对FDI集的归纳和总结,缺乏解释FDI集的系统性理论框架。

So promis'd hee, and Uriel to his charge Returnd on that bright beam, whose point now rais'd [ 590 ] Bore him slope downward to the Sun now fall'n Beneath th' Azores; whither the prime Orb, Incredible how swift, had thither rowl'd Diurnal, or this less volubil Earth By shorter flight to th' East, had left him there [ 595 ] Arraying with reflected Purple and Gold The Clouds that on his Western Throne attend: Now came still Eevning on, and Twilight gray Had in her sober Liverie all things clad; Silence accompanied, for Beast and Bird, [ 600 ] They to thir grassie Couch, these to thir Nests Were slunk, all but the wakeful Nightingale; She all night long her amorous descant sung; Silence was pleas'd: now glow'd the Firmament With living Saphirs: Hesperus that led [ 605 ] The starrie Host, rode brightest, till the Moon Rising in clouded Majestie, at length Apparent Queen unvaild her peerless light, And o're the dark her Silver Mantle threw.

他应允了;尤烈儿便乘光线回到自己的岗位,那光线已经把尖端转而向上,冲入苍穹,尤烈儿被斜带而下,到沉入亚速尔岛下面的太阳那儿去。不知是那颗主星以难以置信的速度每天向那儿滚转,还是较迟钝的大地另有到东方的捷径,他被留在那里,在西方宝座上伺候的云彩,被回光饰成紫金辉煌。这时夜幕悄悄降临,苍茫的夜色把万物包进深灰色的衣裳里。寂静伴随而来,兽已归窝,百鸟已归巢,一切都已入睡,只有夜莺清醒着;她彻夜歌咏韵味无穷的恋歌。"寂静"异常欣喜。那时苍穹放出碧玉般鲜艳的萤光。领导各星的金星,最为明亮,直到月儿在云彩簇拥的庄严中升起,终于脱去面纱,展现女王的丰姿,放出无比的光辉,在"黑暗"上面,披上她那银色的宽袍。

Firstly, according to the difficulties in the optimization of chemical engineering and the intrinsic disadvantage of deterministic optimization algorithms, this work analyzed the importance and advantage of stochastic algorithms, and proposed some important aspects in research on them. Secondly, genetic algorithm was applied to two problems of data driven modeling, one of which was combination problem, the other was mixed integer nonlinear programming. Thirdly, systemic investigations were made on the basic structure, dynamic behavior and modifications of particle swarm optimization. Lastly, two kinds of proposed PSO algorithms were applied on calculation of phase equilibrium, which is nonconvex optimization.

本文首先根据化工优化中存在的困难和确定性优化算法内在的缺点,分析了随机优化算法的重要性,并提出研究随机优化算法应注意的问题;其次,将遗传算法应用于两个数据驱动建模问题,一为组合优化问题,一为混合整数优化问题;再次,从粒子优化算法的基本结构、运动行为、改进方法做了系统的研究:最后,将提出的两种改进粒子优化算法应用于相平衡计算问题,为非凸全局优化问题。
