Nigra, B. oleracea and B. carinata belonged to class 2A according to the classification of karyotypes by Stebbins (1971). According to Levitzky's and Stebbin's view, the more asymmetric karyotype a species has, the more evolved it is. Therefore, B. campestris is the furthest evolved species among the elementary species, and B. juncea and B. napus the furthest among the amphidiploid species. Compared with the previous reports, there is no any cytoplasm in the chromosome sample prepared using this protocol which is very useful for the karyotype analysis, as well as the FISH research on Brassica species.
对上述研究结果分析表明:(1)芸薹属复合种是由基本种相互杂交而成;(2)B基因组与A或与C基因组亲缘关系较远,而A和C基因组亲缘关系较近;(3)芸薹属复合种在演化过程中,发生了染色体结构上的重排现象;(4)芸薹属复合种演化过程中,rRNA基因位点发生了减少;所获结果与国外同类报道相比表明:国内的白菜型油菜存在新的rRNA基因位点,即rRNA基因在芸薹属同一物种不同的品种间具有多态性;有关这类研究国内尚未见报道。

Glyphosate brought the biggest vice-effects, clethodim took the second and fenoxaprop-p-ethyake minimum:(1)As to the pure growth, MDA accumulation, the relative permeability of plasma membrane and chlorophyll content, glyphosate had evident influences on them in the daily dosage, 1/2 and 1/4 of the daily dosage . The walnut seedling dried and died twenty days later.(2)The influences of clethodim in different concentration such as double daily dosage, daily dosage and 1/2 of daily dosage on the above four indexes demonstrated differently, the more concentration was, the more severe the influence. was. With the concentration reducing, the influence weakened gradually.(3) Double daily dosage, daily dosage and 1/2 daily dosage of fenoxaprop-p-ethy exerted a slight vice-influence to the MDA accumulation, the relative permeability of plasma membrane and chlorophyll content.
1用草甘膦常用量、1/2倍常用量、1/4倍常用量处理之后,对核桃苗新梢生长量、叶片中丙二醛含量、膜相对透性以及叶片中叶绿素含量的影响最大,几乎所有样枝的新梢在药后20天后都发生干枯及死亡现象;(2)用收乐通2倍常用量、常用量、1/2倍常用量处理之后,对核桃苗的新梢生长量、叶片中丙二醛含量、膜相对透性及叶片中叶绿素含量的影响,呈现出浓度不同影响亦不同的现象,浓度越大,影响越明显,随着浓度的降低,影响也逐渐减弱;(3)用威霸2倍常用量、常用量、1/2倍常用量处理之后,对核桃苗新梢生长量、叶片中丙二醛含量、膜相对透性及叶片中叶绿素含量的影响最小;(4)三种除草剂对核桃苗的影响随着药后时间的延长,其影响在逐渐减小。

5As for creep of the marine soft soil, the micro-mechanism of one-dimension creep is proposed: Under slight load, the initial bone strength and rank will be destroyed, while, as the time advances, deformation increases, void ratio decreases and inner particles move, bonding among particles become tight and the structure changes, and then the restitute of the old structural damage exceeds the new one. Consequently, creep will trend towards decelerate steady state ultimately.
揭示了软土一维蠕变的微观机理:当土样受荷较小时,尽管土样初始结构要受到影响,某些颗粒连结强度、胶结性、定向排列性遭到破坏,但随着时间的增长,变形增大,孔隙比减小,土体内部颗粒发生位移,使得某些颗粒结构间的联结更紧,胶结因而逐渐恢复,定向排列性亦略有回升,从而使得结构缺陷的愈合超过胶结的破坏和新缺陷的形成,蠕变最后趋于减速稳定状态。

Traditional ways of demarcation tends to focus on revelation of the characteristics of essential facilities that have proved far from satisfactory,among which,the criterion laid down by the court in the case of MCI seems tautological in logic;the public welfare criterion appears to transfer a vague issue into an even indefinite one;while the competitor standard ignores the integral effectiveness of the whole market;...
其中,美国"MCI"案中法院提出的标准存在逻辑上的同语反复;公共利益标准将有待澄清的问题转化为了另一个不确定的问题;竞争者标准忽略了市场的整体效果;消费者偏好标准只是对于特定情况的处理,不能成为一个基本的判断标准。核心设施界定的关键是对"不可复制性"的理解,通过借鉴相关市场界定的方法,可以确定替代发生的范围,以及替代实现的程度,从而对正确地适用核心设施理论提供新的思路。

The data show the following ages: 1894±17 Ma and 1847±59 Ma for garnet pyroxenite of the Tiantangshan Group complex, indicating a Paleoproterozoic age; 1462±28 Ma for the metabasic volcanic rocks of the Yunkai Group complex, indicating the presence of fragments of the Meso- and Neoproterozoic oceanic crust in the Yunkai area; 906±24 Ma for the granitic gneiss intrusion is, which should be the product of the global Grenville collisional orogeny occurring around 1000 Ma BP. In addition, an inherited detrital zircon age of 2702±13 Ma was also obtained, which is the oldest age in the Yunkai area and even in Cathaysia, proving the presence of Neoarchean continental crustal material in Cathaysia.
