The result showed that the polarization of populations and gene fluxes are different in different species. The polarization and gene fluxes of populations of 3 Nitavias are lower except N. sphaerocarpa. The heredity coherence of each population is change from 0.8561 to 0.9694. The polarization in the populations is low, and they have the together ancestor. This is similar to morphology and cytology result, so RAPD is a useful supple mentary method in assessing genetic relationship among Nitraria species.
结果表明:白刺属植物的遗传分化程度和基因流因种而异,除球果白刺以外,其余3种白刺的种群间有很大的基因流,其遗传一致度在0.8561~0.9694之间,而种间遗传分化程度较低,故4种白刺有着相近的祖先,这与形态学和细胞学的分析结果一致,说明RAPD分析方法可从分子生物学角度为白刺属植物的系统学分类提供更为有利和可靠的证据。

As an aesthetic category, game is, no doubt, very important in its relations with many basic questions. So far as its many manifestations as shown in different theoretical systems are concerned, game, as a category, is vague in form; it is often used as a tool to explain theories and it is characterized by its metaphoricalness when elaborating.
作为美学范畴,就其与美学研究中的许多重要问题的关系来看,它无疑是十分重要的;可就其自身在不同理论话语体系中所呈现的迥然各异的表现形态而言,&游戏&范畴具有形态上的模糊性,说明理论问题的工具性,以及阐述问题时具有的隐喻性的特点。

Especially when July ,1936 called Japan And Manchoukuo Peace Treaty's Postscipt,add the posipolity of "dual nationaliy.To Koreans residing in Northest China, they also had dual nationality because of some history things and China Nationality Law which was revised in 1929.1f deal with this thorny thing failurely, the Janpan goventment would carried that the people think the " Manchoukuo only was puppet country.
居住在东北的日本人均可拥有&满洲国&的国籍,但是日本人在感情上并没有脱离日本国籍而加入&满洲国&国籍之意,这就增加了日本人双重国籍的产生;尤其是1936年7月所谓的《日满条约》和其附属说明中更是表明了日本人是以不脱离本国国籍为前提的,其结果更是增加了在满日本人双重国籍情况的产生。

Focal ischemia induced by photochemically thrombotic distal middle cerebral artery occlusion model to adult rats results in necrosis at the infarct core and activation of complex signal pathways for cell death and cell survival in the penumbra. The effects of ghrelin on regional cerebral blood flow in penumbra areas used by a laser Doppler Flowmeter.
本实验室前期工作初步证明ghrelin可保护谷氨酸及脂多糖诱导的原代培养大鼠脑皮质神经元的损伤,也能减少线栓大脑中动脉引起的脑梗塞体积,说明ghrelin对脑缺血引起的神经元损伤具有一定的神经保护作用,有可能成为一个内源性神经保护多肽,具有重要的理论价值和实践意义,值得深入研究。

The somatic hybrids usually showed specific bands and combined all the bands of both parents. In combinations, some new bands were detected, and occasionally specific bands of parents were lost, which indicated that chromosome recombination and exchange happened after fusion. Additionally, in some combinations, specific bands from leaf parent were detected, which revealed the plants were of putative hybrid origin, because leaf protoplast cannot redifferentiate by both single culture and co-culture.
体细胞杂种一般表现为具有双亲的特征带,且综合双亲的所有带,但在部分杂种中检测到了双亲都没有的新带,也发现有丢失亲本的特征带或共有带的现象,说明融合后染色体发生了重组和交换;有的引物只检测到叶肉亲本的特征带,根据柑橘叶肉细胞无论单独培养还是共培养均不能再生的事实,可推测其为体细胞杂种或二倍体叶肉亲本型胞质杂种。

6The studies on SSR identification of P. shenzhou show that: The leaf, bud, bast and xylem of type A plant had no components of type C, showing that the above-ground of type A was already pure. Type A plant had two kinds of color roots, the rufous roots belonged to type A tissue, the yellow roots belonged to type C tissue through the SSR identification.
6由深州杨SSR鉴定研究可得:深州杨A型植株的叶、芽、韧皮部、木质部已经检测不到深州杨C型的成分,说明深州杨A型的地上部分已经纯合:深州杨A型植株的地下部分含有红褐色和土黄色两种根,经检测,红褐色根是属于深州杨A型的纯合组织,土黄色根是属于深州杨C型的纯合组织。

Based on these results, it was concluded that in conditions where eye movements are needed, besides saccadic suppression, the higher central system must calculate and control the eye movements, which affects its capacity to process the text information.
通过固定窗口显示方式和知动窗口显示方式条件下中文阅读的比较,排除了强迫阅读的因素,说明有无眼动是产生阅读速度差异的主要原因;根据以上实验结果,可得出结论,在有眼动的情况下,除了saccade抑制影响阅读和识别外,主要的因素在于高级中枢对位置信号的处理,眼动的驱动控制及运动过程影响了高级中枢对阅读内容和识别内容的解码速率。

本论文在对这两种方法进行认真的分析后,说明它们对不连续面的描述并不合理,也无法反映出不连续面的主要力学特性,同时指出,将带有不连续面的岩土工程问题作为接触问题计算更为合理,它可将不连续面受力变形的主要特点反映出来,即:(1)接触面具有相应的&抗剪强度&,即当接触面上某一点处的切向应力小于该点处的抵抗强度时,点对共同变形;达到强度时,则沿切向发生相对滑动;(2)在整个变形过程中,发生接触的变形体不能相互侵入。

Eclogites north of the fault give similar Sm–Nd isochron ages (131–126 Ma) but otherwise differ in that they are strongly overprinted by a lower pressure assemblage and, along with associated HP/LT rocks, give much younger 40Ar/39Ar ages of 88–55 Ma indicating a later amphibolite facies metamorphic event.
