查询词典 yolk nucleus

Endo G is a mitochondrial DNA enzyme which translocates to nucleus after releasing from mitochondrion and cuts chromatin DNA into nucleosome fragments in a caspase-independent manner.

Endo G是一种线粒体DNA酶，当其从线粒体释放出来之后，可以转位到细胞核，并且以caspase非依赖性方式将染色质DNA剪切为核小体碎片。

The efferent projections of hypothalamic and brain stem nucleuses to nucleus dorsalis nervi vagi were studied by means of the retrograde axonal transport of HRP technique in cats.

本文用HRP轴突逆行输送法，对猫下丘脑和脑干一些核向迷走神经背核的传出投射进行了研究。将HRP注射至迷走神经背核后，较多的标记细胞见于同侧下丘脑的室旁核、背内侧核以及中脑的中央灰质和被盖腹内侧区。

The injured gill cells had a different ultrastructure, with endoplasmic reticulum dilated and vesiculated, mitochondrial cristaes partially disintegrated, gill fibre cuticles denatured and dropped. The ultrastructural damages to hepatopancreatic cells were characterized by the decrease of microvilli, swelling and breaking up of mitochondria, expansion of endoplasmic reticulum, disruption and vacuolization of nucleus, tumefaction of nuclear membrane and increase of lipid droplets. As for the toxicological changes of myocardial cells, the mitochondria were swelling, having a lot of vacuolus and disintegrating, while the myofibrils were irregular with endoplasmic reticulum dissolved.

鳃细胞的损害表现为鳃丝水肿，细胞器溶解，角质层变薄，线粒体、内质网的肿胀、解体；肝胰脏细胞的主要损害特征为肝管微绒毛减少，线粒体水肿解体，内质网扩张，细胞核空泡化，核膜水肿和脂肪滴增加；心脏细胞的毒理变化为线粒体内嵴肿胀、瓦解，肌原纤维不规则，内质网溶解。

The result shew, Chromatin broke into pieces which dispersed around the irregular nucleus, nuclear outer member disintegrated; Mitochondria condensed, cristae of which disintegrated partly; The endoplasmic reticulum dilated, vesiculated, gradually disintegrated; A great number of dense granules appeared in the cell. To sum up: Enrichment of heavy metals in Eriocheir sinensis, Macrobrachium nipponease, Cipangopaludina cathayensis is obviou""

综上所述：我们首次证明上海地区沼虾、河蟹、园田螺对重金属元素富集能力要明显强于淡水鱼类；肝、鳃是鱼、虾、蟹体内重金属富集的主要部位；Hg和Cr为高富集元素，Cd是中富集元素，Cu和Pb为低富集元素；罗氏沼虾对镉离子和锌离子的96小时的半致死浓度（LC50）分别为0.115mg/L和0.68mg/L；首次证明锌离子、GSH在一定范围内可以抵抗镉离子对罗氏沼虾肝胰脏破坏。

原子是由原子核和它周围的电子组成的。

The nucleus of an atom is the small core of protons and neutrons.

原子的核是由质子和中子组成的小核心。

With positively charged protons and neutrons without charge of the nucleus.

带正电荷的质子和不带电荷的中子组成原子核。

Atoms are made from a nucleus of protons and neutrons and a cloud of electrons.

原子是由质子和中子组成的原子核与围绕原子核的电子云构成的。

The grain filling of superior spikelets was a continuous progressing process without interruption: Free nucleus→endosperm cell formation→endosperm cells differentiating into aleurone layer and starchy endosperm→composition and storage of reserve materials such as starch and storage proteins.

水稻强势籽粒的胚乳发育是一个无间断的连续过程，经过游离核期→胚乳细胞化→胚乳细胞分化发育成糊粉层和淀粉质胚乳→合成和累积淀粉、蛋白质等贮藏物质，约在20d以内完成胚乳发育的全过程，不同强势籽粒的胚乳发育进程大体一致。

You can snipe the second and third union leaders from this position.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
