不对称发育

Their motion asymmetry supported the idea of close correlation between motion perception symmetry and binocularity.

三位双上旋肌麻痹，一位视神经重度发育不全，一位早产儿网膜症，两位合并水平及垂直斜视，一位角膜彼得氏异常和一位网膜先天缺损，他们自出生起就没有发育双眼视觉的机会，他们不对称的运动觉支持了运动觉对称性和双眼视觉之间相关性的理论。

This paper briefly describes the progress in cytoplasm reorganization, dynamics of wall callose, starch granules and organelles in pollen grains, the tapetum development, specific genes, asymmetric division and cell fate determination in developing pollens. Some problems and future research directions are pointed out in this review.

本文针对花粉发育过程中的细胞质改组；胼胝质壁、淀粉粒和细胞器的动态变化；绒毡层的发育；花粉发育特异基因；以及不对称分裂和细胞命运等几个生物学问题的研究进展作了简要综述，最后还提出了一些研究展望。

The homeostatic mechanism controlling the choice between self-renewal and differentiation of stem cells is poorly understood.

但是决定发育过程中干细胞对称和不对称分裂的选择机制仍不是很清楚。

According to the anisomerous differentiation of the needle leaves, the 4 or 5 needles per bundle could be formed under compatible condition, or affected by abnormity factors, such as mechanical, traumatic and insect pest injury

依据针叶原基的不对称发育和分化，如果温湿条件较好，或受到机械创伤，不对称的两个或三个针叶原基可以进一步分化成4个或5个针叶原基而形成4、5针1束。

The short shoot differentiation came from the lateral buds among the bud scales, in the initial stage, the lateral buds elongating, and then differentiating two "anisomerous"(one was small, the other was big) needle primordia in the elongating courses; the big one differentiating once more, and formed three needle primordia.

短枝的发育来源于长枝上芽鳞间的侧芽，在发育的初期，侧芽进行伸长生长，在伸长生长的过程中首先分化出一大一小&不对称&的两个针叶原基，大的叶原基进一步分化，形成三个针叶原基。

Intrinsic cell fate determinant Numb is the first protein found to be asymmetrically distributed during neural development.

Numb蛋白是神经发育中第一个被发现呈不对称分布的蛋白，是产生不对称细胞分裂的重要因素之一。

The general feature of deformation caused by the collision between two continents also reveals that, during the collision process, apart from a foreland basin and high mountains being formed, there is another compressive depression with an asymmetric structure developed on the side of the obducted plate, which is much easier to be formed when the dip angle of the collisional fracture zone is between 15° and 30° and is the deepest with a dip angle of 30°. This implies that the compressive depression is controlled by both subduction and obduction between two continents.

从大陆与大陆碰挂变形构造特征看，除发育前陆盆地－山脉系统外，在仰冲陆块一侧靠近造山带后缘还发育呈不对称结构的挤压性凹陷，当两个大陆板块碰撞断裂带倾角在15~30°时，该类型凹陷更容易形成，其中以30°倾角对应的凹陷最深，反映其形成可能是大陆碰撞过程中陆块之间相对俯冲和仰冲运动的综合结果。

The sequence analysis results of CO I and 16S rRNA gene showed that the much lower divergent level found among the ingroup samples in this study is more typical of what is seen among populations within species.

为了得到四种分析方法一致的沼虾属系统发育关系，我们构建了这四棵树的50%合一树，结果发现沼虾属可分为第二对步足左右不对称的类群和第二对步足左右对称的类群。

The discrete-element modeling is a new dynamic modeling method in structural geology and geophysics research. The authors built a discrete element model to simulate the evolution of the fault system in active salt domes. Results show that the fault system undergoes three stages: symmetric deformation stage, asymmetric deformation stage, and complete fracture stage.

离散元模拟是构造地质地球物理研究中一种新的动力学模拟方法，作者通过构建离散元模型，模拟了主动底辟盐构造断裂系统的演化过程，结果表明，该断裂系统的发育主要经历了对称变形、不对称变形、整体破裂三个阶段。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
