One of two sperm get into an archegonium and fused with egg. The nucleus of fertilized egg began to divide, and the walls were formed after the third division. The eggs without fertilization divided two times and then disappeared.

雄配子体产生的两个精子中的一个进入颈卵器与卵细胞结合形成受精卵，受精卵核到第3次分裂形成细胞壁，没有受精的卵细胞还要进行两次有丝分裂后才消失。

In this paper, after the introduction of the basic concepts and the main results on K〓 theory, relative K〓 theory and the theory of classical groups of degree 2 which is related to K〓 theory, we study the problems of the computation of K〓 for the ring of integers of quadratic imaginary fields, examples of subrings of quadratic fields which are not universal for GE〓 and generating set of the Cokernel of the canonical homomorphism from K〓 to K〓.

本文在介绍了K〓理论和相对K〓理论以及与K〓理论有关的2阶典型群的基本概念及主要成果之后，对于虚二次域代数整环的K〓群的计算，非GE〓泛的虚二次域的子环以及K〓到K〓的自然同态的余核的生成元集等问题进行了研究。

Divide, and each sister chromatid moves to one of the poles of the spindle.

第二次核分裂开始于分裂中期，子细胞中染色体重新排列在赤道板上。

Cell cycle is the cell through a series of orderly changes in the cells to achieve cell growth and proliferation process of cell cycle regulation and individual development, differentiation, growth, regeneration, aging and cancer cells is closely related to eukaryotic cell cycle mitosis two key processes, namely DNA replication and sister chromatid evenly assigned to the sub-cells.

细胞周期是指细胞通过一系列有序的细胞内变化，实现细胞生长和分裂增殖的过程细胞周期的调控与个体发育、分化、生长、再生、衰老以及细胞的癌变密切相关真核细胞有丝分裂周期有两个关键的过程，即DNA的复制和姐妹染色体均衡地分配到子细胞中。

Some concepts in quantale, such as c-nuclei, r-nuclei, closed map closed filter were introduced and Some properties of these new nuclei are discussed.

幂等左侧Quantale是单纯Quantale当且仅当它是离散一致简单Quantale。二。研究Quantale中的核映射和闭滤子。

Thus, codon usage bias of nuclear genes appeared to be affected by translational selection.

因此，核基因的密码子使用偏好性受到翻译选择的影响。

It activates many virus and mammalian cells'promotors through the binding with GC/GT box, deciding the efficiency and specificity of the transcription of promotor. Sp3 gene turning out both activating and repressing function, even to the same gene, it can also develop the different function in different period, and therefore has got the important meaning to numerous genes of human body.

Sp3（Specificity protein，Sp3）基因是一种核转录因子，属Sp家族成员之一，是继Sp1后发现的具有与之相同的DNA结合区的转录调节因子，近年来发现它对众多基因均具有调节作用，它通过与GC／GT box结合，激活许多病毒和哺乳动物细胞的启动子，决定启动子的转录效率和特异性。

In this paper, the image intensity surface for the neighborhood of every pixel is well-fitted by the Least Squares Support Vector Machine, and the gradient and the zero-crossing operators are deduced from the LSSVM with the Radial Basis Function kernel function, as an example.

摘要该文利用最小二乘向量机对原始图像每一像素的邻域作灰度曲面的最佳拟合，并以径向基核函数为例导出了图像的梯度算子和零交叉算子。

A sequence of three adjacent nucleotides in transfer RNA designating a specific amino acid that binds to a corresponding codon in messenger RNA during protein synthesis.
