查询词典 pattern identification

It is a measurement method following the diffraction and interference theory of the point light source. The phase message of interference pattern was obtained by the Fourier transform pattern analysis method. And the xyz-coordinates of the two point diffraction sources were calculated by the modified Newton method based on the Broyden-Fletcher-Goldfarb-Shanno algorithm.

基于傅里叶变换的点衍射干涉测量术是一种建立在点光源衍射干涉理论基础上的测量方法，它采用傅里叶条纹分析方法来求解干涉条纹的相位分布，运用基于BFGS的拟牛顿算法进行三坐标的迭代计算，确定点光源的三维空间坐标。

Sign pattern A is a SAP if every monic real polynomial of degree n can be achieved as the characteristic polynomial of a matrix with sign pattern A.

若给定任意一个n次首一实系数多项式f，都存在一个实矩阵B∈Q，使得B的特征多项式为f，则称A为谱任意符号模式。

An n×n sign pattern A is a spectrally arbitrary pattern if for any given real monic polynomial f of degree n, there is a real matrix B∈Q and B has characteristic polynomial f.

设A为n阶符号模式矩阵，若对任意给定的一个n次首1实系数多项式f，都存在一个实矩阵B∈Q，使得B的特征多项式为f，则称A为谱任意符号模式。

The relationship among the moving border, size of thawing hole, size of grain, type of grain and the height of grain is studied. The relationship between the size of thawing hole and the released quantity is studied by plane pattern and stereo pattern.

The spatial distribution parameters, parameters of Iwao model and Taylor's power law were used to analyze the spatial pattern of the lavae of Argopistes tsekooni Chen in glossy privet. The results showed that its spatial pattern was negative binomial distribution, with colony as its basis component and its colony distribution was random.

应用空间分布参数、Iwao回归法和Taylor幂法进行分析表明，女贞瓢跳甲幼虫在大叶女贞上呈负二项分布，分布的基本成分为个体群，且个体群为随机分布。

And its developmental expression pattern showed that AmphiRab23b was expressed in the differentiating neural plate and alimentary canal, as the same as the expression pattern of the homologous vertebrate genes, which suggested that AmphiRab23b may function in the development of nervous system and alimentary canal.

时空表达的研究结果进一步显示，AmphiRab23b基因在胚胎发育中的神经板和消化道中表达，与其脊椎动物同源基因的表达模式相似，这说明该基因可能对文昌鱼神经系统和消化道的发育有重要作用。

The releasing pattern of secretory granules or polypeptide hormones of neurohypophysis involves a whole-releasing pattern together with granular membrane. After released into perivascular space, they enter easily into cerebrospinal fluid via interspace of tissue and epithelial openings rather than into blood circulation through the walls of capillaries, and then into the cerebrospinal fluid.
