The segmentation and feature description of a 1d curve is very simple . it is very easy to separate a signature into several curves with different stableness by this 1d description . in the verification , different curves are given different weights 对于一维曲线,在分段和特征描述方面更加简单,而且通常手写签名在x和y方向的稳定性是不相同的,通过一维的描述可以很容易地将签名分解为不同稳定性的特征曲线,并在签名鉴别中赋予不同的权重。
When x direction seismic waves were input , the y direction dynamic displacements on the symmetry surface were nearly zero . but when three directions seismic waves were input , the y direction dynamic displacements on the symmetry surface increased rapidly to the same grade of x direction . so the three directions seismic waves were necessary for the dynamic analysis of the structures 输入x方向的地震波，在结构两个对称面上的节点沿y方向的动位移几乎为零，当输入三维地震波时， y方向的动位移则明显增大，达到与x方向同一量级，因此，对结构动力响应分析时，应输入多方向地震波，才能真正掌握结构的响应。
The computational results of the particle images are agreement with the simulated datain reasonable , the most absolute difference of the displacement is 0 . 6671 pixel at the x abscissa and 0 . 7928 pixel at y abscissa ; the computational results are equal to the data form the algorithm of particle brightness - distribution pattern tracking ( the conventional cross - correlation algorithm ) at voluminous points , their discrepancy is only one pixel at few points , mostly in boundary area 西安理工大学硕士学位论文最后，在visualfortran环境下给出了这种算法的具体实现，处理模拟粒子图像的结果与模拟数据比较吻合，最大位移绝对误差在x方向是0 . 6671像素，在y方向是0 . 7928像素;计算结果与示踪粒子灰度分布模板法(基本的互相关法)在绝大部分点是相同的，只在少数点相差一个像素，而且大多出现在边界区域。
We propose a novel controllable atomic beam - spiller based on the uccc and discuss the splitting mechanism of the guided atomic beam in the beam splitter from two aspects of the magnetic - field distribution and the trace of the guiding centers . the splitting ratio of the beam splitter can be adjusted by adding a homogeneous bias magnetic field along the y - direction , and the relationship between the splitting ratio and the additional bias field is analyzed 本文提出了一种采用在y方向上加一偏置磁场来实现分束比可控的新颖原子分束器，并从磁场分布和导引中心轨迹两个方面，详细分析和讨论了基于u -型载流导体所构建的原子分束器的分束机制。
