For simplicity , we assume e to be in the x direction and to vary sinusoidally in the y direction
In the preceding example , the world transformation is a translation 100 units in the x direction and 50 units in the y direction
The transformation first scales by a factor of 0 . 5 in the y direction , then translates 50 units in the x direction , and then rotates 30 degrees
Suppose you want to start with the point 2 , 1 , rotate it 90 degrees , translate it 3 units in the x direction , and translate it 4 units in the y direction
The following example creates the matrix of a composite transformation that first rotates 30 degrees , then scales by a factor of 2 in the y direction , and then translates 5 units in the x direction
The following illustration shows an affine transformation rotate 90 degrees ; translate 3 units in the x direction , 4 units in the y direction expressed as multiplication by a single 33 matrix
Based on this , the optimum operating mode of ln anisotropic one - dimension aeo device is determined as : light promulgates along z axis , ultrasonic wave promulgates along x axis , and direct current electric field is loaded along y axis
用y方向造句挺难的，這是一个万能造句的方法
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
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
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
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
By using auto - adjusting boundary conditions and the method of three cubed spline curve fitting , the system software can recover both of the horizontal and vertical beam profile . the measurement system can also measure the beam landing screen error of cpt . it provides a important measurement and analysis tool to improve the performance of electron gun and dy , and improve the definition of cpt
