风矢 meaning in Chinese
barbed arrow
wind arrow
Examples
- By simulating mathematically on frequency and on space , we can find the average speed of space field and the average speed of frequency field that is weighted by amplitude , and analyse their relation , and analyse the meaning of space speed variance x and frequency speed variance v . in the fourth part , how to ensure the height of cloud is introduced , and basing on the theory of wind field continuity , the height updating quality controlling is introduced . in the fifth part , the system of cloud wind is introduced , we tracked cloud - motion of consecutive satellite images with one - minute interval by the 1 - d fourier analysis technique and the two - dim fourier analysis technique and the fft analysis technique , and dispose them with quality controlling . in the sixth part , we summarized our research and put up with shortages of this article
模拟模块内各点的速度线性变化时，得到空间域平均速度以及频率域以振幅为权重的平均速度，分析了空间域平均速度和频率域以振幅为权重的平均速度的关系，并揭示空间域的平均速度的标准差_ x和频率域的振幅为权重的平均速度的标准差_ v的意义，以及它们之间的关系；第四章介绍了云迹风系统的高度指定以及风矢高度的划分，并根据风场连续性原理，介绍了高度调整法的质量控制；第五章介绍导风系统的流程，选择了三个时刻的ir云图，分别用一维傅立叶相位法、二维傅立叶相位法和快速傅立叶算法计算一个风场个例，并对所得风场进行质量控制，并给出风场图；第六章进行研究总结，指出不足和有待于进一步研究之处。
