doppler spectrum meaning in English
非常多，艺术设计多普勒频谱
Examples
- The energy centrobaric method is made use of correcting the doppler spectrum , the simulation predicted value of the target velocity is obtained
用能量重心校正法对多普勒频移校正，进而得到物体的运动速度的模拟计算值。 - This paper introduces several methods retrieving wind direction from hf radar echo doppler spectrum and analyses the feature of those methods
本论文介绍了现有的从高频雷达回波多普勒谱中提取风向的几种方法，分析了这几种方法的不足之处。 - One of these problems is the broadening of the first order sea echo doppler spectrum , which most likely swamps the targets spectrum
本文针对这样一个关键性问题?展宽海浪谱中信号检测问题展开研究,即如何应用超分辨谱估计技术来实现目标的检测与分辨。 - 2 . respiratory variation index ( rvi ) in normal man pulsed - wave doppler spectra of the four cardiac valves were recorded and compared with sequoia 512 and acuson 128 xp / 10 in 79 normal subjects aged 18 to 70 years
正常人rvi值范围的测定79名健康志愿者，采用sequoia512和acuson128xp 10彩色电脑声像仪，记录各瓣口血流速度、同步心电图和呼吸曲线。 - Results the doppler spectrum of the combined motion of the chamber and the fluid was the vector sum of their doppler signals . conclusion cardiac motion alters the doppler signal derived from blood flow and this effect should be considered in the doppler flow velocity measurement
结论通常所谓的血流速度频谱实际上是血细胞在心脏内流动速度和心脏运动速度的矢量和，即两项运动的复合频谱，所以，为减少误差，在用多普勒血流速度频谱测定血流参数时，应考虑校正问题。
