场频 meaning in English
field frequency
field rate
Examples
- 3 . scan frequency is over 200hz : using over 200hz frame scan frequency will have good vision effect
3扫描场频大于200赫兹：使用帧扫描频率200hz以上，有很好的视觉效果，人肉眼几乎 - Prediction of hydrodynamic pressure . the thesis presents a practical engineering method to predict the hydrodynamic pressure on instantaneous wet ship surface
关于水动压力预报：本文提出了基于二维扰动流场频域稳态解的一种预报船体瞬时湿表面压力分布的工程实用方法。 - This system works under the pal service pattern , and it ’ s rate of field repetition is 50hz . the frequency of image sampling is 27mhz ; the size of image display is 512 by 64 ; the picture demonstration is clear and stable
本系统工作在pal制式下,场频50hz ,图像采样频率27mhz ,图像显示大小为512 64 ,显示画面清晰稳定。 - Scanning frequency has reached over 240hz which makes the menu stable and no flicker . in using actually , we use vidicon shoot the display screen . and then we can observe the photo is very clear from the vidicon
2扫描场频达到了240hz以上，画面稳定无闪烁，在实际应用中，用摄像机拍摄显示屏，摄像机中观测到的图象十分清晰，没有同步滚动条，若现场有电视转播，显示屏不会影响转播画面的质量。 - Employing the interlaced scanning , current tv system can compress the frequency band of tv signal effectively and facilitate transmission . but this method reduces the scanning lines of pictures and the frequency of the field . it leads the pictures displayed on tv to have such disadvantages as large area flicker , edge flicker , interlace flicker , raster visibility and creeping line etc . to satisfy people " s vision feeling better , the big - screen , multi - function and high quality tv - set have been made great progress
现行的广播电视系统由于采用隔行扫描方式，从而有效地压缩了电视信号的频带，有利于传输；但由于这种方式使得图像的扫描行数少，场频低，导致了重显的电视图像有大面积闪烁、边缘闪烁、行间闪烁、行结构可见及行爬行等。
