速度剖面图 meaning in Chinese

velocity profile

The tool software is visual c + + 6 . 0 . the software includes three main parts : ( 1 ) pre - processing , means carrying out denoising operation to the images with morphological filter : ( 2 ) after this , one of three kinds of methods can be selected to do the processing operation . ( 3 ) post - processing . this process is the complementarity to the step 2 . velocity profiles and the picture of vorticity correspond to the flow field can be got in this step and the processed data can be saved too
本软件主要实现的功能包括： ( 1 )用各种形态滤波器对实验中所获得的粒子图像进行去噪的预处理操作； ( 2 )对去噪后的图像采用三种方法进行处理操作，给出所测流场的速度矢量图； ( 3 )进行后处理，包括给出过滤后的速度矢量图、速度剖面图、涡量图和进行数据保存等。
