In PIV measurement, 2-d data collection techniques were used to gain vector field of flow around vegetation with different vegetation rigidity under similar flow conditions.
采用PIV激光图像速度场仪，选择二维相关采集测量，得到在相似水流条件下不同刚度植被周围的流场矢量图。
The unified mode can be decomposed into strip-map mode, spotlight mode, sliding spotlight mode and beam scanning mode, and each correspondingly has a simplified 2-d data collection equation.
从统一工作模式可以分解出条带扫描模式、聚束模式、滑动聚束模式和光束扫描模式，及其相应的简化二维数据收集方程。
