“海上皇后”船，相对风向和风速是多少度，几节？
M/V Sea Queen, what is relative wind direction in degrees and knots?
基于开关式相对风向传感器，提出一种固定周期采样、变周期控制的风向随动模糊控制系统。
Based on switch mode sensor of relative wind direction, we present a kind of tracing wind fuzzy control system with constant sample cycle and variable control cycle.
林带边粒径分布测定结果表明：下风向处较大粒径颗粒物的相对含量比上风向处小一些；
The results of measurements for the particulates radius distribution showed that the relative content of the bigger granule matters in the forest-leeward was smaller than that in the forest-windward.
