将声学多普勒流速仪自动测量和分析系统应用于紊流边界层时均流速分布的测量，取得了较好的实验成果。
Results:The peak systolic velocity and the time average velocity of the central retinal artery of the affected eyes were lower than those of the patients healthy eyes(P<0 0001).
结果：患眼的视网膜中央动脉收缩期峰值血流速度、平均血流速度均低于对侧眼（P＜0．0001）。
We define average velocity as the position at time four seconds minus the position at time zero, 4 divided by four.
我们定义平均速度，是四秒时的位置，减去0秒时的位置，除以。
