When I put a test branch in the tube, I aligned the zero degree mark on one compass to match up with the first offshoot branch.
我把被测试的树枝放入这个试管，将一支量角器的零刻度线对准第一个侧枝。
They can go from 40 miles an hour to zero and land on a branch that’s moving, all in a couple of seconds.
在几秒种的时间里，它们便能将飞行速度从64公里每小时减为零，并落在树枝上。
Considering meshed network of distribution feed lines and node zero injection, we put forward a algorithm of status estimation based on branch currents.
提出考虑配电馈线环网和节点零注入的基于支路电流的状态估计算法。
