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。
The method of difference, geometry-free combination, melbourne-wubbena combination for cycle slip detecting are analyzed in this paper. Then the test of cycle slip using COMPASS observations is made.
目前，有很多种用于周跳探测的方法，其探测原理都是建立在粗差理论基础上的，首先由观测数据组成适当的检验序列，使得周跳在该检验序列中以粗差的形式表现出来；
