| 摘 要： | 由于晶须中螺旋位错的存在,在宏观上将使晶须扭转一定的角度。本文提出了两种较精确的晶须扭转角度的测量方法,且所测的都是单晶晶须的局部扭变。其中方法一所测结果的有效位数可达三位。

| Abstract: | Due to the screw dislocations presented in the crystal, generally. The single crystal whiskers were turned an angle. In this paper, two precise methods are posed to measure the turning angles here. The local twist of the single crystal whiskers can be measured accurately in those methods. In one of them, three significant digits can be reached. |
