摘要:PROBLEM TO BE SOLVED: To obtain a method of detecting the slot shape of a slot rod which can measure the inversion angle and the twisting pitch of an SZonSZ slot. SOLUTION: The average of the inversion angle of continuous short period SZ twist is calculated, and the inversion angle of a short period SZ twist is detected. Moreover, the maximum inversion angle and the minimum inversion angle of the short period SZ twist are detected, the minimum inverting angle is subtracted from the maximum inverting angle, and the average inversion angle of the short period SZ twist is furthermore subtracted and thereby, the inversion angle of the long-period SZ twisting is detected.
