axial length
6.reviewed the effect to the displacement of the anchorage along the main cable direction and the stability of the surrounding rock ,following the variation of the design parameter(the blinding power c、 the tilt angle of the anchorage α、 the axial length of the anchorage L、 the magnified angle of theanchorage y ,etc.)
7.Methods 32 eyes in 17 patients with-9.75 ～-21.625 D high myopia were implanted with Phakic 6/Verisyse anterior chamber lenses. The axial length and anterior chamber depth were measured with a Zeiss IOL-Master before and 1 month after surgery. Statistical analysis was performed to determine the correlation between the measurements before surgery and after surgery.
9.Aiming at the defect problem of stock shearing cutting,a comprehensive geometrical analysis of radial clearance,axial clearance,bar diameter,and contact length of cutting edge with the bar,which affect shearing quality in the process of cutting,is presented in this paper where, star ting with the considerationof crack spreading, it is taken as a premise that the cracks formed at the both cutting edges must encounter with each other to ensure cutting quality.
