THE RESULTS OF ONE - SITE VERSUS TWO - SITE APPROACHES IN COMBINED SURGERY (PHACOEMULSIFICATION AND TRABECULECTOMY)

Purpose: To compare the results of combined surgery (phaco-emulsification and trabeculectomy) through one site and two site incisions in cases who have both cataracts and glaucoma. Methods: 48 eyes of 41 patients who have been operated between 10.06.1999 and 26.03.2002 in our hospital were included in the study. In group I combined surgery was performed in 23

Methods: Clinical data of all AGV implanted patients in the Glaucoma Department of Beyoglu Eye Educaion and Re-

作用在防抱制动系统上的外转矩

本文研究了采用一个附加的驱动力矩作用于一带 ABS系统的控制机构来缩短制动距离的可能性。在该 ABS的控制周期内 ,只有减小制动压力才能使锁止轮再加速 ,当在制动压力比较低的阶段可采用一外加牵引力矩来缩短加速时间。可用车辆发动机或一个附加电机作为一外加牵引力矩源。可以用一个数字模型来研究该系统缩短制动距离的可能性。采用一个仿真模型来分析该附加加速力的影响 ,并获得可缩短制动距离达到 1 0 %的结论。
