为了解新疆乌鲁木齐市维吾尔族 (简称维族 )、哈萨克族(简称哈族 )和汉族初一年级至高三年级学生近视眼患病状况 ,我们于 1999年进行了监测。1 对象和方法1.1 调查对象 以乌鲁木齐市初一至高三年级在校学生为调查对象 ,采取随机整群抽样方法 ,分别抽取维、哈、汉族学校各一
In order to understand the prevalence of myopia in the Uygur (Uygur), Kazakh (Kazak) and third graders in the first grade of Han nationality in Urumqi in Xinjiang, we conducted monitoring in 1999. 1 Subjects and methods 1.1 The survey respondents Urumqi City, freshmen to the third grade students in the survey, to take a random cluster sampling method, respectively, Victoria, Kazakhstan, Han schools each one
