The micrometer, which is also called a clock gauge, is a measuring instrument which is more precise than a common ruler. 分厘卡又叫千分表,是一种远比尺子精度高的长度度量工具。
Methods: 30 pieces of adult scapula specimen were studied. Linear measurements were made, while a micrometer measurements of thickness were obtained by a depth gauge. Angular measurements were made by using a goniometer to measure the nearest degree. 方法:对30侧成人肩胛骨标本进行测量,分别用千分尺及螺旋测微仪测量长度和厚度,用角度仪测量角度。
