游标卡尺得到十分广泛的应用,并非由于它的历史悠久,而是由于它的结构刚性好,适用面广,而且相对其重量而言,其测量范围较大。卡尺的这些特性便使其缺点,如产生第一级测量误差和游标上读数费时等,退居到第二位。如果将新、老卡尺加以比较,则可发现,其基本结构实无多大变化。同时,也看不出在最近的将来卡尺出现新结构的征兆。但是在过去年代里,人们还是做了许多旨在提高测置值读数精度和速度的研究工作。到目前为止,所发展的新型和变型品种的卡尺,主要用作特殊测量,例如测量齿轮、螺纹和孔距等。
Vernier caliper has been widely used, not because of its long history, but because of its structural rigidity, wide range of applications, and relative to its weight, its measurement range. These characteristics of the caliper make it disadvantageous, such as the first-order measurement error and the time taken to read the cursor, etc., retired to the second place. If the new and old caliper to be compared, you can find that the basic structure of real little change. At the same time, we can not see signs of a new structure in the caliper in the near future. However, in the past few years, many researches have been done to improve the accuracy and speed of measuring value reading. To date, calipers of the new and variant types developed have been used mainly for special measurements such as measuring gears, threads and hole pitches.
