《计量技术》先后于1988年第10期刊登了王宏涛的(用“零位偏移法”提高千分尺的使用精度)及1979年第3期高重庆的(用零位补偿法减小千分尺的示值误差)二文。内容是用增大千分尺零位误差的方法来减小千分尺的示值误差。然而千分尺不允许有零位误差存在,故该法不能达到目的。笔者队为:为了某一尺寸的实际需要,可以用相同尺寸的量块进行校对,但这时该尺应作为专用量具而不是通用量具来使用。
“Metrology Technology” published Wang Hongtao in the tenth issue in 1988 (using the “zero offset method” to improve the accuracy of the micrometer), and in 1979, No. 3 High Chongqing (using the zero compensation method to reduce the micrometer Value error) Erwen. The content is to increase the micrometer zero error method to reduce the indication error micrometer. However, the micrometer does not allow zero error, so the law can not achieve its purpose. The author team: For the actual needs of a certain size, you can use the same size of the block for proofreading, but then the ruler should be used as a special measuring tool instead of a universal measuring tool.
