尾数求差计算法及其在数字测量工程上的应用

A Tail-difference Algorithm and its Application in Digital Measure Engineering

报道了一种仅利用两个工整数的有限尾数求其差的计算方法，并介绍了利用此计算法设计的一种新型双频激光精密测量装置的硬件及软件．新装置不但电路简单可靠，且能实现高精度细分．

An algorithm which is valuable for digital measure engineering is introduced in this work. The difference of two infinite integers can be calculated from their finite tail ends. Hardware and software of a new Zeem Laser Measurement System device are also introduced using the mentioned algorithm. The new device is simple and reliable, and subdivision with high precision can be realized with it.
