变速齿轮原理、研究、编程编写、是很好的学习材料-Gear theory, research, programming, writing is a very good learning materials

汽车里程表调教仪器随着电子科技的进步，现今的汽车仪表都趋于电子化了。早期的机械软轴的里程表几乎已经消失了，取而代之的是电子式的里程表和液晶显示屏，过去可以通过拨数码齿轮的方式调整里程表，现在这些方法都行不通了！-Automobile odometer as electronic instrument has the progress of science and technology, the current car instrument all tend to electronic. Earl

基于可变转矩与速度的新型齿轮故障检测系统，本文为齿轮故障检测的英文原文.-Based on the new gear fault detection system variable torque and speed, this article is the English original gear fault detection.

一个典型的文章齿轮啮合的外文文献，可以供大家一起学习交流。-A typical article gear meshing of foreign literature, can communicate for everybody to learn together.
