前言电位器旋转噪声的研究是涉及到我国电位器生产工艺与检验技术的一个迫切问题。长期以来,IEC 组织对轨道噪声的测试未做原则性修改,所推荐的测试电路一直沿袭至今。近十多年来,我国在噪声测试仪器的研制方面做了很多工作。对噪声机理的研究与工艺改革则更是大多数生产和研究单位着重进行的工作之一。从测试的角度很希望研制出在可比性和测试速度方面都得到提高的仪器。从工艺研究的角度也希望从测试实验中分析噪声机理找出提高质量的途径。本文是作者对轨道噪声特性的实验研究报
Preface Potentiometer rotation noise is related to China’s potentiometer production technology and testing technology an urgent problem. For a long time, the IEC organization did not make any fundamental changes to the orbital noise test. The recommended test circuit has been followed to date. In the past ten years or so, our country has done a lot of work in the development of noise test equipment. Research on the noise mechanism and process reform are even more important tasks that most production and research units focus on. From the test point of view, it is highly desirable to develop instruments that have improved both comparability and test speed. From the perspective of process research, we hope to find out the ways to improve the quality by analyzing the noise mechanism from the test experiment. This article is the author of the track noise characteristics of experimental study reported
