摘　　要：随着我国衡器和自动称量技术的发展,各种电阻应变式称重传感器的应用也更加普遍。传感器的结构及型式,由常温至高温,由传统的模拟式也逐渐进入数字式。但是人们关心的仍然是传感器的性能及其稳定性。本文试以应变片的测量原理,从应变传递机理方面,把国内外学者在这方面的研究成果介绍给大家。Following the development of weighing instrument and automatic weighing technology in China, a variety ot strata gauge load cell applications are more common. Structure and type of load cell from constant temperature to high temperature, from the traditional analog gradually into the digital. But the people are still concemed with load cell in performance and stability This article introduces the research of domestic and foreign scholars in this area, form the aspects of strain gauges measuring principle and the strain transfer mechanism.
