SS-Y伸缩仪灵敏度、分辨力、传递函数测试方法研究

摘要

结合大量实验数据,通过定量输入输出测试、固体潮推算测试和阶跃输入响应测试3种方法分别测试分析了伸缩仪灵敏度、分辨力和传递函数的特性,结果可知,拟定的方法可行.%The development and application of extensometer have been for almost 40 years, it always focus on how to improve the precision but ignore its own characteristics. The SS-Y extensometer' s measuring sensitivity,resolution and transfer function are analyzed quantitative input-output test,reckon test of earth tide and step-input response test. The results show the methods are feasible.
