摘要
对杨氏模量测量中的方法误差和非标准状态造成的误差进行了定量分析,指出系统应处于的标准状态,并对传统仪器进行了有效改进,使测量精度提高.
A quantitative analysis of the experimental error of Yang抯 Modulus determination and error under nonstandard experimental conditions is presented. It is pointed out the system should be under standard condition. The accuracy of the measurement has been reinforced because of the effective improvement of traditional instruments.
