Measuring method for differential coefficient of expansion and the standarduncertainty is introduced as well.
同时介绍了微分膨胀系数的测量方法及其测量不确定度。
2
Result: Uncertainty in each ponderance were analyzed and put forward combined standarduncertainty resides of the method.
结果:量化各不确定度分量,提出了该法的合成不确定度评估结果;
3
The influential factors of the standarduncertainty are analysized systematically and evaluated in detail to the volume of the volume-weight instrument.
