| Abstract: | For evaluate uncertainty of calibration specification for pressure reference leak, establish math model, ana- lyze the influence and the sensitive of uncertainty, and evaluate the uncertainty caused by thecalibration apparatus and re- peatmeasure, comparatively extendable uncertainty of calibration specification for pressure reference leak could be gained. Through experimentation, a demonstration of calibration specification for pressure reference leak is given. |
