| 摘 要： | 我国原有铀矿γ测井模型标准铀含量上限为1.09%,应用其校准的γ测井仪对高品位铀矿的测量结果曾饱受争议。在2014年研建高品位(1.83%、5.09%)铀模型后,用其对γ测井仪的计量特性在进行了试验验证后,结果表明仪器死时间和铀含量灵敏度没有显著变化,说明γ测井仪在铀含量5%以内的测量结果仍然可靠。

| Abstract: | High resistance meter and digital source-meter have a wide application in semiconductor industry. But commercial high value resistance whose accuracy is (±1.0×10-3~±1.0×10-2) cannot meet the need of traceability of resistance parameter for high resistance meter and digital source-meter. The paper demonstrates a high accurate calibration method for commercial high value dc resistor, realized by a comparator bridge composed of two multifunctional calibrated voltage source and a zero-current-meter. A calibrated system is set based on the method, and the measurement uncertainty is 3.0×10-5~8.0×10-4, whose accuracy can meet the calibration need of most of high resistance measurement instrument. |
