In order to improve calibration precision without increasing computation complexity , tsai ' s two - stage calibration technique with calibration points in multiple planes is refined 為了進(jìn)一步提高標(biāo)定精度,對利用多平面標(biāo)定點(diǎn)的tsai的兩步法進(jìn)行了改進(jìn)。
Because the most of measures of the traffic accident are on the road , the subject adopt 2 - d analysis method . this decreases the number of the calibration points greatly 由于道路交通事故現(xiàn)場的各種測量多是在路面上進(jìn)行,故在本課題中,采用二維分析法。
At each calibration point the indication on the tester will be compared with the value of the applied resistance and the output voltage of the tester will also be measured 每到達(dá)一個校正點(diǎn),測試表所顯示的阻值便會與應(yīng)用電阻值作一比較,而測試表的輸出電壓亦同時受到測量。
The figure below shows the magnitude of the error that results from a 1 % error in recording either i0 ( intensity of fluorescence at zero - pressure oxygen ) or the intensity at the high calibration point 下圖表明了誤差值,記錄中結(jié)果為1 %誤差或i0 (在零壓力氧下熒光強(qiáng)度)或在高校準(zhǔn)點(diǎn)下的強(qiáng)度。
Based on the verification regulation of prt , this paper studies the temperature characteristics of prt , suggests a method of improving the accuracy of measurement and supplies the uncertainty of calibration point 摘要分析了檢定規(guī)程對鉑電阻溫度計的要求,通過研究鉑電阻溫度計的測溫特性,提出了提高鉑電阻溫度計測量精度的方法,并給出了在溫度校準(zhǔn)點(diǎn)的測量不確定度。
