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(duì)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(chǎng)的各種測(cè)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(gè)校正點(diǎn),測(cè)試表所顯示的阻值便會(huì)與應(yīng)用電阻值作一比較,而測(cè)試表的輸出電壓亦同時(shí)受到測(cè)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(duì)鉑電阻溫度計(jì)的要求,通過(guò)研究鉑電阻溫度計(jì)的測(cè)溫特性,提出了提高鉑電阻溫度計(jì)測(cè)量精度的方法,并給出了在溫度校準(zhǔn)點(diǎn)的測(cè)量不確定度。
