In this section , you can set a limit to the astrometric and photometric residuals of the reference stars 在這里,你可以設(shè)置一個有關(guān)參考星的天文測量和光度測量的誤差值。
The slight difference in response time of 1 msec would not be perceivable , and is likely due to measurement variability 響應(yīng)時間的差異只有1 msec ,可以無需考慮,而且可能是由于測量的誤差引起的。
On the other side , measuring errors of grounding resistance and solution of current voltage electrodes reversing has been compared with horizontal two layers and vertical delaminating ( three layers soil ) 比較分析了電流電壓極反向布置、在水平雙層和垂直分層或三層土壤結(jié)構(gòu)中接地電阻測量的誤差和解決辦法。
Based on the difference of measuring errors between spectrum and a single pulse , the article introduces a procedure which can improve the specification of non - linearity of commercial adc for spectrum measurement without channel - width - everaging circuit 摘要根據(jù)放射性能譜測量的誤差并不等于對單個脈沖測量的誤差的特點,提出一種先測出模數(shù)變換器的道寬,然后利用軟件方法進行道寬均勻的技術(shù)。
Both can improve the performance of state estimation . due to former condition , the method that the power equations are resolved directly to decide the placement is applied . the method , which reduce covariance errors of the measurements , is adopted under the later condition 前者采用使系統(tǒng)功率方程直接可解的方法確定pmu的測點布置;后者采用減小狀態(tài)估計量測量的誤差方差的方法宋確定pmu的測點布置。
Based on the error theory of point measurement are the identifying of the error range set , sketch of the error ellipse , analysis on displacement of the monitoring sites and error detection , providing a fundamental theory infrastructure for dynamic assessment of surface displacement and gray prediction 根據(jù)點位測量的誤差理論,確定定誤差值域范圍,繪出誤差橢圓;對各監(jiān)測點進行位移與誤差判別分析,為地表位移動態(tài)分析和灰色預(yù)測提供理論基礎(chǔ)。
Algorithms of insar data processing are also key factors , which related directly to the quality of dem and differential interferometric products , so it is necessary to develop advanced data processing algorithms and evaluate the accuracy of sar interferometry 數(shù)據(jù)處理算法的優(yōu)劣,直接影響到所提取的dem及差分干涉測量產(chǎn)品的質(zhì)量。因此,發(fā)展更為完善的數(shù)據(jù)處理算法及對干涉測量的誤差進行評估,是目前干涉測量研究的必需,也是干涉sar遙感創(chuàng)新研究的需要。
Those features have not been archived in domestic products of the same type , the two parameters of which are manually determined and the testing results could be quite different from person to person . the design discussed in the paper solved the problem by removing the factor of the interferences from the operators 目前國內(nèi)所有超生探傷儀對這兩個參數(shù)都是人工標(biāo)定,使得測量結(jié)果因人因時而不同,本設(shè)計對這兩個參數(shù)的自動標(biāo)定使得人為測量的誤差大大減小。
