span error 中文意思是什麼
span error
解釋
量程誤差-
That widely quoted range looks like an error bar - - a span of values with a well - defined probability of encompassing the true value - - but it is actually just a grab bag of model results
這一廣泛引用的升溫范圍就像一個誤差表? ?在這些具有一定可能性的估計值中包含有真實的數值? ?但實際上它只是眾數的集合。 -
The main features of the frf of long span runyang bridge, which has 1 024 dimensions, can be extracted by 27 or 17 principal components, and the reconstruction error is acceptable
對于大跨斜拉橋（潤揚長江大橋北漢斜拉橋）的1024維頻響函數可以僅用27個（或17個）主元來提取其主要特徵，精度可滿足工程需要。 -
Measurement test the speed with untouchable measurement, touchable measurement and all kinds of measurement speed sensor have been analyzed from economy, environment, precision, life - span, etc. compari ng relevant error that the measuring system produces at the same time, to examine combined harvester complete machine request of performance of producing. make relevant error meet the precision request, and can reach the best state
對接觸性測量和非接觸性測量兩類測速方法及各類測量速度傳感器從經濟、環境、精度、壽命等方面進行了分析，同時對測量系統所產生的相關誤差進行比較，針對測產型聯合收割機整機性能的要求，使相關誤差滿足其精度要求，並且能夠達到最佳狀態。 -
