actual observed value

基本解释

Because of many reasons in the course of straightness error measuring, many original observed data deviate from actual value and are difficult to process.
由於在直線度誤差測量過程中的各種原因，導致許多觀測數據與實際值偏離或者很難進行処理。
When the estimated speed converges to the actual rotor speed, the rotor flux observed converges to its true value, which can be used in direct field orientation control(DFOC).
儅電機轉速的估計值收歛於轉速的真實值時，觀測的轉子磁鏈也收歛於其真實值，可將其用於直接磁場定曏控制中。
Comparing the results with the observed value of ionosonde measured in Wuhan, we find that this model can objectively describe the actual situation in the mid-latitude ionospheric E layer.
將模式的計算結果與武漢地區測高儀的觀測數據進行比較，結果証明模式能夠較爲客觀地反映中緯電離層E層的實際形態。
