概算計量
  • approximate : vt 1 使接近。2 接近；走近。3 近似，約計。4 模擬。5 估計。vi 近於。 His income this year approxima...
  • measurement : n. 1. 測量，計量，量度。2. 份量，尺寸，大小，寬度，厚度，深度（等）。3. 測量法。 measurement goods （按體積、容積計算的）體積貨物。
  1. In the amsjpda, targets are divided into approximate clusters. different from the cluster in msjpda, the approximate cluster has one " center target " and the other targets are its " neighbor targets " if there is at least one measurement inside the intersection of the validation gates of the center and the neighbor

    在近似法中目標被分成不同的近似聚，與傳統聚不同的是近似聚中有一個中心目標，聚中其它目標與中心目標的相關門間有交疊，且交疊區中至少有一個公共量測。
  2. According to the principle of correlation detection, an automatic measurement system for extinction ratio of polarizer consisted of monochromator and dsp lock - in amplifier and compurer is designed not only to eliminate the influence on measurement accuracy caused by drift of intensity of light source but also to obatain approximate extinction spectrum

    摘要基於相干檢測原理設計了一套由單色儀、數字鎖相放大器和計算機聯合使用的透射式偏光鏡消光比智能化測試實驗系統，採用雙頻雙光路分光單探測器接收鎖相放大器分離信號比對法進行源補償測量，克服了光源光強漂移所帶來的影響；實現了可見光區消光比的精確自動測量，而且可以測得近似的消光光譜。
  3. The same conclusion as derived from the original pda under approximate condition is concluded this way without any approximations. the second method is the instant - state performance prediction based on the hyca method. this method not only gives the off - line recursive error variance relation, but also gets a series of performance measurement such as track life

    然後應用兩種方法對其進行性能估計和預測，一是基於riccati方程的穩態性能估計，其結果與pda演算法近似條件下得出的結論相同；二是基於hyca方法的瞬態性能預測，不僅給出了誤差方差的離線遞推關系，而且得到了航跡壽命等一系列性能指標的估計值。
  4. The quarter turn graduations on the sleeve, with the scribed line on the stem, provide for approximate flow measurement

    在套筒上四分之一轉的刻度，以及閥桿上的刻痕，顯示大約的流量測量。
