The characteristic parameters of effective debris in a ferrograph have been calculated in the present thesis, like area, perimeter, aspect ratio and granularity, in which some methods have been adopted such as smoothing, filtering and thresholding and so on, according to tribological theories and computer technologies and digital image preprocessing
本論文基於摩擦學原理和計算機技術，通過對鐵譜片進行數字化圖像預處理，採用對譜片圖像的平滑、濾波以及閾值二值分割等方法，計算出譜片中特徵磨粒的一些特徵參量，如面積、周長、粒度以及縱橫比等。 -
A lot of micro machining technologies are developed to fabricating memss. recently, lithograph of thick resist has been regarded as an effective and economical technology for manufacturing excellent high - aspect - ratio microstructures ( harms )
近年來，作為製作優質大高寬比微結構的厚層抗蝕劑光刻術以其工藝簡單、製作成本低等優點受到國際上廣泛重視。 -
We discuss the qcse of the impurity in the finite square qwws considering impurity position, and raise a point of the qcse under the influence of the masses mismatch and the aspect ratio of the quantum well wires. without considersion of the mismatch of the effective masses between the well and barrier, we obtain the conclusion as follows : ( l ) the first band energy of the electron is decreased under the electric field
在前人工作的基礎上，我們在有效質量近似下討論了外加電場下有限深方形gaas ga _ （ 0 . 63 ） al _ （ 0 . 37 ） as量子阱線的雜質態和雜質的stark能移，並把我們的結果與前人的結果進行了比較。 -
On the calculation, we can hold the conclusion that the two kinds of compensators have no distinct difference at the technical aspect under circumstances of two - phased compensation. the effect of decreasing negative sequence current and harmonics ratio is indistinct, however, both are effective in increase power factor
通過模擬發現，這兩種補償方案在技術方面的差別不大：兩相補償模式下，在降低負序和濾波方面，效果都不明顯；對提高功率因數的作用顯著。
