  • length : n. 1. 長，長度，長短。2. （時間的）長短，期間。3. （賽艇的）一艇的長度；一馬的長度。4. 程度，范圍。5. 【板球】球程；投至適當距離的球。6. 【語言學】音長。7. 一段，一節。
  1. Chapter 4 : the paraxial propagation of partially coherent beams with the hermite - gaussian mode is investigated. the more generalized and simple expressions of the mean squared width and the beam quality factor of the beam with different mode order are obtained in terms of the cross - spectral density. our re - sults show that the higher order strengthens the variations of the mean beam width and the beam quality factor for partially coherent beams, and the relation between the two parameters of partially coherent beams is independent of the coherence length

    第四章：初步探索了部分相干厄米高斯光的傍軸傳輸，根據交叉光譜密度得到了其不同模階數的平均光束束寬和光束質量因子更一般的解析表達式，較高的模階數使得光束展寬得越快，光束質量變差，且這兩個光束參量的關系與部分相干厄米高斯光的相干長度無關。
  2. Abstract : one of the unsolved problems of the high power application of high temperature superconductors is how to lower the energy dissipation induced by flux motion. due to the extremely high anisotropy, small coherence length and weak pinning potential, the mixed state phase diagram which is tightly related to the flux dynamics becomes very complicated. a brief account is given of the field induced crossover of criticalities of energy dissipation, which has been observed in our recent sensitive electromagnetic measurement

    文摘:高溫超導體在強電方面應用的關鍵問題是如何克服磁通運動所造成的能量損耗.由於存在極強的各向異性、短的相干長度和小的磁通釘扎勢，因此與磁通運動緊密相關的混合態相圖變得很復雜.文章綜述了根據一系列靈敏的電磁測量所觀察到的磁場誘導的能量耗散行為的轉變
  3. As a new velocity sensor, fvisar has the merit of compact structure, short coherence length, easy to adjustment light path, any fringe constant and so on. the principle of fvisar analyzed from two different theories ( traditional coherent theory and doppler frequency shift theory ) lead to the same velocity equation which is the solid theory foundation of the fvisar design

    第二章分別從經典的光干涉理論和多普勒效應兩方面對fvisar的工作原理作了詳盡的理論分析，兩者得出了相同的速度計算公式，從而為全光纖速度傳感器的設計打下堅實的理論基礎。
  4. The dimension of the very large floating structures ( vlfs ) is usually more than 1km. the design of such giant structures must consider the spatial coherence of waves. crest length is one of the main parameters in wave coherence

    超大型海上浮體結構（ vlfs ）的尺寸通常以千米計，對于如此尺度的結構，作為主要環境因素的海浪必須考慮其在空間上的不均勻性。
