  1. By modeling of " y " - shaped junction of the compound river channel with an intersection angle 90, the flow velocity and water level at the junction were obtained by use of the acoustic doppler velocimeter ( adv ) and point gauges

    摘要通過製作交匯角為90的復式斷面河道" y "型交匯河口模型，利用三維聲學多普勒流速儀（ adv ）和測針獲取流速及水位數據，對支流河口處的水流流態包括水面形態、水流流速和水流分區進行分析。
  2. It is composed of thirteen functin ? components including two 3 - db y - junction power splitter, two directional couplers, two waveguide attenuators and one polarizer of waveguide itself. the prominent feature of the device is that it has a beat detection function with respect to the single y - branch mioc device, and it plays an important role in improving the inertial - grade and the high precision steady - aim system because of the beat detection function. farthermore it has direct influence on the improvement of the high flexibility, shockproof and overload - resistance for the steady - aim system

    器件的工作波長為1 . 3 m ，集分束器、合束器、起偏器/檢偏器、相位調制器、波導吸收器等十三個功能單元於一體，除了單y多功能集成光路器件具備的功能外，它還具有拍頻檢測功能，因而對提高慣導級和高精度穩瞄系統起著重要的作用，並直接影響著穩瞄系統的高機動性、抗沖擊力和過載能力的提高。
  3. In this paper, the foundamental principles of fd _ bpm ( finite - difference beam propagation method ) used to simulate and calculate the process of beam propagation is first introduced. then ， the theory of boundary condition is carefully presented. based on those theories mentioned above, a new kind of fd _ bpm arithmetic is brought forward. compared with the traditional arithmetic, this one has much more advantages. in virtue of the new arithmetic, author accomplished the whole simulating designs with two kinds of optical splitter ( stright y - junction optical splitter and sine - type optical splitter ), including propagation field simulating, vital parameter calculating, acquired some optimized waveguide parameters ， and finished the template by those results at last

    本文主要藉助這種改進的fd _ bpm演算法，對兩種結構的光分路器（直y型光分路器，上升正弦型光分路器）進行了器件設計的軟體模擬，包括對兩種結構光分路器傳輸場進行模擬，並對兩種結構光分路器的重要參數，如波導寬度，分叉角，縱橫比，損耗進行了模擬計算；得到了一些有價值的優化波導結構參數值，根據這些優化值設計製作了光刻模板。
