Second, the mode fields of a strip waveguide and some slab waveguides have been simulated by applying finite - difference time - domain ( fdtd ) method. the curvature radius ; vicinity coupling ; transition loss and power attenuation of a s - shape bend waveguide have been analysed numerically by employing wide angle finite - difference beam propagation method ( fd - bpm ), as well as the coupling loss of optical fiber and waveguide. in addition, the framework of the s - shape waveguide laser has been
其次，應用時域有限差分法，結合波導模式理論對條形與平面波導進行了模場模擬;應用廣角有限差分光束傳播法，對s形彎曲波導的曲率半徑、鄰近耦合、過渡損耗、功率衰減以及波導與光纖的各種耦合損耗進行了數值分析，並在此基礎上，對s形波導激光器的結構作了初步設計。 -
Because numerous mega - columns and mega - beams of mega - frame are thin - walled beam, hence the torsion can " t be neglected in structural calculation, and so in the calculation of structural overall stability, the coupling of bend and torsion can " t be neglected. the second is the thin - walled beam with opening section element which be considered effect of axis force and the coupling of bend and torsion
由於巨型結構中許多巨型柱和巨型梁為薄壁桿件，所以在結構計算中就不能忽略扭轉，同樣在結構的整體穩定性計算方面就必須考慮彎曲與扭轉的耦合，所以作者推導了開口薄壁桿件在考慮軸力效應、彎曲與扭轉耦合時的單元。 -
It analyses static errors and dynamic errors, calculates vehicle plane every parts static and dynamic steel and bend distortion effect. it discusses testing means and testing equipment to oscillation, puts forward disposal means to oscillation data, fetches oscillation model of vehicle plane, does predigestion and coupling to all kinds of oscillations
分析了車載平臺的靜態誤差和動態誤差，計算車載平臺的各部分靜態、動態的剛度以及彎曲變形的影響。對振動的測試方法和測試設備進行了論述，提出對振動數據進行處理的方法，推導出車載平臺的振動模型，對各種振動進行了相應的簡化和耦合處理。 -
Based on the theories of bend loss and mode coupling, a model to analyze the characteristics of distributed spatial filtering of bend multimode fiber is given in this paper. then we made numerical simulation by the means of stepwise scan, dichotomy and the four orders runge - kutta. numerical simulation indicated that the distributed spatial filtering of the bend multimode fiber can improve the beam quality
本文從波動理論基礎出發，結合模式耦合理論和彎曲損耗理論，提出了一種用於分析彎曲多模光纖的空間濾波特性的理論模型，並運用逐步掃面法、二分法以及四階龍格-庫塔法對此模型進行了數值模擬。
