  1. With the mining of no. 1 ore body which is solwly inclined, large and thick at the west flank of xinqiao pyrite mine as the example, analytic comparision is made between flat - back cut and fill stoping and sublevel open stoping with one - time delayed filling. the suggestion on the optimization of the mining and the discussion on appropraite mining method and the technical parameters of mining technology for slowly inclined large and thick ore body are also made

    以新橋硫鐵礦礦體西翼緩傾斜厚大礦體的開采為實例,對生產中應用的水平分層充填采礦法和分段空場嗣後一次充填采礦法進行分析比較,提出采礦方法的優化建議,探討緩傾斜厚大礦體合適的采礦方法和采礦工藝技術參數。

  4. Based on this simulation method, the following novel designs are developed : 1, the two - stigma design, which can reduce the aberrations and improve the imaging of the grating ; 2, the flat - field design, which can omit the output waveguides and make an edg easier tc fabricate ; 3, the passband flattening design, which can relax the requirements on wavelength control for lasers and filters in a wdm system ; 4, the reduced back - reflection design, which guarantees very little reflection light back into the input channel and improves the feature of the return loss

    本論文以用於光通信中的平面集成蝕刻衍射光柵為研究對象,具體的分析了的它的工作原理和設計思想,並給出了設計中的經驗和方法。器件設計后需要進行性能計算和模擬以減小復雜的集成光器件製作試驗,本論文描述了計算蝕刻衍射光柵比較準確的模擬方法,其結果能夠很好的接近實際情況。基於這樣的模擬計算方法,本論文提出了改進蝕刻衍射光柵設計的幾種方法: 1
