根據松遼盆地深層天然氣區帶地質評價參數取值標準，進行區帶地質評價，並通過與刻度區類比，得出深層天然氣資源量為11161 . 44 10 ^ 8立方公尺，主要分佈在徐家圍子、廟臺子、長嶺、鶯山、古龍等區帶中。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。The conclusions have been deduced from the detailed analysis of a set of experimental results as below : 1 ) the formula of tangent young ' s modulus et has been established during the unloading process ; 2 ) the shearing features of the samples are similar to undrained test even though there are draining paths so the possion ratio of the sample is about 0. 5 ; 3 ) unloading paths have little effects on the shearing strength parameters
通過對試驗結果的分析得到： 1 ）任一時刻土體的切線彈性模量公式； 2 ）卸載情況下盡管存在排水通道，但試樣仍基本上表現為不排水的性狀，按廣義虎克定律得到的泊松比在0 . 5附近； 3 ）卸荷應力路徑對土體的強度參數影響不大。Because p - si is of more special characteristics, comparing to a - si and c - si, firstly, i set forth electrical features of p - si film and acknowledge profoundly electrical mechanism of p - si film. then three parameters of laser annealing, including laser frequency -, accepted - pulse - times and laser power density are studied how to influence crystallization of p - si
因為多晶硅和非晶硅及晶體硅相比具有更獨特的特點，所以我們先闡述了多晶硅薄膜的電學特點，對多晶硅的導電機理有了深刻的了解；然後研究了激光頻率、受光次數和激光功率密度三個參數對晶化多晶硅的影響。Through the analysis, it is shown that : 1, while fabricating the grating, the principle of selecting the parameters is : the period should be as large as possible, the etching depth should be small and filling factor should approach to 0. 25. 2, if selecting the parameter combine the selecting principle and the requirement of concrete application, the space of selecting the parameter should be larger than before. 3, while the period to. 4a, the surface profile has no effect on the reflectivity
通過分析發現： 1 、在製作有一定特性的光柵時，光柵參數的選擇原則為：周期的取值應盡量的大，刻蝕深度的取值應盡量的小，占空比的取值應盡量靠近f = 0 . 25 ； 2 、以參數的選擇原則結合製作的具體應用要求宋選擇光柵的參數，則各個參數的優化空間更大； 3 、當光柵的周期t 0 . 4時，表面面形對反射率沒有影響； 4 、運用臨界周期點隨折射率的變化規律，可以避免由於選擇光柵周期過大而出現一級衍射，從而導致製作失敗。The oxidizing parameters of the anodization in the following experiments were preferred on the basis of measuring the dependence of pl properties ( peak position, and max intensity, etc. ) on anodization conditions, such as the anodizing current density, the time of the anodization, the concentration of the solution ( mainly of hf ), and on the doping level of the substrate
刻蝕時間、刻蝕液配比及襯底電阻率對pl發光強度、峰值波長等性質的影響。在此基礎上優化出制備多孔硅的具體參數。對不摻sb與摻sb的snci 。分享友人
