Then set out from our domestic reality, it analyzes the characteristics of tax after the reform based on the data from 1994 to 2004. with the method of cross sectional analyses, it adopts the concept of the marginal tax rate to make empiristic analyses about china ’ s provincial tax growth and economic growth since 1995 to 2004
然後，從我國的實際情況出發，以1994 ? ? 2004年為例，分析了稅制改革后我國稅收收入所呈現的特徵，並採用了邊際稅率的概念，通過橫截面回歸的分析方法，對我國1995 ? ? 2004年各地區的稅收收入與經濟增長進行實證分析。 -
In this article, a comparison between basic genetic algorithms and optimal elitist model niche genetic algorithms is made and it illustrates that the optimization has greatly optimized the previous sectional solutions and has speeded up the algorithm convergence and the rate of convergence
摘要探討了基於穩態復制策略的二進制小生境遺傳演算法，並把其應用於復雜函數優化問題中，通過與基於最優保存策略的基本遺傳演算法進行比較，說明改進演算法可以極大克服遺傳演算法未成熟收斂問題以及極易陷入局部解問題，提高了演算法收斂性能和收斂速度。 -
High quality znsxse1 - x thin film grown at the optimized temperature had the smoothest surface with lowest rms value of 1. 2 nm and tem cross - sectional micrograph showing a well defined columnar structure. the dependence of substrate temperature, deposition rate and alloy composition to the structure of the film was discussed in the thesis. the developed theory named " quasi - structure area mode " can successfully explain the film growth mechanism of polycrystalline znsxse1 - x thin films deposited on ito substrate by mbe
研究了採用mbe系統沉積zns _ xse _ （ 1 - x ）多晶薄膜的生長機理，分析了襯底溫度、沉積速率及薄膜組分對薄膜微結構的影響，提出的「類結構區域模型」可以較完整地解釋ito襯底上zns _ xse _ （ 1 - x ）多晶薄膜生長的機理。
