Collisonal quantum interference ( cqi ) was observed in the intramolecular rotational energy transfer in the experiment of the static cell, and the integral interference angles were measured. to observe more precise information, the experiment in the molecular beam should be taken, from which the differential interference angle can be obtained precisely. in this paper, the theoretical model of cqi is described in an atom - diatom system in the condition of the molecular beam, based on the first - born approximation of time dependent perturbation theory, taking into accounts the anisotropic lennard - jones interaction potentials. the method of observing and measuring correctly the differential interference angle is presented. the changing tendencies of the differential interference angle with the impact parameter, velocity, and et al. are discussed
分子內部轉動傳能的靜態池實驗觀察到了碰撞量子干涉效應（ cqi ） ，並且測得積分干涉角，為了獲得更加精確的分子內部轉動傳能的碰撞量子干涉效應信息，實驗就必須要採用分子束實驗進行.本文理論上採用各項異性相互作用勢，應用含時微擾理論的一級波恩近似，假想在分子束實驗的條件下，建立在原子-雙原子分子體系中碰撞量子干涉的理論模型.理論上推導出微分干涉角具體表達式，通過計算定性地討論了微分干涉角隨著碰撞參數、速率等的變化趨勢，同時初步探討了實驗的正確觀測途徑，得出了採用分子束進行實驗觀測的實驗方法，為進一步進行分子束實驗提供了理論基礎，對實驗的進行起到了一定的借鑒作用Adopting the actual county - grade database of land use firstly founded in china, combining with the comprehensive influential factors of land use change, using the correlative statistic software and the mathematic analytical methods ( principal component analysis, gray relating analysis, multivariate time series markov chain analysis, multivariate regression analysis, gm ( 1, 1 ) gray model, gray series gm ( 1, n ) model methods etc ), this paper analyses the dynamic change of land use and driving force in jiang ' an county qualitatively and quantitatively. the results indicate : 1 the land resource per capita and the area of single - land - use type in jiang ' an county are not prior to other places in yibing city or sichuan province. however, the terrain is dominant in choosing the way of land use
本文採用全國首批建立的「縣級土地利用現狀數據庫」的基礎數據，結合影響土地利用變化的經濟、社會、環境等綜合因素，採用相關分析軟體（ dps 、 spss ）和數學分析方法（主成分分析、灰色關聯度分析、多元回歸分析、多元時空序列馬爾柯夫鏈分析、 gm （ 1 ， 1 ）預測模型分析、灰色序列gm （ 1 ， n ）模型分析等方法） ，對江安縣土地利用變化及其驅動力進行定性、定量研究，研究結果表明： 1江安縣人均總的土地資源數量和單一土地利用類型的數量在宜賓或四川省區域內均無優勢；地形對土地利用方式的選擇起著主導作用；土地利用變化的總趨勢是：耕地、林地、交通用地和水域面積不斷減少，居民點及工礦用地和未利用地面積不斷增加；景觀多樣性指數呈現「 」趨勢。A homogenization - based method for predicting the viscoelastic property of multi - layered composite material is presented. by laplace transforming the governing equation of the viscoellastic problem of jointed rock, the dependent relation of the laplace transformation of the effective relaxation modulus of jointed rock on the joint distribution was derived by applying the homogenization method in laplace transformed domain. then, the effective relaxation modulus was obtained from the inverse transformation
