  1. Two indexes was calculated to estimate the best bands union for color combination, one is optimum index factor ( oif, the sum of standard deviation divided by the sum of correlation coefficient. ), the other is the determinant of the co - variance matrix. it can be seen from the result that for color combination the original optimal bands were tm 4, 3, 7 and tm 4, 3, 5, the best mixed images were mnf1, br and ndvi

    以協方差矩陣行列式值和最佳指數值（組合波段標準差之和除以相關系數之和）為評價標準，得出對于tm原始波段而言，最佳的彩色合成組合是tm4 、 3 、 7和tm4 、 3 、 5 ；綜合幾種變換圖像的彩色合成的最佳組合是mnf1 、 br 、 ndvi 。
  2. 3, game theory analytics has been applied to improve mean - variance method of h. m. markowitz in fields of zero - sum game and non zero - sum game

    3 、運用博弈分析方法對馬克威茨的均值一方差法在零和博弈和非零和博弈的范疇內進行了改進。
  3. Document [ 14 ] proposes the modified clustering analysis : variance square sum clustering analysis, weighted variance square sum clustering analysis etc. but they have not explained the number of the division of economic zones, and only show how to divide the economic zones

    在文獻[ 14 ]中作者給出了改進的聚類分析的方法：方差平方和聚類分析、加權變量影響的方差平方和法聚類分析、預先確定組數的擬和聚類分析。
  4. Furthermore, we propose a parallel strategy to solve the multiple templates, multiple images " matching. then, we propose a skew estimation and rectification algorithm, in which wavelet transform is used ingeniously. we get horizontal edges and vertical edges simultaneously, and compute the sum of edge projections " variance in these two directions as no - skew measure

    本文提出了基於圖象規則邊緣結構的偏斜糾正演算法ser ，該演算法巧妙地應用了小波變換，同時得到水平和垂直兩方向上的邊緣分量，求取兩方向邊緣投影的方差之和作為無偏斜度量。
  5. Therefore, each sum of squares of deviations is the times of the consisitent and unbiased estimate of variance. so, if the division is reasonable, the sum of squares of deviations attained through the data to be grouped and the one attained through history data should be very close

    這樣，由於每個類內離差平方和為該數據所屬分佈的方差的相合且無偏的估計的倍數，故如果分類合理，則由待分數據得到的離差平方和應與由歷史數據得到的離差平方和相接近。
  6. The expressions of average value and variance of the phase difference and sum components are presented. we verified that under an appropriate condition the interference between the different transition processes makes counter balance, which induces the atom - field coupling system to be decoupled. the atomic population coherent trapping will take place

    模的相位保持隨機分佈，給出了光場兩個模相位差以及相位和的平均值與方差表達式，揭示了在適當的條件下，由於不同躍遷通道間的量于干涉效應，光場與原子退耦合，系統呈現原子布居數的相干俘獲現象。
