The two color systems hsv and hls are used for two reasons . firstly , they have advantages over the traditional method in using the ratio of the color components as separate images of the same scenes so that they can avoid linear correlation to color components 本文选用hsv和hls两种常用颜色模型计算彩色时变图像的光流场,实验结果表明该方法能得到相当精确的瞬时位置速度且适用于各种运动。
Deterioration series of populations were analyzed by the means of allozyme and rapd . the results showed that as the deterioration of grassland became heavier , genetic diversity would drop , but there was no distinct linear correlation between genetic diversity and deterioration degree 等位酶和rapd标记分析退化系列种群,其遗传多样性随退化程度加重有降低的趋势,但与退化程度无明显的线性相关。
To define the parameters of the model , correlation coefficient method was proposed based on goal programming principles with the hypothesis of linear correlation between maintenance requirement and maintenance technique and self - correlation among various maintenance techniques 为确定该模型中的各参数,在假定从维护需求到维护技术方法的配置关系及各种维护技术方法之间的自相关关系均为线性的条件下,基于目标规划原理,提出了相关系数法。
Based on those , the concept of chilling process was put forward according to the lowest biologic temperature of main tropic and south sub tropic crop and fruit in guangdong and the low temperature ( environment temperature 5 . 0 ) which is harmful to those crop and fruit . with the lowest air temperature ( the daily lowest air temperature ) x1 , the lasting days of low temperature x2 and an integrative physical element - - negative accumulated temperature x3 in which the effect of the intense and lasting days of low temperature were considered , the correlation coefficient of those indexes were calculated and analyzed , and the results showed that there are apparent linear correlations among them 在此基础上,以广东主要热带南亚热带作物的生物学下限温度为依据,从这些作物受寒害的起点温度(环境温度5 . 0 )出发,提出了寒害过程的概念,并用寒害过程低温的强度(逐日最低气温) x _ 1 、低温的持续时间(天数) x _ 2及考虑了低温的强度和持续时间综合作用的物理量负积温x _ 3这3个指标来描述寒害的强度,研究了广东历年冬季寒害的变化,分析了这3个指标间的相关系数,结果表明它们之间互相存在显著的相关关系。
There was double - logarithmic linear correlation significantly between specific weight metabolic rate and temperature in each of weight groups . temperature exponent ( b ) in the regression equation increased with weight increasing . the covariance analysis showed that the difference between the every two temperature exponents in the equations was significant ( 2 )特定体重代谢率随温度的上升而上升,各体重组的代谢率与温度之间均呈显著的双对数直线相关;温度指数( b )随体重的增加呈现上升的趋势,协方差分析表明,回归方程的温度指数( b )间差异显著。
The space - time distribution of chinese semi - ari d region surface water is n ' t even , the differences in a year are obvious ; the differences of underground water between years are not so obvious as surface water , but it still has a decreasing tendency , especially in shanxi and sha ' anxi provinces . there is a significant linear correlation between the precipitation and water resources in semi - arid region , the dynamic regularity of water resources is basically same as the dynamic regularity of precipitation 半干旱地区地表水资源时空分布不均匀,年内分配差别大,地下水资源年际间变化率不大,但总体有减少的趋势,尤以陕西和山西突出。半干旱地区降水量与水资源量线性相关显著,降水量的变化规律基本上与水资源量的变化规律吻合。
A new type of pressure coefficient cp is defined to lead to a linear correlation with radial locations , which will lead to a curve correlation with radial locations with conventional definition of cp . the correlations of cm , nuave and cp with rotational reynolds number have been got through the computation with rotational reynolds number from zero to 1 . 0 108 给出了扭矩系数cm 、平均换热系数nu _ ( ave )随旋转雷诺数变化的关系式,发现它们与没有预旋时是完全不同的,当re _ = 0时, cm 、 nu _ ( ave )不为零,而具有一个初值。
The results show that , in most samples there are some linear correlation between poisson ' s ratio anisotropy and p - wave velocity anisotropy ; while in some samples there are no significant correlation between them ; some samples even show totally opposite changes in poisson ' s ratio anisotropy and p - wave velocity anisotropy 结果表明,在大部分样品中泊松比各向异性与纵波速度各向异性有一定的相关性,但在有的样品中泊松比各向异性与纵波速度各向异性没有明显的关系,甚至表现出完全相反的变化规律。
