Based on these conditions,the calculation results of permeability coefficient indicate that during the course of the main compression settlement,the change law of landfill permeability coefficient index is approximately agreed with nature exponential law,expect for the condition of landfill body without pressure.
结果表明,4种压力状况下垃圾填埋体试验测定分析符合达西定律,其COD变化处于产酸阶段,对渗透性能的影响可以不予考虑;在此基础上,对垃圾渗透系数计算表明,处于主压缩沉降阶段内,除没有施加压力状况下垃圾填埋体渗透性能变化规律与其他试验表现不尽相同外,其他垃圾填埋体渗透系数变化大致符合自然指数规律,而4种压力状态下的垃圾填埋体渗透系数数值均在10-4。
By using the so-called"natural level functions",we extend the well-known damped Newton method to solve ill-conditioned systems of nonlinear equations.
利用自然水平函数,将众所周知的阻尼牛顿法进行推广,用于求解病态非线性方程组。
In this paper,using the data acquired from Mid Indian rainfall in 1951 to 1985,the four typical years of the stronger monsoon and the six typical years of the weaker monsoon were chosen,in which 500hPa height fields were analyzed by the anomaly synthetic analysis and CEOF(complex empirical orthogonal function) respectively.
本文应用１９５１—１９８５年印度夏季风资料，选取强季风年４年和弱季风年６年，分别对北半球５００ｈＰａ高度场进行距平合成分析和复自然正交函数（ＣＥＯＦ）分析。
Using natural spline functions with multiple knots, we discuss the extended Sard approximation of Linear functional.
本文利用具有重结点的自然样条函数,讨论了线性泛函Ff=sum from i=0 to n-1[integral from a to b a_i(x)D~i f(x)dx+sum from j=0 to L~1 b_(ij)D~i f(x_(ij))]的广义Sard逼近问题。
