1.意义 高斯曲线 ,又叫做gaussian curve,是正态分布中的一条标准曲线。具有以下特征: 1.1 正态曲线在横轴上方均数处最高; 1.2 正在分布以均数为中心,左右对称; 1.3 正态分布有两个参数,即均数和标准差;标准正态分布用N(0,1)表示; 1.4 正态曲线下的面积分布有一定的规律。 在分析仪器的测量中,有许多具有明...
精华评论 SHY31 很简单 你首先用CHEMDRAW例子里面直接有的~~各种的C62,C60等等 然后转换到Gaussianview里面就可以进行计算了 jghe 楼上的方法也许挺好的,我推荐一个网址,各种富勒烯结构都有 http://www.cochem2.tutkie.tut.ac.jp/Fuller/fsl/fsl.html,...

Gaussian distribution 在各类理工科,甚至是社会科学文献中,时常会看到Gaussian distribution这种说法,有时甚至直接说Gaussian。Gauss指得就是“数学王子”高斯,而“高斯的”distribution,其实就是我们常说的“正态分布”或者“钟形分布”(bell curve)。(但是...

SCRF defaults to the symmetric form of IEFPCM [Lipparini10] (not present in Gaussian 09) rather than the non-symmetric version. Physical constants use the 2010 values rather than the 2006 values in Gaussian 09. The first two items were changed to ensure accuracy in several new calculation typ...
