密度泛函理论?答:密度泛函理论的含义从其英文“Density functional theory”更能直观的反映出来,它应用“电子密度泛函数”来处理多体问题。而泛函数通常指一种定义域为函数,而值域为实数的函数,换句话说,是一种函数组成的向量空间到实数的一个映射[3]。泛函数常用来寻找某个能量泛函的最小系统状态,这为密度泛函理论...

Lattice density functional theory has several advantages over more complicated free volume techniques such as Perturbation theory and the statistical associating fluid theory, including mathematical simplicity and ease of incorporating complex boundary conditions. Although this approach is known to give only q...

So Wikipedia is saying the average density of Sydney is roughly about 3 people per soccer field. You don’t need to have visited Sydney to know that is complete nonsense (don’t get me wrong, I love Wikipedia, but it really need to use a better measure for city density!). The major...
