The electronic density of states (DOS) of the system as well as low temperature thermodynamic quantities are obtained under the saddle pointapproximation.
在鞍点近似下，求得了系统的电子态密度和一些低温热力学量。
2
But, if you fix a point, then we have linear approximation.
但是，如果你固定了一个点，就能得到线性近似。
3
Sets the pixel at the specified point to the closest approximation of the specified color.
