In this paper,a new kind of approximation curves based on the trigonometric functions with shapes parameters which is named as BCSspline is developed (the spline is based on cosine and sine,and has the main superiority of Bspline),which retains the main superiority of Bspline method except only meeting C1 contiuity.
给出了一种以三角函数作为基函数的曲线拟合方法,称之为BCS样条 该样条具有B样条的主要优点,解决了传统方法不能描绘椭圆的问题,并且,该样条绘图效果良好,文中附有实例,充分说明此方法是进行几何造型的重要方法之
And the conclusion that the relation between the superconductivity temperature of MgB 2 and density of states satisfiys BCS theory was drawn,so the mechanism of MgB 2 is BCS mechanism.
根据密度泛函理论运用全势能线性muffin tin轨道 (FP LMTO :full potentiallinear muffin tin orbital)方法计算了不同压强下MgB2 晶格常数发生变化时的电子结构的变化情况 ,得出态密度的倒数与临界温度的自然对数成线性关系 ,符合BCS理论 ,从而进一步证实了MgB2 的超导机制为电—声子耦合BCS机
BCS theory is used to calculate the moments of inertia (Mol) of odd-A and even-even rare-earth nuclei.
