bromine(-containing) substance

In this paper,a new kind of approximation curves based on the trigonometric functions with shapes parameters which is named as BCSspline is developed (the spline is based on cosine and sine,and has the main superiority of Bspline),which retains the main superiority of Bspline method except only meeting C1 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.

用BCS理论计算了稀土区偶偶核和奇A核的转动惯量。
