杨氏双缝干涉
两相干光源到接收屏上P点距离r1=(D2+(y-a/2)2)1/2, r2=(D2+(y+a/2)2)1/2,
满足相干条件的光波叠加后,对于观察屏上某一确定点,即r1、r2确定后,叠加后的光强为 式中λ为光波的波长, 、 ,令相位差φ=2π(r2-r1)/λ,
最后可得公式如下:
,
最后光强I=4I0cos2(Φ/2)。
观察相干光叠加后光强的分布.
(Young' s double slit interference two coherent light source to the point P on the receiving screen distance r1 = (D2+ (YA/2) 2) 1/2, r2 = (D2+ (y+a/2) 2) 1/2, meet coherent conditions lightwave after superposition, for a determined point on the viewing screen, i.e. R1, R2 is determined, the superimposed light intensity where λ is the wavelength of light, make the phase difference φ = 2π (R2-R1)/λ, final can be obtained using the following formula: Finally, the light intensity I = 4I0cos2 (φ/2). Observed coherent superposition of light intensity distribution.)

spline3
三次样条插值函数边界条件由实际问题对三次样条插值在端点的状态要求给出。以第 1 边界条件为例,
用节点处二阶导数表示三次样条插值函数,用追赶法求解相关方程组。通过 Matlab 编制三次样条函数的通用程序,
可直接显示各区间段三次样条函数体表达式,计算出已给点插值并显示各区间分段曲线图。(Cubic spline interpolation function boundary condition for the practical problems cubic spline interpolation required to give the state the endpoint. In the first boundary condition, for example, with a node represents the second derivative of the cubic spline interpolation function for solving the relevant equations with catching method. General Procedure prepared by the cubic spline function Matlab, can directly display each range segment cubic spline function body expression, to the point of interpolation is calculated and displayed for each interval segment curve.)
