riemann surface

基本解释

It is very convenient to calculate the object volume to use Riemann sum after obtained the object surface region equation.
在已知空间物体表面区域方程的前提下，利用黎曼和可以方便地求出被测物体的体积。
The linear model is exploited to approximate the reflecting continuous spectrum of the object surface and numerical computation is conducted via Gaussian quadrature (GQ) and Riemann summation (RS).
首先用线性模型来逼近物体表面的反射光谱连续函数。然后用高斯积分法、黎曼求和法进行了数值计算。
