quadrature formula

If the coefficients 1, then we call a positive quadrature formula.

如果系数1, 然后我们称之为积极的求积公式.

However, in calculating the range nominal resolution of rectangular pulse signals using conventional definition formula, quadrature operation for range ambiguity function or infinite integration for "SIN" function is required.

然而，对矩形脉冲信号来说，按常规定义式计算距离名义分辨力，需要距离模糊函数的积分运算或对正弦函数进行无穷积分，这些积分运算往往较为复杂或为不定值；

There are no conductions about the obvious form and the error equation of Romberg's quadrature formula in present literatures.

现有文献并没有介绍Romberg求积公式的显示形式，没有误差等式。

In this paper, the obvious form of Romberg's quadrature formula and the error equation is presented.

在这里将给出Romberg求积公式的显示形式和误差等式。

Then, using the second-order central difference to discretize the time derivative of the displacement, and applying the quadrature formula to the mass matrix, a fully discrete lumped mass Morley element method is developed for the same problem.

然后利用中心差分格式离散时间方向的二阶导数，再利用适当的求积公式得到薄板弯曲问题的集中质量Morley元全离散格式。
