首项系数 meaning in English

leading coefficient

In this paper , we discusse the stability of perturtation of m - p inverses of closed operator function and then the stability of least square solution of elliptic partial differential equations of second order with unbounded coefficients
本文讨论了闭算子的m - p广义逆的扰动,并由此讨论首项系数本质无界的二阶散度型椭圆型微分方程的最小范数极小二乘解的稳定性
