Dichotomy Methods Successive dichotomy uses a totally different approach to the problem of indexing. The constants A to F in the equation Q = A h2 + B k2 + C l2 + D kl + E hl + F hk are assigned minimum and maximum values so that for a gi

有限单元法求解二阶偏微分方程，使用的方法是加权余量法，比一阶方程更加可靠-Finite element method for second order partial differential equations, a method using a weighted residual method is more reliable than the first-order equation
