采用灰化法处理样品，HNO3溶解灰化残渣，用火焰原子吸收光谱法测定了射干、白头翁、山豆根、鱼腥草、连翘、大青叶、车前草、野菊花、金银花、莲子芯、蒲公英、板兰根等20种中草药中的Ca，Mg，Mn，Cu，Fe，Zn，Cd，Pb，Co，Ni和Cr共11种微量元素。

First, a special normal transversal at the initial point is constructed and a second-order Taylor's algorithm is used to trace the projections along the aforementioned normal transversal. A curvature based method for controlling iteration step is further proposed by projecting the given point onto the curvature circle of the normal transversal at the initial point. Finally gradient based method for correcting iteration errors is put forward.

首先构造初始点处的一条特殊的法截线，并给出沿着该法截线追踪投影点的二阶泰勒迭代方法；然后将给定点向初始点处的法截线的曲率圆作投影，提出基于曲率的步长控制策略，在此基础上给出了基于梯度的迭代误差矫正方法。
