Research on Planar Cubic PH Spline and the Inflection Points and Singularities on F-curve 三次插值PH样条与F-曲线拐点和奇点的研究
Two methods were used to solve the convection-diffusion equation which appropriate to straight single-tube Flow Injection Analysis ( FIA) system without chemical reaction, and the concentration distribution of the slug-injected sample after dispersing in the tube was obtained. F-Curve was thereby obtained. 用两种方法求解适合于单一平直管道且无化学反应的流动注射分析(FIA)体系的对流-扩散方程,得到了描述塞状进样在管道中分散后的浓度分布公式,从而得到F曲线。
