这种混合优化算法结合了共扼梯度法和最速下降法产生搜索方向，既提高了共扼梯度算法的收敛速度，又解决了目标函数的等值线是扁长椭球时，最速下降法下降缓慢的问题，具有收敛速度快、收敛范围大、适应面广等特点。 - The paper applies sdm in drawing the map of pollution areas . by synthesizing contaminated factor , saturated esdd and damp factor in pollution areas , the equal saturated esdd is presented . the isopleth map for equal saturated esdd is drawn by grid method based on kriging regression , and the isopleth map is regarded as the map of pollution areas
通过将影响污区分布的积污因素、盐密指标、湿润因素这三种因素综合为等效盐密,运用克里金法实现等效盐密的插值,最终通过网格法绘制等值线图实现了电网污区分布图计算机自动绘制。
