Abstract : a new concept of turning line of reduction parameters and its determination method is put forward in this paper for analyzing the isopleth diagram showing the relationship between reduction degree and reduction parameters in reduction of compressed scale lump containing carbon , and the method of optimal selection for reduction parameters is obtained 文摘:應用文章提出的還原參數界線概念及其確定方法對鐵鱗配焦壓塊還原過程中反映還原參數與還原指標關系的等高線圖進行分析，得出還原參數優化選擇的具體方法。

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 通過將影響污區分布的積污因素、鹽密指標、濕潤因素這三種因素綜合為等效鹽密,運用克里金法實現等效鹽密的插值,最終通過網格法繪制等值線圖實現了電網污區分布圖計算機自動繪制。

The hybrid algorithm raises the convergence rate of the conjugate gradient method and solves the problem for which the convergence rate of the steepest descent method get slower when the isopleth of goal function is oblong 這種混合優化算法結合了共扼梯度法和最速下降法產生搜索方向，既提高了共扼梯度算法的收斂速度，又解決了目標函數的等值線是扁長橢球時，最速下降法下降緩慢的問題，具有收斂速度快、收斂范圍大、適應面廣等特點。
