摘要
按文献［１～４］，Ｌ＿ｐ与（ＦｅＯ＿ｎ）和Ｒ之间均有极值关系存在。本文得出从不同侧面反映的Ｌ＿ｐ极值关系式和曲线：（１）按ＣａＯ／ＳｉＯ＿２＝０～０．９，０．９１～１．９和＞１．９三个区段划分的，用１／Ｔ、ｌｇ｛（ＣａＯ）＋０．７（ｍｇＯ）｝、ｌｇ（ＴＦｅ）和ｌｇ（Ｐ＿２Ｏ＿５）表述的一次多项式；（２）按ＣａＯ／ＳｉＯ＿２＝０～０．０９，０．１～０．９，０．９１～１．４，１．４１～１．９和＞１．９五个区段划分的，用１／Ｔ，（∑ＦｅＯ）、（∑ＦｅＯ）￣２和ｌｇ（１＋ＳｉＯ＿２）表述的非齐次多项式；（３）按∑ＦｅＯ＝１３％～１５％，１６％～２０％和３０％～３５％三个区段描述的Ｌ＿ｐ－Ｒ极值曲线。并发现Ｌ＿ｐ与（∑ＦｅＯ）和Ｒ之间的极值关系存在一定规律。
It is found that extreme value relations exist between L_p and (FeO)_n as well as L_p and R according to experimental results in the literature￣[1～4].The L_p extreme relation equations and curves are:(1)When CaO/SiO_2=0～0.9,0.91～1.9 and >0.9, the L_p equations can be expressed as the first-order polynomial with 1/T, lg{(CaO)+0.7(MgO)},lg(TFe) and lg(P_2O_5)terms.(2)When CaO/SiO_2=0～0.09,0.1～0.9,0.91～1.4,1.41～1.9 and >1.9,the L_p equatiOns can be expressed as the non-homogenous polynomial with 1/T,(∑FeO),(∑FeO)￣2 and lg(1+SiO_2)terms.(3)The L_p-R extremal relation curves can be indicated when FeO=13～15%,16～20%, 30～35%.
