石油化工腐蚀与防护 1984年第3期 57-75页

作者：李根照洛阳设计研究院设备所

在利用电化学测定金属在电解质体系腐蚀速度的方法中常用的有极化曲线外延法和极化阴力法。极化曲线外延法是将阳极和阴极极化曲线上的塔菲尔线性段外延到腐蚀电位测定腐蚀速度的方法,由于很大的极化严重

Let K be a skew field and Z be its *** multiplicative groups of non-zero ele-ments of K and Z are denoted by K*and Z**** by GL2（K） the groupof all 2×2 matrices over K and by PGL2（K） the factor group of GL2（K） modulo its ce-nter consisting of all elements of the form γI,where γ∈Z*and I is the 2×2 *** K is commutative or is of characteristic≠0 the automorphisms of PGL2（K）are already *** the present paper,we'll determine the automorphisms of PGL2（K）

A global model of the atmospheric conductivity in the region below 200 km is calculatedusing the latest measured data and chemical model of the middle atmosphere. The influencesof various sources of ionization, i.e., cosmic rays, solar EUV radiation and X-ray radiation,are analzed. The numerical results show that the relative sensitivity of conductivity to thewhole ionization sources is about 50% for the most part of altitude. Using the semi-empiri-cal formulas for the cosmic-ray ion-pair production rate, up to more than 50% relative modu-lation of the atmospheric conductivity by the 11 year solar cycle is obtained near the polarregion and below 70 km. The calculated global resistance of the whole atmosphere is 182Ω.The comparison of the calculation with observation and other semi-empirical model shows afairly good agreement.
