摘　　要：　作者研究表明[1～3]:混凝土电气加热蓄热冷却过程中温度(t)随时间(z)变化的客观规律可用吴震东方程精确描述和控制,文献[3,4]中各种不同形式的电极布置图可以满足混凝土冬季施工采用电极加热法的需求[4,5],本文在文献[3～5]的基础上对极间电阻(R)和扩散电功率(P)的计算公式中混凝土电阻系数ρ的主要影响因素,作深入的研究和分析。Author's researches show that objective law of temperature variation (t) varies with time (z)can be accurately described and controled by Wu Zhendong equation in the course of concrete electric heating and storage heat. In the paper all kinds of electrode arrangement diagrams can satisfy the requirements that concrete adopt electrode heating method in winter construction. On the basis of paper author deeply studies and analyses main factores on concrete's resistance coefficent ρ for resistance (R) between poles' distance and elechic power (P).
