In this paper, we propose the definition of 6elements tensor impedance and briefly describe its some characteristics and determination techniques in the comparison with the former impedance tensor [Z].Furthermore, we explain the necessity of the proposed method and demonstrate its applicability by some field tests conducted in Democratic Peoples Republic of Korea %K MT法 %K 张量阻抗 %K 信噪比 %K 地球物理.< %K br> %K magnetotelluric exploration %K impedance tensor %K signal to noise ratio %K geophysics. %U http://www.earth-science.net/WebPage/Article.aspx?id=3985
