...A direct current is passed from one pair of electrodes (current electrodes AB) to the ground, and the resulting electric field is observed with another pair of electrodes (potential electrodes MN) (Figure 1). There are many types of electrode arrangements, but the most common are the Schlumberger method and the Wenner method, which are deployed along a single measurement line. In both cases, the apparent resistivity ρ a is calculated from the applied current I , the observed potential difference V , and the distance between the electrodes. ... *Some of the terminology that refers to the "Wenner process" is listed below.

…1対の電極(電流極AB)から大地に直流電流を流し,その結果として形成される電場を他の1対の電極(電位極MN)で観測する(図1)。電極配置には多くの種類があるが,1本の測線上に展開するシュランベルジャー法とウェンナー法が最も普及している。ともに,流した電流Iと観測された電位差Vおよび電極間の距離から見掛比抵抗ρaを計算する。… ※「ウェンナー法」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
