摘　　要：研究了在土壤模拟溶液中,外加杂散电流的强度和方向对由Mg合金牺牲阳极和涂覆层组成的埋地钢质管线体系的干扰作用及外加杂散电流强度及方向之间的关系。The paper reported that in the earth simulated solution, there is impressed stray current intensity and direction disturbance function on the buried steel pipeline system, which made of Mg allog sacrificial anode and coating layer. The relationship between the empressed stray current intensity and direction were also given.
