祖国在一日千里万里奔腾的发展中,年轻的物探事业在党的亲切关怀与培养下,也随社会主义发展的需要而日益的成长和壮大着,这给我国勘探事业开辟了一条新的科学道路。但这仍不能满足新形势的发展速度要求。为了在保证质量的基础上,提高工作效率,我们在地面电测工作中进行了电位差和电流同时 In the development of the motherland in the thousands and thousands of miles a day, the young geophysical exploration career has grown and expanded with the development of socialism with the cordial care and cultivation of the party. This opens up a new scientific path for the exploration of our country. However, this still can not meet the requirements of the speed of development in the new situation. In order to ensure the quality of the basis to improve work efficiency, we conducted in the ground electrical potential difference and current at the same time
