THE APPLIANCE RESEARCH OF 'AIR-RESISTANCE' ANDSTRUCTURE, MATERIAL AND CRAFTWORK IN THE THREETYPES OF DEEP-WELL ANODE UNDERGROUND BED ATDAQING AREA IN CHINA

摘要

According to the experience of long-term design, construction and research about three typesof deep-well anode cathodic protection object at Daqing area, the author first brought forward newanalysis and science discursion of 'air-resistance' and technique way to reduce and fall the'air-resistance' influence, and expatiated one new deep-well anode underground bed, which pushed newtechnology development.
