4　地球物理探矿技术与装备的新发展近年来正当世界矿产地质勘查活动由于勘查经费的削减而处于低迷衰退的困境时,地球物理探矿行业却在艰难的时势下有很大的发展。这一方面是由于在剧烈的市场竞争中迫使各国物探企业去努力研制开发新的技术和装备,以技术优势去争取更大的市场份 4 NEW DEVELOPMENT OF GEOPHYSICAL EXPLORATION TECHNIQUES AND EQUIPMENT In recent years, geophysical prospecting industry developed rapidly under difficult times in the recent period when the world mineral geological prospecting activities were in a downturn due to the reduction of exploration funds. This is partly due to the fact that in the fierce market competition, geophysical exploration companies in all countries are forced to work hard to develop new technologies and equipment and strive for greater market share with technological advantages
