地球物理学是一门牵涉很广的科学,它的研究对象遍及地球内部、地球本身以及在地球大气中所发生的一切,而很多地球物理现象的因素还来自空气层以外,特别是来自太阳和月亮。从今年到明年,太阳活动比较厉害。因此世界各国的科学家们决定将今年7月1日到明年年底这段时间作为国际地球物理年,对很多地球物理现象作较大规模的观测和研究。现在就特地向大家介绍科学普及出版社出版的几本有关地球物理的小册子。“地磁知识”(徐静明著,1957年6月出版,定价0.11元)是一本介绍有关地磁的一般知识,地球的磁场和它的变化等的小册子。地磁这门科学在国民经济中有着重要
Geophysics is a science that involves a wide range of subjects. Its research objects are all over the earth, the earth itself, and everything that happens in the earth’s atmosphere. Many geophysical phenomena also come from outside the air layer, especially from the sun and moon. From this year to next year, solar activity is more severe. Scientists from all over the world have therefore decided to use the period from July 1st to the end of next year as the International Geophysical Year to conduct large-scale observations and research on many geophysical phenomena. We will now personally introduce several brochures on geophysics published by Science Popularization Press. “Magnetic knowledge” (Xu Jingming, published in June 1957, priced at 0.11 yuan) is a booklet introducing general knowledge of geomagnetism, the magnetic field of the earth and its changes. The science of geomagnetism is important in the national economy
