| 摘 要： | In Order to study the Global Characteristics of Solar-terrestrial System in the 22th Solar Cycle, our Institute has built up a few geomagnetic observatories recently years at Mohe, Beijing (Ming Toms), Sanya (Hainan Insland) in the torritorg of China. These stations together with some old stations close to 120° E meridian and form the East Asia Meridian Chain of Geomagnetic Observatories. In the meantime we were set up also a observatory of the Chinese Great Wall Station in Antarctica. According to theather character of different area we designed and built the house with different structural style.The magnetic recording house is the under ground in Mohe, the semi-under ground in Beijing, the ground in sanya of China.The recording and the absolute houses are all built on stilts in the Chinese Great Wall Station of Antarctica. All buildins are made of non magnetic materials, Such as limestone, sun-dried mud brick, wood, copper and Aluminum etc.Therefore there are not affects of the magnetic materiat arou
