"solid earth tide" monograph was published TEXT SIZE:A A A
 

XU Hou-zhe’s monograph—— “solid earth tide” was published by Hubei science and technology press. The book was a financial assistance of the foundation of national science and technology learning compose publish. This book gave a detail theory introduction and experiment about solid earth tide home and abroad as well as the develop history and latest research progress in related areas.

Solid earth tide was induced by the attraction force change among the Sun, Moon, and Planet near the earth which leads to the periodic deformation of the inner and outer Earth. It is a key interdiscipline among astronomy, geodesy and geophysics.

Solid earth tide measurements and research were carried out at the end of 1950s in China. The researchers form WHIGG and Former Soviet Union developed the first gravity solid tide test in Lanzhou, Gansu province at that time. The institute of Geodesy and Geophysics established the gravity solid tide observe Station in Wuhan in 1980s. They promoted wide and deep cooperation among the institutes in Belgium, Germany and England. They developed the gravity tide profile across the main land of China, gravity solid tide profile in south-north coastal area, the permanent gravity tide observe station in Changcheng and Zhongshan station in South Pole,and Wuhan international gravity tide standard. There were also great progresses in theory research aspect, such as constructed earth tide model considering the sidewise heterogeneity of the mantle, constructed three-dimensional uniformity glacial isostatic adjustment model, ascertained the sympathetic vibration coefficient of natural oscillation and viscosity of the outer liquid core, explored the coupling between circline and sphericity concussion of the earth free oscillation and band splitting of the sphere solution.

In view of the outstanding contributions made by our researchers in solid earth tide ​​,XU Hou-zhe academician was elected the vice chairmen of international gravity committee(1983-1991) and chairman of international earth tide committee.
