The crust in western China is in the state of isostasy.
中国西部地壳处于地壳均衡状态。
The conception of crustal isostasy produces a great effect to the geo-scientific research; especially take an important role in the studies of Geodesy and Geodynamics.
地壳均衡的概念对地学的研究有着极大的影响，特别是在大地测量学和地球动力学中发挥了重要作用。
Base on theory of lithosphere elastic flexure isostatic compensation, the spheric harmonic series expressions of topography-isostasy compensation gravity and geoid are established.
