重力場理論及其應用
 
Theory and application for gravity field

  地球重力場是地球內部和近地空間物質密度分布和空間位置的綜合反映,是研究地球內部結構及其運動的重要物理量。重力場所包含的信息十分豐富且重力資料具有范圍廣、精度和分辨率高、觀測成本相對較低廉等優勢也就決定了重力場具有廣泛的應用。目前重力場已經廣泛應用于地球內部結構研究、礦產資源勘探、地震活動性研究、水資源分布變化以及國防軍事等領域之中,為人類帶來了巨大的社會和經濟效益。同時由于重力場的復雜性也引出了許多期待解決的科學問題。針對地球內部結構及地球動力學前沿領域,以及國防建設、資源開發利用和災害監測的迫切需求,重點研究全球和中國大陸重力場時空變化及其規律與機制;發展我國自主重力衛星觀測系統;研制適合導彈部隊戰場需求的小型絕對重力儀;研究遠程武器發射場的重力保障技術和潛艇水下無源重力匹配導航技術;開展大地構造、地殼結構以及深部隱伏礦產資源勘探。主要研究內容:

從事重力場理論、技術與方法及在國防和國民經濟中的應用。包括地球重力場和大地水準面的確定、衛星測高、島礁重力測量、重力場時空變化,絕對重力測量、重力輔助導航系統、重力/慣導組合技術的理論方法和技術、重力場的分離與反演及其在地球內部結構研究和礦產資源勘探中的應用等。

The earth's gravity field, an important physical quantity to research the earth's inner structure and movement, is the integrated reflection of inner and upper matter's density distribution and spatial position of the earth. Gravity data have the advantage of wide range, high precision and resolution and relative cheap observation cost, so that the gravity field which contains abundant information has broad applications. Presently, the gravity field which has widely applied in research of inner structure of the earth and seismic activity, mine resource exploration, change of water resource distribution, national defense and military field, brings enormous social and economic benefits for human. At the same time, it brings many scientific problems to resolved because of the complexity the of the gravity field. We focus on the space-time changes, laws and mechanisms of the gravity field of china and globe, aiming at frontier fields of geodynamics and inner structure of the earth, and urgent needs of national defense and construction, resource exploration, and disasters monitor. Developing national independent gravity satellite observation systems and mini-instruments for absolute gravity measurements that adapt to battlefield needs for missile units. Researching gravity security technology of launch site for long-range weapons and underwater initiative gravity matching navigation techniques of nuke. Developing geotectology, crustal structure, and deep hidden mine resource exploration. Primary research content as:

Gravity field theory, technique and method, and application in national defense and economy. Including gravity field and geoid confirmation, satellite altimetry, island reef gravity survey, space-time variation of gravity field, absolute gravity measurements, gravity aided inertial navigation system, theory and technology of gravity/inertial navigation integrated technology, separation and inversion of gravity field and its application in the study on interior structure of the earth and mine resource exploration.
