Examples
- Relationship between earth gravity field and sst by numerical simulation
地球外部引力场引起卫星间距离变化的数值模拟研究 - In this area , the development of early rockets is chronicled from the earliest conceptions of propulsion to the invention of liquid fuel rockets capable of escaping the earths gravity
这个展览区依次展示火箭早期发展的情况，概述火箭由最早的推进器发展至能够摆脱地心吸力的液体燃料火箭。 - The characteristics of the normal equation created in recovering the earth gravity model ( egm ) by least - squares ( ls ) adjustment from the in - situ disturbing potential has been discussed in detail
摘要讨论了在基于能量法确定地球重力场模型的过程中，利用最小二乘方法由沿轨扰动位数据解算位系数时法方程的特性，在该问题中，法方程只与卫星轨道有关。 - Airborne gravimetry is applied to rapidly get extensively and precisely well - distributed information of the earth gravity field in order to meet the needs of geodesy , geophysics , oceanography , exploration , space - science and the other fields . airborne gravimetry includes scalar airborne gravimetry and vector airborne gravimetry . scalar airborne gravimetry is used to get the value of the gravity acceleration , and vector airborne gravimetry can get not only the value but also the direction of the gravity acceleration
它可以快速获取精度良好、分布均匀、大面积的地球重力场信息，而且能够在一些难以实施地面重力测量的特殊地区如沙漠、冰川、沼泽、原始森林等进行作业，从而能够满足大地测量学、地球物理学、海洋学及资源勘探等学科和领域对地球重力场信息的需求，并能为空间科学提供强有力的地球重力场保障。
