针对由于大地高所引起的地面区域实际球面面积与其在参考椭球面上的面积不一致的问题,采用椭球膨胀法对以地面作为投影面计算地面区域实际球面面积进行研究.得到以地面区域的平均大地高为参数将其在参考椭球面上的面积改化为地面实际球面面积的实用方法.研究结果表明:该方法计算简便、精度高,面积修正的相对误差达百万分之一量级.
Firstly,the Earths gravitational field from the past Challenging Minisatellite Payload(CHAMP) mission is determined using the energy conservation principle,the combined error model of the cumulative g
According to the space-geodetic data recorded at globally distributed stations over solid land spanning a period of more than 20-years under the International Terrestrial Reference Frame 2008,our prev
The Gravity Recovery and Climate Experiment(GRACE) mission can significantly improve our knowledge of the temporal variability of the Earths gravity field.We obtained monthly gravity field solutions b
【目的】绿针假单胞菌GP72是一株可生产吩嗪类抗生素吩嗪-1-羧酸(PCA)及2-羟基吩嗪(2-OH-PHZ)的生防假单胞菌。Rpe A/Rpe B双元调控系统是其双元调控系统中的一组,本文旨在研究这一系统中的应答调控子(RR)Rpe B对于PCA及2-OH-PHZ的生物合成影响。【方法】通过生物信息学分析获得了rpe A/rpe B双元调控系统的序列,并从GP72中扩增出rpe B基因,通过同源

针对某110kV变电站10kV备自投装置频繁发出异常告警信号,分析了缺陷产生的原因,探讨了综合自动化变电站GPS时钟同步系统对二次设备的授时原理、授时方式、授时结构和过程,并通过分析影响备自投等二次设备时间同步的因素,对该缺陷进行了消缺整改。
针对实际车载组合导航系统测量中不确定噪声的问题,提出一种基于不确定融合估计的GPS/INS组合导航滤波算法,建立了导航系统的状态方程和观测方程;通过多信源不确定融合估计,得到多传感器的等效测量值以及误差方差阵;对系统方程进行滤波处理,得到车辆的准确位置.车载系统的实测数据表明,不确定噪声下的融合估计结果优于独立白噪声假设下的融合估计,并验证了所提出算法的有效性和实用性.
