并址技术是指在同一测站位置同时利用GPS、SLR、VLBI等不同空间定位技术进行观测的方法.本文利用上海台站并址的GPS、SLR、VLBI技术观测近10年的数据对台站所处地壳垂直运动进行监测,发现不同技术手段对相同地理位置地壳运动监测结果存在相似性,同时也有一定程度的差异,针对这种现象本文进行了分析与探讨.
Datum of velocity was unified with ITRF2008 solutions, North American CORS network, CMONOC and European CORS network.The Euler vectors of the main fourteen plate’ s definite by IERS were calculated and refined with the unified velocity.The station selected methods by least square was determined.According with the experiment we can found that the LS method was good at improving the efficiency and security of selecting stations.The status of plate motion could be incarnated greatly with more steady sta-tions and equably distributing.
以陆态网络CORS站中的武汉站为切入点,分别采用ARIMA模型和傅里叶拟合模型对武汉站10 a左右的观测时间序列进行分析拟合。实验表明,ARIMA模型和傅里叶拟合模型都能较好地拟合武汉站测站时间序列,但从细节来讲,ARIMA模型理论严密,拟合效果稳定;而傅里叶拟合模型更有利于直观分析时间序列中的各种周期频谱特性。
以陆态网一期工程27个连续运行基准站为研究对象,通过对其约十二年的测站观测时间序列分析发现绝大部分测站垂直方向都包含有明显的周年位移规律,综合各种地球物理资料及相关部分参考文献,本文对该规律的产生机制进行了分析讨论。
The preparation method of(NH4)2SO4·FeSO4·6H2O has been carried on the analysis and the improvement in thechemical experiment teaching material.After the improvement,there are lots of merits—the pure color,the high production rate,the high purity,the quick speed and so on.
