Examples
- With the three - dimensional ray - tracing program , the simulation of leo - gps occultation is given . the radio path of occultation observation is simulated , and then the excess phase delay is calculated . this work can be used for studying the effects of the neutral atmosphere and ionosphere on the occultation observations and evaluating the performance of the inversion techniques
本文介绍了无线电掩星技术的发展状况和基本原理,围绕无线电掩星技术及其应用研究展开诸多研究和探讨,主要工作内容如下: 1 、利用全球三维射线追踪程序,开展leo - gps掩星观测的模拟研究,以计算掩星观测时电波传播路径、计算大气引起的附加相位时延等。 - This technique can measure the profiles of meteorological fields of the neutral atmosphere and the electron densities of the ionosphere with high precision and high vertical resolutions . it can operate all - weather with long - term stabilities and global coverage . the global - distributed occultation data will have a huge promotion on the numerical weather prediction , climate and space weather researches
该技术可测量自地面到约800km高空的中性大气气象场和电离层电子密度剖面,具有全天候、长期稳定、高精度和高垂直分辨率等特点;该技术提供全球分布的资料,将对数值天气预报、气候研究和空间环境研究起极大的推动作用,在气象、空间、天文以及国防领域具有广泛的应用前景。 - The sample composition was analyzed by means of tg and x - ray diffraction . the following conclusions can be drawn from the experiments : given conditions , the sample powder that has the same xrd data as the standard fetioa can be gotten when use any method mentioned above ; the key in synthesis is to avoid the oxidation of fe2 + , so the whole process should performed under vacuum or neutral atmosphere , samples used by this study were prepared under nitrogen atmosphere ; the heat - treated time and temperature have some influence on the sample powder , results show that the proper time and temperature is 120 minutes and 1100 respectively
研究结果表明：在合适的反应条件下，用上述三种合成方法都能得到xrd数据与标准fetio _ 3物相基本吻合的粉体；合成反应需要克服的主要问题是防止体系中fe ~ ( 2 + )的氧化，因此，整个反应必须在真空或者非氧化性气体保护下进行，本研究需要的样品是在高纯从保护下合成的；煅烧的时间和温度对最终的产物也有一定的影响，研究发现：合理的煅烧时间和温度分别为120分钟和1100 。
