Explicit integration of integrals of the type basic to comparison of observed and predicted values of the earth's mean total magnetic field reveals an error in the numerical integration recently employed by Raymond H. Wilson, Jr., in making such a comparison for the special case of Vanguard I. Correction of this error destroys the satisfactory agreement he found between the value implied by rotational damping and the theoretical value. Continued numerical improvement of all parts of my previous report, based on later accumulation and rediscussion of data, has revealed several small random adjustments, including the arithmetical correction discussed by LaPaz. The consequent result remains a satisfactory agreement of the groundobserved geomagnetic dipole field with that deduced from rotational retardation of the Vanguard I satellite. 相似文献

为了使养殖场因有害性赤潮而受到的损失最小,最好的方法是在赤潮扩散之前探测出赤潮的发生。利用人造卫星资料和GIS技术,采用海色算法和空间分析技术进行赤潮的探测。本文按日为计量单位,利用HABAS程序表示出从1995年至2004年发生在韩国沿岸的有害性赤潮的空间分布、密度和生物种。空间分析结论是通过比较卫星资料和现场观测得出的。通过分类有害性赤潮地区分布,来完成对有害性赤潮初期发生地区的分析。 相似文献

Benzene formed a stable coinplex through its pi electrons to the copper ion in copper(II)montmorillonite. Copper(II)was the only exchangeable metal cation in montmorillonite to form a complex with benzene. Only those clay minerals whose charge arises in the octahedral layer produced the complex. 相似文献
