1 Introduction The Qinghai-Tibet Plateau, known as the highest plateau with the most complex topography in the world, covers an area of more than 200km2, with a mean elevation of more than 4000m a.s.l. (Ye and Gao, 1979). Surrounded by the Earth’s highest mountains, such as the Himalayas, Pamir, Kunlun Mountains, the plateau plays a significant role in climate change in China even in the world, thus attracted great attention of researchers. Up to now, many achievements have been gained by…  相似文献   

水准测量资料中的地形效应     

王家富  张希 《大地测量与地球动力学》1992,(1)

本文首先用有限元方法对几种不同的地形模型进行了分析。所得的结论是:由于实际地球表面地形的起伏不平,水准测量资料与地形之间具有相关性,即水准点高程变化与该点高程之间呈相关性。最后,本文对今后水准测量资料的分析处理提出了建议。  相似文献

Age-metallicity relation for F-stars     

Hong Bae Ann  Yong Hee Kang 《Astrophysics and Space Science》1986,118(1-2):325-327

We derived the age-metallicity relation for the solar neighbourhood from theuvby, H photometry of F-stars using the evolutionary models of Hejlesen (1980). It is shown that disk formation is divided into two phases according to the fast and slow collapse which accompany the initial rapid enrichment and slow increase of the metallicity of the galactic disk, respectively.Paper presented at the IAU Third Asian-Pacific Regional Meeting, held in Kyoto, Japan, between 30 September–6 October, 1984.  相似文献   

实验条件对X射线衍射物相定量分析结果的影响   总被引：8，自引：6，他引：2  

房俊卓  张霞  徐崇福 《岩矿测试》2008,27(1):60-62

通过实验验证了多物相试样X射线衍射定量分析的基体效应,着重研究了参比强度K值、衍射强度、混合物各物相粒度、X射线管功率等实验条件对物相定量分析结果的影响。结果表明,物相定性分析是定量分析的前提,采用积分强度、使各物相颗粒尽可能细而且均匀、采用较高的X射线管功率以及适合的扫描速率均有利于提高物相X射线衍射定量分析的准确度。  相似文献

贵州普定陈旗堡地区土体主要理化性质与持水量相关性研究   总被引：2，自引：0，他引：2  

王玉英  阎长虹  陈明珠  郭军辉  詹启伟  郑军  陈喜 《地质论评》2008,54(4):550-556

根据贵州普定陈旗堡典型喀斯特地区的生态特性,从水文地质与工程地质角度,借助土壤学对土壤水分特性的研究理论,对表层土壤20cm以下土层的土体物理化学性质与土体水分含量,即土体的持水量（waterholding capacity),进行了相关性研究。分析结果表明：土体颗粒成分、孔隙比、矿物成分含量等对土体水分含量均有影响。土体中粉粒含量较高而粘粒含量较少,且粒度分配不均匀时,土体水分含量相对较高;孔隙率高的土体水分含量较高;伊蒙混层矿物、伊利石和绿泥石等粘土矿物含量较高时,土体水分含量相对较高,而长石、碳酸盐等原生矿物含量较高时,土体水分含量相对较小。石英对于土体持水量影响不明显。  相似文献
