Fast space-domain evaluation of geodetic surface integrals

Geodetic surface integrals play an important role in the numerical solution of geodetic boundary-value problems. In many cases they can be evaluated using fast methods in the frequency domain (FFT). However, this is not possible in general, because the domain of integration may be non-trivial (as is the surface of the Earth), the kernel function may not be of convolution type, or the data distribution may be heterogeneous. Therefore, fast evaluation strategies are also required in the space domain. They are more difficult to design because only one property is left where a more or less fast evaluation strategy can be built upon: the potential type of the kernel function. Consequently, the idea is not to replace well-established frequency domain techniques, but to supplement them. Our approach to this problem goes in two directions: (1) we use advanced cubature methods where the integration nodes automatically densify in the vicinity of the evaluation points; (2) we use powerful computer hardware, namely MIMD computers with distributed memory. This enables us to evaluate geodetic surface integrals of any practical complexity in reasonable time and accuracy. This is shown in a numerical example.

湖南黄金洞金矿毒砂中Au赋存状态的电子探针研究

本文利用ＪＸＡ－８８００Ｍ超大型电子探针，以湖南黄金洞金矿含金毒砂为研究对象。利用金特征Ｘ－射线扫描方法和微区含金含量，对不可见金赋存状态的研究方法和温试条件进行了探索，先观察背散射电子图像，排除金在含金矿物毒砂中呈显显微颗粒存在的可能性，继而用ＬｉＦ晶体测定金Ｌ＝８８．７６Ｌａｌ峰位，然后逐渐放大倍数（ｘ３００，ｘ１０００，ｘ５０００，ｘ３００００，ｘ２０００００）进行金特征，Ｘ－射线连续测量，，结果发现金元素总 是均匀分布在重砂中，从而证实了金呈品格金形式存在的推测。

CYBERSPACE AND VIRTUAL PLACES

ABSTRACT. Computer networks are often described in terms that imply a virtual space or place: electronic frontier, cyberspace, and information superhighway have been used to indicate computer networks as a whole; cafés, dungeons, and virtual offices are some of the “places” people refer to as being in or on networks. The use of this language, which I collectively call “virtual-place metaphors,” indicates three broad metaphorical themes: virtual architecture, electronic frontier, and cyberspace. The metaphors encourage control, surveillance, and capitalist expansion through computer technologies—and also evasion and resistance through computer technologies.     

X2检验假设分布有效性的岩体工程应用

在工程地质问题中许多现象是不确定、且具有随机分布的特性，而这种随机分布特性往往可以采用某种形式的密度函数来描述。采用Ｘ２检验假设分布有效性是一个重要的方法，采用该法可以获得观测数据最佳拟合的概率模型，通过自编程序可以同时检验多种概率密度函数并选取最佳模型。本文将介绍这一方法，并通过一个实例加以说明。
