陀螺定向钻进中孔口锁的改进及应用

在煤田陷落柱内施工注浆孔时,常需要施工分支孔,陀螺定向钻进是施工分支孔的手段之一,陀螺定向能否锁定已定好方位的入孔钻具是定向成败的关键一环.针对以前孔口锁锁定入孔钻具的弊端,提出了一种新孔口锁结构.该孔口锁由四部分组成上半部、下半部、固定螺丝、支撑腿.改进后的孔口锁既能方便锁定入孔钻具,又能提高定向中靶率.

A Bayesian approach to the detection of gross errors based on posterior probability

Existing methods for gross error detection, based on the mean shift model or the variance inflation model, have hardly considered or taken advantage of the potential prior information on the unknown parameters. This paper puts forward a Bayesian approach for gross error detection when prior information on the unknown parameters is available. Firstly, based on the basic principle of Bayesian statistical inference, the Bayesian method—posterior probability method—for the detection of gross errors is established. Secondly, considering either non-informative priors or normal-gamma priors on the unknown parameters, the computational formula of the posterior probability is given for both the mean shift model and the variance inflation model, respectively, under the condition of unequal weight and independent observations. Finally, as an example, a triangulation network is computed and analyzed, which shows that the method given here is feasible.     

兰坪盆地水泄铜(钴)矿床石英的40Ar-39Ar快中子活化年龄

选取水泄铜(钴)矿床主成矿阶段的石英样品进行⁴⁰Ar-³⁹快中子活化法同位素地质年龄测定,获得坪年龄59.2±0.8Ma,对应的等时年龄为59.8±0.5Ma,反等时线年龄为59.9±0.1Ma,三者在误差范围内完全一致,都可代表矿石的形成年龄。该年龄与兰坪盆地铜多金属矿集区的矿床形成时代一致,反映包括水泄铜(钴)矿床在内的区域矿床形成于喜马拉雅造山运动早期统一的构造地质背景之下,受同一期构造—热演化事件的制约。

The integrated spatial databases of GeoStar

GeoStar is the registered trademark of GIS software made by WTUSM in China.By means of the GeoStar,multi-scale images,DEMs,graphics and attributes integrated in very large seamless databases can be created,and the multi-dimensional dynamic visualization and information extraction are also available.This paper describes the fundamental characteristics of such huge integrated databases,for instance,the data models,database structures and the spatial index strategies.At last,the typical applications of GeoStar for a few pilot projects like the Shanghai CyberCity and the Guangdong provincial spatial data infrastructure (SDI) are illustrated and several concluding remarks are stressed.

地震时间序列多重分形计算精度估计

目前计算地震时间分形的方法很多,但具体各种计算方法的误差（或精度）是多少,还没有一个定量的结果。本文针对这一问题,利用Ｃａｎｔｏｒ多分形集理论模型数值模拟来估算其精度（误差）,进而解决了限、离散、点集的多重分形维数谱的计算精度（误差）估计问题。通过一维（时间）理论模型数值模拟得出如下结论：（１）存在尺度问题、样本容量问题、基准点选取问题、不同计算方法差异等;（２）固定质量（ＭＡＳ）法和最小生成树（     

The Precision Estimate of Multi-Fractal Methods of Time Sequence of Earthquakes

At present,there are many methods of calculating seismic time-fractal.However,there isn’t aquantitative result about the precision of every method.So,in this Paper,we use the digitalimitation of theoretic model to solve precision estimate problems of calculating the precision ofone dimension distribution of theoretic models with Cantor multi-fractal set,we obtained someresults as follows:(1)There exists many problems such as rules,numbers of samples,basicpoint selection,the diffence resulted from different methods and so on.(2)The fixed-massmethod(MAS)and the minimal spanning tree method(MST)can give good structure charac-teristics with different q value,while the counting-boxes method can’t.And the error of thefixed-radius method(RAD)in the range of-q is too big.(3)There are scale problems of rulesfor multi-fractal,it is objective reflection for non-rule area.(4)MST has the boundary prob-lem,while MAS and RAD don’t.(5)With increasing sample number,the precision of allfractal-dimension values becomes
