在AutoCAD200O中应用VBA技术自动绘制等高线

应用AutoCAD进行地形图的计算机辅助制图能极大地提高工作效率，但因其没有根据数字地形分析（DTM模型）自动产生等高线的功能，用VBA编程技术，将外业采集的离散点通过建立三角网，在三角形边上内插等高点的方式，能在AutoCAD中实现等高线的自动绘制。

不均匀地基应力集中与地基计算

受浅埋岩层影响，土质地基易产生应力集中。一方面，应力集中程度过大易使地基发生强度破坏，另一方面，应力集中促使厚度偏薄地段产生较大的沉降，从而使整个地基的变形趋向协调。笔者根据多年的工作实践，以叶戈罗夫（К.К.ЕГоров) 关于应力集中理论为基础，以工程为实例，分析了不均匀地基中应力集中程度与基础宽度，压缩层厚度的关系，计算了应力集中对地基强度与变形的影响，提出了在不均匀地基的计算过程中不宜应力集中问题。

Investigations on the Quaternary Glaciation in the Khumbu Himal (Nepal, East-Himalaya)

Based on geomorphological field work the mapping of former lateral/terminal moraines in the middle segment of the Bhotekoshi Nadi is quite similar to the geomorphological findings of Heuberger (1956: Fig. 2). The deductive calculation of the equilibrium line altitudes is oriented on the reconstructed types of former glaciers. Based on the geomorphological findings of this valley segment the relation of Neoglacial and Late Glacial ice margins of the glaciers of the tributary valleys of the Bhotekoshi Nadi is not conclusive. A post-late glacial maximum snow-line depression of at least 950 m has not obligatory caused an ice fill of the Bhotekoshi Nadi below 3200 m. This revised version was published online in July 2006 with corrections to the Cover Date.     

An Overview of Dissolved and Suspended Matter Fluxes in the Loire River Basin: Natural and Anthropogenic Inputs

The spatial and temporal distributions of major elements were investigated in the surface waters and in associated suspended matter at two sites of the upper Loire basin (Orleans and Brehemont) between 1995 and 1998.According to geochemical and isotopic patterns, the dissolved load appears to result from a process of mixing rainwater inputs, weathering processes of carbonate and silicate bedrock, and agricultural and urban inputs. Natural inputs influence 60% of water chemical composition at both sites. Annual dissolved fluxes were estimated to be 1300 10³ t/y at Orleans and 1620 10³ t/y at Brehemont. Major elements are transported mainly in the dissolved fraction. After correcting for atmospheric and anthropogenic inputs, the silicate specific export rate was calculated to be 11 t/y/km² throughout the basin and the carbonate specific export rate to be from 47 t/y/km² at Orleans to 23 t/y/km² at Brehemont.The suspended load appears to result from at least two particle reservoirs: a silicate reservoir and a carbonate reservoir. The silicate reservoir has a detrital origin, mainly during periods of high flow, while the carbonate reservoir has a detrital origin during periods of high flow and an authigenic origin during periods of low flow. Of the total annual flow of suspended matter, this authigenic material represents 16% at Orleans, 25% at Brehemont and 37% in the fluvial part of the estuary. After correcting authigenic inputs, the specific export rate due to mechanical weathering was estimated to be 8 t/y/km² throughout the Loire basin.

在矿产储量管理上应改革沿用的静态工业指标初探

50年代引进前苏联在地勘工作中用静态法制订工业指标、计算矿产储量,为矿山建设提交可供设计利用的矿产储量方面,曾经起到巨大的推动作用。然而,随着改革、开放,上述方法就不能适应市场经济发展的要求,本文试图在剖析静态法制订工业指标、计算矿产储量的四个弊端的基础上,探讨用贸易指标计算矿产储量来取代以往那种用静态法制订工业指标计算矿产储量的管理方法。
