Ein Präzisionszeitskalenschreiber mit Dekadischer Frequenz-Unterteilung für Zeitmarkierung und Frequenzmessung     

Prof. Dr. Max Müller 《Pure and Applied Geophysics》1949,15(3-4):220-226

Zusammenfassung Es wird ein Präzisionszeitskalenschreiber mit fünffacherdekadischer Frequenzunterteilung für Zeitmarkierung und Frequenzmessung beschrieben, der aus RC-Schwingungskreisen mit Gasentladungsröhren besteht, in deren Entladungskreis sich eine Registrierschleife befindet. Der erste Kreis wird nach einem Uhrenprinzip durch eine Stimmgabel synchronisiert, wobei zwecks Erhöhung der Genauigkeit der Antrieb stets im Nulldurchgang erfolgt. Die Synchronisierung der weiteren Kreise erfolgt in der Weise, dass man dem Gitter des Kippschwingungskreises Spannungsstösse des davor liegenden Kippschwingungskreises überlagert, und zwar derart, dass die Zündung bei jedem zehnten überlagernden Stoss erfolgt. Die freien Kippschwingungen werden dabei zu erzwungenen zwangläufig synchronisierten Schwingungen. Die Frequenzunterteilung erfolgt in fünf Dekaden (1000, 100, 10, 1 und 0.1 Hertz).

Summary A new time marking arrangement is described, developped by the Author, based on the application of thyratrons, synchronized by means of a tuning fork, and recording automatically a scale, which is subdivided in 5 decades and which works with extremely high exactness. The arrangement is synchronized by means of a clock principle.

Joint two-dimensional cross-gradient imaging of magnetotelluric and seismic traveltime data for structural and lithological classification   总被引：3，自引：0，他引：3  

Luis A. Gallardo  Max A. Meju 《Geophysical Journal International》2007,169(3):1261-1272

Collocated magnetotelluric (MT) and seismic profiling is emerging as a necessary combined approach for deep and near-surface imaging but the resulting experimental data are typically interpreted separately since no production programs exist for multidimensional joint inversion of MT and seismic data. We present a joint 2-D inversion approach for imaging collocated MT and seismic refraction data with cross-gradient structural constraints. We describe the main features of the algorithm and first apply it to synthetic data generated for a hypothetical complex geological model. For the synthetic data, we find that the scheme leads to models with remarkable structural resemblance and improved estimates of electrical resistivity and seismic velocity. We apply the scheme to near-surface field data to test the consistency of a previously suggested resistivity–velocity interrelationship and its potential use for subsurface lithofacies discrimination or structural classification. The MT-seismic relationship is found to be in excellent accord with that derived previously for DC resistivity and seismic data set at the test site. Our results suggest that joint MT-seismic cross-gradient imaging leads to improved characterization of heterogeneous geological targets at near-surface to mantle depths.  相似文献   

Australia's Box–Ironbark Forests and Woodlands: saving the fragments of a threatened ecosystem     

Max Kelly 《The Australian geographer》2005,36(1):19-37

Australia's box–ironbark forests and woodlands once covered about 14 per cent of the State of Victoria on the riverine plains and foothills of the Great Dividing Range. But approximately 83 per cent of the total original habitat has been destroyed and what remains of this significant ecosystem is now highly fragmented and vulnerable to further degradation. Moreover, only 14 per cent of the area remaining is on public land. A 10 year campaign on the part of the environmental movement eventually succeeded in forcing the State government to conduct an independent inquiry into this ecosystem and make recommendations on future management. This paper outlines the innovative public participation process adopted by the Victorian State government and the outcomes of the inquiry. A subsequent compensation package for commercial operations disadvantaged by the proclamation of a series of new national parks is also discussed, as are the shortcomings of a process that can have little or no impact on what happens on private land.  相似文献   

Palaeovalleys and fault-controlled depocentres in the Late-Ordovician glacial record of the Murzuq Basin (central Libya)     

Jean-François Ghienne  Max Deynoux  Giänreto Manatschal  Jean-Loup Rubino 《Comptes Rendus Geoscience》2003,335(15):1091-1100

In the Gargaf area, the stratigraphic architecture of the Late-Ordovician glacial drift results from successive glacial erosion events, with the location of the main glacial valleys partly controlled by inherited Panafrican structural trends, and by the existence of glacio-isostatically induced fault-related depocentres. Four laterally discontinuous, depositional units correspond to the filling of palaeovalleys. Each of the corresponding basal bounding surfaces was incised during a major ice front advance, reaching at least the northern Gargaf (>28°S). The bulk of the glacial record is made up of fluvial to shallow-marine sediments deposited in relatively distal glacial environments. Each unit, which recorded a glacial-interglacial climatic cycle, can be used for correlation throughout the Murzuq Basin and even at the scale of the North Gondwana platform.

International cities: some geographical considerations and a case study of Montreal     

Max Barlow  Brian Slack 《Geoforum》1985,16(3):333-345

Several cities perform important international functions to such an extent that they may be described as international cities. This paper discusses their activities and influence with a view to establishing a conceptual framework for geographic research. A major argument is that there are opportunities for geographers to utilise familiar concepts and approaches in a new context, and to contribute to a research problem which has both theoretical and applied significance. The paper also discusses the case of Montreal, examining a number of its internationally oriented activities.  相似文献
