Abstract: Natural ventilate is important way to save energy for Public building in the area which is hot in summer and cold in winter. Atrium supports natural ventilate and it is good for ventilate. Analysis on atrium through several ways of winded pressure ventilation heated pressure ventilation and mechanical ventilation. Then uses ventilate Design and Ground Source Heat Pump to find suitable methods for design. At last, there is conclusion on different ventilate strategy for day and night, the way to come true and ventilate strategic management of technology. The purpose is finding the suitable methods for Public building energy saving and provide basis for ventilate design for energy saving building.

Abstract: According to the regional characteristics and climatic features in a cold region, interpret the relationship between building exterior pattern and energy-saving design by do the research on building size, building skin and construction design method,and explore how to combination of both, explore the possibility of the development of energy-saving building forms in a cold region on this basis, and enrich its architectural form vocabulary.

Abstract: Geological logging is a fundamental technical practice in a coal mine and also one of the most important technical jobs for the production of the coal mine, having important significance for the coal mine’s safe production and source recycling. Irregular shapes of the excavating faces make current photographic geological logging mode and methods unfeasible, so this paper studies critical techniques and methods of underground excavating face photographic geological logging in coal mines and proposes a new close-range photogrammetry control method, orienting the excavating face’s stereoscopic image using the directing laser and the plumb line, and proves through experiments that the positional accuracy of this method meets the requirement of the geological logging and that this photogrammetry orientation method is suitable for geological logging of the roadway excavating face images of coal mines.

Abstract: Yitong-Shulan fault, one north section of the famed Tanlu grand fault zone in eastern China, is NNE-trending though the Jilin Province, China. In October 2010, Heilongjiang segment of this fault was discovered the evidence of its activity in Holonce, and further inferred it is associated with a paleoearthquake event. So the recognize of Yitong-Shulan fault Jilin section active in the early Quaternary capable of generating moderate quakes is doubted. Yitong-Shulan fault is almost covered by Quaternary strata in Jilin Province. Traditional method is difficult to explore buried fault, and geophysical method is partial and expensive. The polarization remote sensing is a kind of emerging earth observation method, which has high terrain-recognization resolution. The polarization remote sensing method can to indentify the scarps and displaced geomorphic objects along the fault though satellite images. It even can to discover the high of scarps, displacement of geomorphic objects, and so on. The fault activity can be indicated well by the interpretation of polarization remote sensing. In this paper, use the polarization remote sensing method to study the activity of Yitong-Shulan fault Jilin section. Satellite image near the Shulan City, Jilin Province interpreted by polarization remote sensing reveals that the obviously linear scarps which extend long the fault is 1-3m high. Along the fault various kinds of geomorphic objects are displaced. This interpretation result indicated the Shulan-Shitoukoumen Reservoir segment of the fault is active since Holocene. The fault activity also is proved by geophysical method.

Abstract: The analysis of the difficulties of structure measurement of a stadium and the application of total station instrument spatial measurement technology specifically solve the control and measurement of the steel structure installation, location survey of the pre component installation, and the technical problems in the process of calibration measurement, which has ensured that the accuracy of the entire steel structure construction.

Abstract: Integer least square estimator is known to be optimal in GNSS ambiguity resolution. But it relays on a search in the whole ambiguity space which decreases the computational efficiency. A partial search strategy is proposed in this contribution. The new search is limited in an ambiguity space subset defined by the bootstrapping solution; the search-and-shrink approach is also introduced. Two experiments have shown the new search strategy promotes the computational efficiency a lot without a notable fixing property lost.

Abstract: Definitions of azimuthal conformal and gnomonic projections were introduced, and contrastive analyses of graticules shapes between these two projections were conducted. Based on theories of perspective azimuthal projection and space geometrical relationships, transformation between azimuthal conformal and gnomonic projections was carried out through series of derivation. Direct transformation formulae between coordinates of the two projections were established with respect to standard parallel. Finally, correctness and reliability of these formulae were tested and verified by numerical examples. The formulae could be widely used and enrich theories of projection transformation to a certain degree, which would offer reference value for charting in polar regions.

Abstract: In order to solve the problem of construction of 3D virtual campus, based on 3D modeling function of SketchUp,KML language,Southern CASS and free data and platform provided by Google Earth,technological routes and detailed solving methods of constructing virtual school were researched.Taking the Yuzhong campus of Northwest University For Nationalities as an example, this paper focuses on the technical process and operation skills of building three-dimensional model, texture mapping,3D model publishing in Google Earth. It has been proved that this method has the advantage of flexibility in the construction of 3D virtual campus which has guiding significance. In conclusion, the technology road map based on KML and Google SketchUp technology for 3D virtual campus system is feasible and practical and shows advantages in the aspects of model optimization and lightweight architecture..

Abstract: The template Contrast several methods applied in bridge deformation monitoring method, expounding the advantages and disadvantages of each method simple and clearly, providing guiding significance for practical engineering of bridge deformation monitoring.

Abstract: This paper researches the influence rule of unit size on relief amplitude by analyzing relief amplitudes under various statistical units and determines the optimum statistical unit in study area-Chongqing using the correlation between different statistical data. The results show that relief amplitude increased with increasing area of statistical unit, but increasing rate finally becomes stable. When determining the optimum unit using artificial drawing method, the point maintains stable can be found. The optimum unit area is 4km2 of SRTM-DEM data in study area.
