By using the second version of the Community Atmosphere Model (CAM2) of NCAR, the general circulations of the Earth's atmosphere were simulated under different obliquity condition. The results imply that three-cell circulation turn weak when the obliquity turn large except that the three-cell circulation in Northern Hemisphere in winter, Hadley circulation in Southern Hemisphere in spring and Hadley circulation in Southern Hemisphere in summer turn strong with the obliquity turns large. For annual mean three-cell circulation, its intensity turns weak with the obliquity turn large. The extension of Hadley circulation in Southern Hemisphere turn large when the obliquity turns large, while the extension of Hadley circulation in Northern Hemisphere and Ferrel circulation in Southern Hemisphere turn small with the obliquity turns large. The ascending branch of Hadley circulation in the Southern Hemisphere turn strong significantly under the 60° obliquity condition then normal obliquity of Earth. Furthermore, for annual mean the extension and the velocity of easterly wind in stratosphere over the equator turn large when the obliquity turns large. While the extension of the westerly wind turn small with the obliquity turns large. With the obliquity turns large, the strength of jet stream in Northern Hemisphere turn weak, the strength of jet stream in Southern Hemisphere turn strong. The same characteristics for the four seasons are that with the obliquity turns large, the easterly in the troposphere and westerly in the Northern Hemisphere turn weak, the strength of jet stream at mid-latitude in Northern Hemisphere turn weak. The difference are that with the obliquity turns large, the strength of jet stream at mid-latitude in Southern Hemisphere in spring turn strong, the westerly wind at middle and high latitude have opposite change trends in summer and autumn in Southern Hemisphere, the global westerly wind in winter turn weak.

GAMIT is one of the best baseline solution software for high precision GPS data processing. For a certain high precision GPS network with massive data and multiple sessions of single day, the script sh_gamit or others approach fails to achieve batch processing for GPS observations. It is still solved via step by step. However, it's so cockamamie and inefficient for solving. Base on deathly studying and discussing the approach to baseline solution batch processing for high precision GPS network with massive data, this paper proposed an algorithm of baseline solution batch processing for high precision GPS network—named GBSBPA algorithm. And then, we realized the GBSBPA algorithm base on Bash programming language. Finally, it integrated with baseline surveying engineering high precision GPS control network for the experiment of the GBSBPA algorithm analysis and test, and effective and feasible of the GBSBPA algorithm was verified and automation batch processing of GPS network with massive data was achieved, and we obtained satisfying results.

The global warming is mainly caused by the rapid rise of greenhouse gas concentrations in the atmosphere. To reverse the trend, the world resorts to the low-carbon economy. The agricultural ecosystem, the largest artificial ecosystem ever seen in the world, is the second largest source of greenhouse gas emission, establishing the close relation between the agriculture-related activities and global warming. The thesis studies the Three Gorges Reservoir areas and estimates the paddy rice field CH4 emission quantity in the areas. It estimates that in 2008 the paddy rice field CH4 emission quantity stood at between 55,000 and 65,000 tons. The thesis also proposes measures to reduce the emission, including the protective farming, change of traditional farming models, rational and accurate fertilizing, reform of the paddy rice field management techniques, management of time and space differences in the paddy rice field, developing the mountainous composite eco-agriculture and sectors with local features.

Based on layered elastic theory, the compressive strains at the top of subgrade were predicted using BP neural network. According to the types of pavement structure in common use, the database of surface deflections with their corresponding structural parameters based on layered elastic theory was established. BP neural network was developed using the established database and was used to predict the compressive strains at the top of subgrade. The predictive effect of compressive strains at the top of subgrade backcalculated by theoretical deflection basins was tested. At the same time, generalization ability of the developed BP neural network was verified. It indicated that error of the compressive strains at the top of subgrade predicted by the developed BP neural network and the theoretical values calculated by layered elastic theory program was within 6%. It would provide the references with the model of BP neural network to estimate the health conditions of subgrade.

Underwater gas jet produces a complex unstable multiphase flow field, which is involved in different technological fields. The VOF multiphase flow model and the RNG κ - ε turbulence model were adopted to predict the structure of underwater gas jet flow field and to reveal the development of transient flow. The features of the developing process of the two phase flow, and the basic characteristics of the jet flow under the influence of the complex compression and expansion waves were revealed. The simulated results are in good agreement with experimental data, and thus indicate the accuracy of the proposed method.

In this paper 9 asphalt plates are made with the same grading curve of AC but different aggregate types. The asphalt plates were polished with real tires by the Aachen polishing machine, which was constructed by the Institute of Road and Traffic Engineering Aachen. The friction value was measured at 100 km/h in accordance with Wehner/Schulze test apparatus after each stage of polishing. The result showed that the long-term grip resistance of AC pavement depends mainly on the polishing resistance of the aggregates.

Low carbon economy is a new economic mode of low energy consumption, low pollution and low emission. It is a great progress of human society after the agriculture civilization and industrial civilization. As a form of low carbon economy, low carbon tourism represents the trend of the world's tourist industry. Low carbon economy mainly includes three factors: macroscopical low carbon decision-making, microcosmic low carbon production and low carbon consumption. Based on the “trichotomy” of low carbon economy, the article redefines the low carbon tourism, analyzes the differences and links among low carbon tourism, eco-tourism and sustainable tourism. Then it expounds the “Trinitarian” constructing mode of low carbon tourism: macroscopical low carbon decision-making (government: low carbon environment creation), microcosmic low carbon production (tourist enterprises: low carbon management innovation) and low carbon consumption (tourists: low carbon lifestyle transformation).

Since 1 of the 20 detectors in Terra MODIS band 5 (1.230∼1.250 µm) are noisy, there are sharp and repetitive stripes over the entire image. As for MODIS geolocated data, the stripes are irregular and sometimes uncontinuous, it brings a difficult problem to the image retrieving process. This paper presents a detection method to extract the stripe noise, and a maximum a posteriori (MAP) based algorithm to correct the contaminated pixels. In the MAP method, the likelihood probability density function (PDF) is proposed based on a linear image noise model, and a Huber-Markov model is employed as the prior PDF. The gradient descent optimization method is used to receive the destriped image. The proposed algorithm has been tested using a Terra MODIS band 5 geolocated image. The experimental results demonstrate that the proposed algorithm performs well.
由于Terra MODIS波段5(1.230 ~ 1.250µm)的20个探测器中有1个存在噪声，因此在整个图像上存在尖锐且重复的条纹。对于MODIS定位数据来说，条纹是不规则的，有时甚至是不连续的，这给图像检索带来了难题。本文提出了一种提取条纹噪声的检测方法，并基于最大后验(MAP)算法对污染像素进行校正。在MAP方法中，基于线性图像噪声模型提出了似然概率密度函数，并采用Huber-Markov模型作为先验似然概率密度函数。采用梯度下降优化方法接收去条纹图像。该算法已在Terra MODIS 5波段定位图像上进行了测试。实验结果表明，该算法具有良好的性能。
