Abstract: This paper studies the related problems which belong to research of digital content platform by using numerical simulation. Results from the research show that: under effect of network externality, the digital content platform with high-tech stock could only expand successfully when the network size beyond critical capacity. But, when the technological gap is big enough, the critical capacity could be 0. Besides, we found the Nash equilibrium of R&D input is not necessary exist in the simulation without price, and the existence of equilibrium need special condition.

Abstract: Contrastive Studies of Pun in Figures of Speech. Pun as a figure of speech uses a word or phrase to get two meanings: literal meaning and connotation meaning so as to achieve humorous or sarcastic sense. There are many similarities between English and Chinese but in many ways they are different, while people always subconsciously consider them as equal and use them in any occasions. To solve these problems, this thesis solves them through the contrastive study of English and Chinese rhetorical figure-pun. By analyzing and comparing English and Chinese puns in some typical sentences and dialogues through semantic, pragmatic, cultural perspectives, partial tone, forms, meanings and so on. This thesis show that pun between English and Chinese exists lots of similarities and differences from different perspectives. Through all the endeavors done in this thesis, a better understanding of both languages and cultures, and smoother translation would be obtained. Whats more, people can use puns in English and Chinese languages properly so as to eliminate unnecessary misunderstandings when communicating with others.

Abstract: In order to avoid the problems of existing methods, a numerical simulation method for two-dimensional airflow over complex terrains is developed in this paper for the engineering use of flight dynamics. Based on the potential flow theories, the effects of terrains on the wind field are considered by a serial of two-dimensional vortexes, whose strengths are solved by combining with the ground boundary conditions. Numerical examples are studied by the proposed method, and the method is also evaluated by comparing the results with ones from the existing method. The result shows that the two-dimensional profile of complex terrains could be described by a cubic spline curve precisely. The computation procedure proposed in this paper is very simple and efficient, and it could provide a result of wind field with considerable accuracy. Therefore, this method could be used for flight principle evaluation and flight simulators. Finally, through simulate flight path, discussing effect of terrains on track.

Abstract: This paper studies the related problems which belong to research of digital content platform by using numerical simulation. Results from the research show that: the Nash-equilibrium is not the optimal outcome in the R&D competition. The government should pay attention to the continuity of investment. The larger the conversion rate of the user scale, R&D investment allowance rate and the foresight of companies are, the more the technology stock and consumer welfare are.

Abstract: In this paper, based on the formulated BISQ model including the Biot-flow and squirt-flow mechanism simultaneously, the elastic wave propagation in the isotropic porous medium filled with fluids is simulated by the staggered grid finite difference method. The perfectly matched layer method and the flux-corrected transport method are used to eliminate the effect of boundary reflection and numerical dispersion effect. The results of numerical simulation demonstrate that the method is effective.

Abstract: the Divine Proportion has a dominant position in the picture composition; however, the picture perfect dichotomy screen out by its reasoning can not solve the massive distribution. In traditional quickly composition, due to the impact of 4:3 TV format, people are accustomed to the screen is divided into nine cells, because they are used by equipment manufacturers to provide the average split-screen "Well-shaped" dividing line; With the prevalence of 16:9 high-definition TV and panoramic photography, photography cameraman shooting 16:9, this average segmentation approaches have failed to provide the composition with the help of. If you are still using the Divine Proportion different screen geometry segmentation, we can draw a dividing line position proportion that is consistent with the Divine Proportion in line with the physiological visual center of gravity of the human eye: 28:44:28; The new segmentation photography cameraman will provide a more convenient and quick reference picture composition.

Abstract: In order to improve the impartiality and objectivity of judicial expertise, the key problems about traffic accident speed identification are analyzed and the speed of vehicle is calculated by using the braking performance test report with reference to the national standard and automobile theory. The automobile dynamics of driver braking process is analyzed, all kinds of key problems such as the braking distance, braking coordination time, braking speed, longitudinal sliding coefficient of adhesion are combined with the braking performance test report, and the method of determining the longitudinal sliding coefficient of adhesion is proposed, the instantaneous velocity before the collision is calculated. Finally, the method is used to calculate the speed of an actual case, and simulated in the software of PC-Crash, the results are consistent, verifying that the speed identification method is correct.

Abstract: In Order to Achieve Accurate Quantitative Results of Parameters for Reservoir Pressure of Coal-Bed Methane, Neural Network Prediction Analytic Method is Adopted to Predict the Reservoir Pressure of Coal-Bed Methane. the Main Controlling Factors such as Conformation Stress, Buried Depth, in-Situ Stress and Permeability are Investigated. Mathematical Models of Neural Network of Reservoir Pressure of Coal-Bed Methane of Mathematical Analysis and System Architecture are Established; Taking the Qinshui Basin Coal Seam as Example to Forecast and use Reservoir Pressure of Coal-Bed Methane. Projections Show that: the use of Neural Network Prediction of Reservoir Pressure of Coal-Bed Methane is Feasible; Neural Network Method Makes up a Mathematical Point of Linear and Regularity in Order to Solve the Non-Linear Complex Relationship between the Input and Output Parameter Variables.

Abstract: Domestic power marketing system means more backward, and the marketing organization system is imperfect. Due to business expansion and increased market competition, Tianfu thermoelectric original electric gas marketing system can no longer meet the needs of enterprise development which lead to information islands. According to the current operating status of the joint stock company and existing problems, this paper study a large marketing integration model, and constructed a marketing network management system platform integrated with electricity, heat and gas for the thermal power enterprises. the establishment of an integrated marketing platform with electricity, heat and gas business is built on a unified infrastructure platform in order to unify customer information, marketing basic platform capabilities and customer service platform function, centralize management of electricity, heat, gas marketing business in one of a big marketing intensive management mode including electricity, heat and gas.
