The digital campus information unified portal can provide the services not possessed by traditional campus network. Firstly, the portal technology and the relation with Portlet are analyzed for the secondary development of liferay technology; secondly, the digital campus portal system is realized according to the requirement analysis of the digital campus portal system and the system development principles as well as the system implementation characteristics. Unified portal system, SSO (Single Sing-on) unified identity authentication and campus workflow system are realized in this paper. Meanwhile, this design scheme can not only support the integration of data, contents and information, but also transfer the contents, application programs and services inherited thereby through the customizable portal channel, thus to reduce the operation cost of the campus information portal and improve the working efficiency of the users as well as play an important role in digital campus construction. This portal system design scheme has been applied in the digital campus system of Southwest Petroleum University, and is practicably proven to have certain feasibility and practicability.

Traditional method of drying corn is using higher temperature to dry quickly. But high drying temperature can make the corn lost nutrients. Provide the foundation of designing a new corn drier which can dry corn efficient as well as sustain nutrition.Optimization analysis on distribution of temperature of a corn by Fluent. It shows that:1).Hot winds is 0.8m/s，temperature is 343K. Temperature distributions of corn is evenlier. The highest temperature is below 333K.2).More fluid inlet make corn evenlier. Change the angle between corn and velocity vector will not impact the temperature distributions of corn.

This article adopts samples from farmland soil in Zhang Yi Zhan, Shenyang City, where is located in China’s northeastern industrial polluted area, assisted by systematic absorption test and soil column device and measuring system, to conduct in-depth study on the transfer rule of a persistent pollutant-organochlorine pesticide (OCP) BHC in soil, by which we could obtain the spatiotemporal variation process of pollutant concentration in unsaturated soil column under certain pollution transport condition. The experiment result indicates, that by comparing the leaching curves of each soil column filled with sample soil collected from various soil layers across the district, we could find that the transfer velocity of BHC in the vadose zone of soil column No. IV（60~80cm) was faster than that in No. I（0~20cm), No. II（20~40cm） and No. III（40~60cm）, while that in No. V （80~100cm）was the maximum. This was possibly due to its close to upper soil layer where high content of clay and organic matter exist, while the lower soil layer was nearly sandy with low content of organic matter. However, the proved research shows, that soil's absorptive capacity to BHC would grow with an increase of organic matter content, therefore, the soil column No. V had smaller absorptive capacity than No. IV, and much smaller than No. I, II and III, extending the transfer capacity of pollutant to a larger degree. Namely, once the water body polluted by OCP reached to the lower soil layer of vadose zone, its transfer velocity would accelerate, which could be potentially hazardous to ecological system and underground water. Thus to research on the transfer characteristics of BHC in each soil layer of vadose zone would be of great importance as it would provide theoretical basis for improvement and restoration of soil and underground water pollution.

The extent of damage caused by heavy snowfall and strong winds in extreme weather conditions has recently been increasing. Accordingly, a great number of plastic greenhouses have been damaged by typhoons in summer and heavy snowfall in winter each year. In this study, a system that monitors the structural health of horticultural facilities using acceleration data is proposed. This system analyzes data obtained by structural health monitoring sensors and informs users of problems that have occurred in horticultural facilities through a client. In addition, the system proposed in this study has been designed, implemented, and tested to ensure it can detect a change in the location of an object that has been moved.

It has never been an outdated topic to discuss how to construct and improve the residential urban area in the process of territorial development. The challenges and problems of creating a residential urban area are always associated with the issues of human beings, relations and activities among human, the district surrounding, etc. For instance, the creation of urban areas for human beings may be harmful to the environment and cause more population pressure problems. Hence, the creation of residential urban area does not only bring advantages, but is also connected to problems. To manage it carefully it is necessary to consider sustainable development, which stresses that environment should not be separated from development. Diverse approaches have been used for measuring the sustainability, as it reflects relationship between human beings and the systems of environment. Based on the approaches, sustainability assessment is utilized to assess the overall improvement of sustainable development. In the context of the sustainability assessment, the purpose of this article is to integrate two diverse approaches, including the systems of environmental indicator and the analysis for early warning. This paper also aims to offer a tool that helps the decision maker to measure whether the development of residential urban areas are sustainable and healthy or not, and prevent problems in advance so that urban areas develop healthily and quickly. Hence, this paper analyzes how to create proper early warning indicators and appropriate approaches and modeling that can be utilized for the analysis. To provide sufficient evidence to this article, a real case is discussed in this paper that is connected to the evolution of a residential urban area in China.

In this study, indoor illuminance and daylight distribution compared to the generation performance of PV window system are experimented and analyzed in accordance with the types of silicon (crystalline, amorphous). According to the analysis of generation quantity during the measurement period, when solar radiation is 138.1kW, daily maximum generation quantity is 27.4kW (19.8% of efficiency) for crystalline PV window system, and 5.8kW (4.1% of efficiency) for amorphous PV window system. In addition, according to analysis of indoor illuminance and daylight distribution, the illuminance of 500lx is secured from all measuring points, and in the case of daylight factor, more than 1.5% of minimum standard (BS 8206-2) is indicated. Therefore, it is analyzed that the lighting performance required by residential environment is satisfied by crystalline as well as amorphous PV window system. However, in the case of illuminance uniformity, crystalline PV window system are analyzed to be 10.5% lower for the measuring height of 400mm and 48.6% lower for the measuring height of 850mm compared to the amorphous PV door and window system.
