It was found that electrical field strength and potential around the the sample changed less in the fully insulated chamber than in conducting material phytotron, so it is closer the real condition. Based on the design, the first fully insulated large artificial climate chamber in China, in which temperature , humidity, and atmospheric pressure can be regulated, has been built in our laboratory. The paper developed an insulation parameters automatic test system of high voltage capacitive equipment based on LabVIEW. In the chamber, On-line tanδmeasurements of the capacitive transformer bushings were completed. The effects of environmental factors on tanδwere analyzed, and the curves between the tanδand the environment parameters were acquired. Then, a grey relational model to analyze the effects of main environmental factors on tanδwas built, and the grey relational grade between them was gained in this paper.

The four models were analyzed and normalized. We studied the procedure and method of building forest fire model base. Model base was build by object-oriented method based on category of model. Forest fire spreading models algorithm were implemented. We designed model dictionary base, model file base, and model knowledge base. Model base administration and maintenance functions were developed and implemented model file management, parameter management and knowledge management. The problems of interface between of model base and database were solved by means of model data control files. Model base ensured the availability of supporting for forest fire model suitability selection technology and forest fire model self-adapting updating technology.(3) Based on BP artificial neural network, we designed a frame construction of forest fire model selection of suitability. Forest fire model selection knowledge was produced through BP artificial neural network.

In order to escplore the new models of cultivating in school, the essay tightly connects cultivating with teaching and research activities, based on developing teachers vacational level by modern information technoledge. Besides, during the process of founding the system of trainning teachers in school, we decide on our cultive target—promote the element educational reform by school internet, combing the facts of different schools. The cultive contnet should suit measures to different conditions, trying to synthesise and stress its practical function. When carrying out the cultive plan, we should sum up different models and explain its essence, steps and function so that we make the best choice. As to evaluational methods, we can take varied evaluational ways, including self-evaluation and evaluating each other by combination of fixing quality and quantity. At last, it is very necessary to found a special organization in order to form cultive web, make entire standarization, pay attention to develop resource and provide cultive guarantee.

Yet most of the Chinese rich also have the most important trait: They're related to a top government official. A 2006 study by several Chinese research institutions showed that almost 90% of the country's top leaders in sectors encompassing finance, foreign trade, property development, construction, and stock trading were princelings, or offspring of top government officials.

不过，大多数中国富人还有着最为重要的特性：他们都与政府高官有关系。2006年中国几家研究机构进行的一项调查显示，中国与金融、外贸、地产开发、建筑以及股票交易有关的行业中，将近90%的商业领袖都是政府高官的子女。
