Cars are not only a means of transportation, but also a yearning for a better life. Electronic information technology and intelligent technology are the most emerging hot technologies at present. How to apply electronic information technology and intelligent technology to the automotive industry and promote the transformation, upgrading, reform and innovation of the automotive industry is a problem that we need to think seriously. Because electronic information technology is widely used in the whole society, and its application in automobiles is also classified. Therefore, it is very important to optimize the overall performance and improve the reliability of automobiles. The application of electronic information technology and intelligent technology in automobiles also has a very bright prospect.展开更多

By combining application and finish books of science and technology support plan project in agricultural field of Ministry of Science and Technology with stronger innovation,case analysis and expert interview are conducted. Evaluation indexes of agricultural science and technology project based on innovation value are proposed initially,and there are 50 initial indexes. After that,via focus group talk,qualitative research is conducted to further adjust innovative evaluation indexes,and 50 initial indexes are deleted to 41. The importance of the 41 indexes is scored by the experts,and index screening and classification are conducted by verification factor analysis in structural equation model. It not only obtains index classification but also finds action mechanism among innovation demand,innovation mode,research thinking,treatment method of difficulty,and predicted risk. The research could straighten up ideas of project review experts in agricultural field and provide reference for applicant designing project.展开更多
