Owing to the special work environment of aquatic products processing workshops，its real-time monitoring of temperature becomes particularly important. Meanwhile，as different types of production workshops of aquatic products processing workshops work under different environmental requirements，a number of test samples point to implement all-round environmental data collection are needed．And in view of the scale of demand condition of monitoring system，sampling the CAN-bus network based on the distributed bus can meet the requirements of the communications network．Therefore，using advanced computer monitoring and control technologies to achieve the scene temperature monitoring system, which is as a part of a digital，intelligent，and a new network workshop management system. The system has a certain degree of practicality and the value of promotion．

The computer multi-media technology is to transform a series of media messages (such as the text，images，video，audio，animation) into digital information．And at the same time，it can display this digital information by friendly interface．Combining with the actual work experiences，this paper discusses the application of multimedia technology mainly from the aspect of multimedia teaching．

Along with the increase of commercial residential buildings，developers’ requirement for housing management is rapidly increasing and the informationization of business management has become a trend．This paper illustrates the design of the overall structure，the construct of the system and the key techniques adopted by the system，with the background of the actual design and development of the housing management information system．

The administration and maintenance of the universities’ computer laboratories are the key to make teaching experiments go smoothly．Taking the computer lab of Nanjing University of Finance and Economics as an example，the program encountered in the computer lab is analyzed．The application effect of PNS (Pre-environment Network System) in the computer lab is also discussed．

Partial scenarios are the requirements typically provided by different stakeholders according to their personal knowledge and the business functions they cared；while the result is that those descriptions of the requirements often have some limitations because different users have respective knowledge background and limited knowledge of the field only with their individual point of view．In this essay，systematic behavior is described by modal transition systems；in addition，the related knowledge of domain features is introduced and evolution of partial scenario is demonstrated accordingly，which help improve to meet the stakeholders’ requirements．Finally，the paper illustrates the effectiveness of the method through an example．

Higher vocational education is an important part of higher education．In the current society where competition is increasing，electronics professional teachers of higher vocational should enhance students’ learning and training of practical and basic skills in their teaching processes．Then，they should follow the development of electronic products pace closely，constantly adding and improving the teaching materials and the quality of electronic courses effectively．Thus，they will achieve the goal of cultivating practical and skilled expertise for the community．
