In order to improve the damage feature extraction effect of prefabricated residential building components and improve the structural stability of prefabricated residential components, this paper applies BIM technology to the structural feature analysis of prefabricated residential components. Moreover, this paper adopts the simple superposition method and combines the first strength theory of material mechanics to derive the formula for calculating the cracking torque of prefabricated residential building components under compound torsion. In addition, based on the variable-angle space truss model, this paper uses a simple superposition method to derive the calculation formula for the ultimate torque of composite torsion of fabricated residential building components and applies it to the BIM fabricated residential model. Finally, this paper constructs an intelligent BIM prefabricated residential building construction damage characteristic monitoring system. Through experimental research, it can be seen that the intelligent BIM prefabricated residential building construction damage feature monitoring system proposed in this paper can monitor the damage characteristics of prefabricated residential building construction and can predict the evolution of subsequent building features.

The purpose of this study was to apply goldmag immunoprobes into establishment of nanoparticles-based colorimetric assay as well as construction of immunochromatography quantitative and qualitative system by exploring point-of-care testing of syphilis with goldmag particles carrier-based immunoprobe and analysis of spatial data of Geographic Information System (GIS) platform. Goat anti-rabbit immunoglobulin G (IgG) was coupled on the surface of modified nanoparticles, taking N-(3-dimethylaminopropyl)-N'-ethyl-carbodiimide as the connector. Then the nanoparticles were used for colorimetric detection of goat-anti-rabbit IgG in liquid phase system. Based on the analysis of spatial data in GIS platform, we found the probe constructed based on MUA-Fe304/Au nanoparticles responded more sensitive to detection objects compared with the probe designed based on PAA-FeO/Au nanoparticles, and its reaction rate constant was two times that of PAA-FeO/Au nanoparticles based goldmag immunoprobe. Goldmag particles not only can be coupled with biomolecules such as antibody/antigen and glycoprotein but also possess superparamagnetism.

Under the opportunity of the government greatly promote Education information in China, guide the high education with modern educational philosophy and support it with modern information technology, Mobile learning would inevitably arouse the education sector's Attention then mobile learning will be an importance complement way to traditional education. However, there are still many difficulties in application mobile learning to high education teaching, only to break through these difficulties can mobile learning integrated into the traditional education better, so that high education more conducive to fostering high-quality personnel.Index Terms-mbile learning high education traditional education I. INTRODUCTIONThe development of Mobile learning is accompanied by communication technologies the development of computer hardware and software developed. As the mobile communications technology develops from the first generation of mobile communications technology analog mobile communication technology, the second generation of narrowband digital mobile communication technology to thirdgeneration broadband multimedia digital mobile communication technology, technologies based on mobile communication technology are richer and richer. All kinds of multimedia digital mobile communications technologies which based on broadband technology and mobile computing technology , from voice calls, text messages, multimedia messages to the WAP browser and mobile games, constantly out of the lab. Bluetooth technology, WAP technology, GPRS system, and the successful development of UMTS systems, mobile phones and mobile computing are rapidly use all over the world, launched a ideal foundation and provide a material preparation for mobile education technology. We had entered a mobile era. The applications of Mobile communication technology and mobile technology in education , gave birth to a brand new form of learning -mobile learning.
