WeChat software is an important social tool in modern society. This paper discusses the network impact of WeChat from ten aspects including WeChat popularity, attention, video observability, network reputation, function usability, dissemination speed of information, transmission ratio of positive energy and impact of WeChat on network economy, politics and culture, and questionnaires on these ten influence factors are distributed to college students for investigation. Principal component analysis is used to deal with the survey results, the principal components of the ten factors are extracted, and the results show that WeChat popularity, attention, video observability, network reputation and function usability are the main components, in which WeChat popularity, attention and video observability are the factors having the greatest impact on the calculation. And this paper presents the function relationship between the main principal components of WeChat network impact index and these ten influence factors, to evaluate the network impact index of WeChat.

This paper introduces the concept and characteristic of narrowing-mouth process, and the main technological defects and the influence factors of narrowing-mouth deformation degree. Processing technology of double closed ball head tube parts was analyzed and narrowing-mouth process was used to manufacture. On this basis, the content and steps for mouth process calculation were introduced detailed. The number of narrowing-mouth process, deformation degree of every process, the height of the blank and the size of parts were given. Meanwhile the press machine was selected. Combined with parts trial, the narrowing-mouth die structure was designed a detailed discussion of the work principle of the die, relationship and function of main parts of die were done. Through analysis of the specimen quality, the results explain that the narrowing-mouth technical calculation and die design can satisfy the processing technology of all the given parts. It can basically meet the design requirements. Finally the influence on narrowing-mouth process of neglected deformation and further research to improve it are pointed out.

By numerical simulation, the researches of effecting initial crack forming with slotted charge blasting are performed. The effecting factories conclude radial uncoupled parameter α and seam width W. Herein α adopts 1.43, 1.67 and 2, and 4, 6, 8 and 10 are adopted by W separately. The pressure peak is 15.5 GPa under α=1.67, and formed long cracks. With 6 and 8 mm seam widths, energy focus phenomenon is remarkable. The results show that initial damage of rock are decided by peak pressure of gas and function time. The seam width has significant effect to initial damage. With W adopting 6 and 8 mm, effective energy propagation is ensured and excessive damage area is avoided. The experiments validate the simulation results.
