Aiming at solving the problem of forecasting the dynamics of express delivering quality elements classification, the paper proposed a novel method integrating Kano model with GM(1,1) model which is effective to perform fitting prediction. An approach of fuzzy questionnaires to modify Kano questionnaires which considered as subjective is suggested, and the GM (1,1) model is used to estimate and predict data according to the quality classification of fuzzy Kano model. An empirical study in express industry is provided to testify its feasibility and validity.

Abstract. Cold metal transfer (CMT) process is a modified inert gas metal welding process,which characterizes of low heat input and no spatter welding comparing with traditional GMAW process.In this paper,research of the CMT welding features of stainless steel sheet has been conducted.The effects of welding parameters including wire feed rate,welding speed and arc-length modification coefficient on mechanical properties and surface morphology were investigated.In addition,optical micrograph(OM) and scanning electron microscope(SEM) were used to analyze the weld microstructure,and microstructural characteristics were discussed as well.In the end,the optimum welding parameters which were used in real production and achieved good effect were obtained by means of orthogonal experiment.

The traditional thermal control system of the space optical remote sensor is mainly based on passive thermal control and supplemented by active thermal control of electric heater. But with the development of the remote sensor in the direction of multi-task and multi-function, the thermal control system needs to meet the requirements of low thermal control resource consumption under the condition of multi heat source and large heat load, and high adaptability under the condition of multi attitude complex orbit. The traditional thermal control system can not satisfy these new requirements. In this paper, a new adaptive thermal control system is studied. A geostationary orbit camera as an example is taken to compare the design scheme of the traditional thermal control system and the new thermal control system. The simulation results show that the new thermal control has the advantages of more optimized system resources and stronger temperature adaptability under complex tasks, which provides a new idea for the subsequent thermal control design of complex large space optical remote sensor.

Unlike the previous two translation waves in the history of China, the third translation wave beginning from LateQing period can be seen as a cross-cultural communication under confrontation and conflict between China andwestern powers. Missionaries and government officials from western powers, institutions affiliated to government,and social activists were actively engaged in various translation activities for their respective purposes by means ofcooperation, which had not only promoted western learning in China and facilitated Chinese social movements andreform, but finally brought the Qing Dynasty to an end in the Chinese Revolution of 1911. This paper aims toexplore the facilitating role of translation in social movements and reforms in China during the time of the Late QingDynasty from Skopos Theory Perspective, in order to show that translators as social activists can not only promoteintercultural communication, but also push forward social changes and help nation building. This translation wave ischaracterized by urgency, purposefulness and practicality, and played the role of enlightening people, spreadingwestern learning and facilitating revolution.
