1. 研究目的与意义在日常学习生活中接触到了微电影广告，并对其逐渐产生了浓厚的兴趣。在实习的过程中，接触到越来越多该类型的广告题材，使我将之作为毕业论文的研究对象。众所周知的是，伴随着物联网技术的发展，年轻一代的时间越发碎片化。习惯快速接受信息的我们对纯文字和冗长的视频失去了耐性，我们迫切希望寻找到一种简短并且具有冲击力的短片，在满足我们视觉渴望的同时，也贴近我们的生活。于是乎，微电影应运而生，而广告行业也在微电影的助推作用下产生了微电影广告。微电影广告顺应着企业的需求，在潜移默化中给目标受众灌输品牌标志和品牌文化，提升品牌影响力。理论意义：微电影广告是新起之秀，作为新事物，学术研究相对较少，尤其是特定银行领域的研究，更是少。而一个新生事物的发展不仅需要外部环境�

1. 研究目的与意义（文献综述包含参考文献）Literaturbericht文献综述 Der Zweitspracherwerb hat eine lange Geschichte in der westlichen Welt. Die Forschung des Zweitspracherwerbs reicht in die Nachkriegszeit zur#252;ck. Im Zeitraum 1940er- 1970er spielte die behavioristische Spracherwerbstheorie eine wichtige Rolle. (Hufeisen, B. und Riemer 2010) In dieser Zeit gehorte die Theorie des Zweitspracherwerbs nur zu einem Teil der Didaktik. Eines der wichtigste Ergebnisse ist die Kontrastivhypothese. Nach dem zweiten Weltkrieg hat Lado die Kontrastivhypothese vorgebracht. Diese Hypothese stammte von der Theorie vom amerikanischen Behavioristen Skinner. Er verglich die Merkmale der unterschiedlichen Sprachen und prognostizierte den Schwerpunkt des Fremdspracherwerbs und die mouml;glichen Fehler, die die Sprachlerner machen kouml;nnen. (Lado 1957) Das heiszlig;t, man kann durch die Unterschiedlichkeit zwischen der Muttersprache und der Fremdsprache die Schwierigkeit des

1. 研究目的与意义（文献综述） Thedevelopment of new energy vehicle has became the tendency of the nowadaysautomobile industry. The traditional fossil energy is non-renewable, and itcontributes to a large number of pollution when it burnt. So energy-saving andenvironmental protection is the theme of automotive development in today’ sworld. The appearance of new energy vehicle solve these two problems. Amongthose new energy vehicle the electric vehicle(EV) is the most significant, andit has a mature technology. EV has a huge development prospect in commercialvehicle especially in engineering vehicle. So designing some reliablefunctional engineering vehicle is very meaningful. Steeringsystem is the mechanism which is used to hold or change the driving directionof vehicle. The property of steering system greatly determine a vehicle’sperformance and service life. With the advance of the automobile, peopleimprove the requirement of steering system. It should not only pr

1. 研究目的与意义（文献综述） University is an important stage for students where they step half into the community, making independent arrangements for their learning without the supervision of their parents. After the strict management in high school aiming at the specific goal- college entrance examination, this is the first time for students to re-explore the meaning of learning and to plan for the future. First of all, English as an important tool to meet the need of English Grading Test, job requirement or even postgraduate exam, is definitely a ridge which every college student should cross. Secondly, under the fact that English is a compulsory course in the university, students perceived teacher support behavior will affect their academic self-regulation of development, and will thus affect their academia performance. In addition, self-efficacy is another factor influencing self-regulated learning. Students with higher self-efficacy are more involved in lea

1. 研究目的与意义（文献综述） In the 1980s, SRAhmed proposed the famous Ahmed normalized model. And the Ahmed model was analyzed experimentally in the low speed wind tunnel. By changing the posterior inclination of the model, the model surface pressure and the six component force were studied and tail flow field were measured. The research on the thermal comfort of the car occupants is mainly aimed at the study of the velocity field and the temperature field inside the compartment under the condition of opening the air conditioner. In 1974, Nielsen in Denmark took the airflow in the ventilated room as the object of study, and simulated it with CFD technology, which had a milestone significance for CFD in the field of HVAC. GM's combination of CFD fundamentals, developed VINE3D software, the software is the first dedicated to the car thermal environment analysis of common software. In 2007, Meng Qingchao of Hunan University studied the velocity field and airflow organizati
