1. 研究目的与意义（文献综述） The full name of the repair vehicle is road repair vehicle, also known as trailer, road rescue vehicle, towing vehicle, with lifting, pulling and lifting traction and other functions, the repair vehicle is mainly used for road fault vehicles, urban vehicles and illegal rescue and rescue. Road clearance and rescue technology originated from the United States, where road traffic is very developed. As early as the 1950s, the world's first repair truck was produced. This beginning marks the beginning of the development history of repair trucks.The vehicle is mainly used to remove road obstacles, clean up the accident vehicles, clean up the urban environment, and provide assistance and rescue services to drivers and vehicles.Widely used in highways, urban construction, auto repair industry, airports, ports and highway companies and other departments.It is also used for special transportation functions of "trouble-free vehicles".The first stage of t

1. 研究目的与意义（文献综述） th the development of China's highway transportation industry and the popularization of vehicles, we can now travel quickly and effectively, but the attendant problem is: traffic accidents have increased accordingly, and the size of faulty models vary, in view of this situation, road scavengers came into being. Road Scavenger means a special car with road rescue operation Equipment, referred to as a scavenger, also known as a road rescue vehicle, trailer, towing car. The scavenger is mainly composed of chassis, lifting device, lift traction device, hydraulic system, electronic control system, vehicle body and toolbox, etc. It has many functions, such as lifting, pulling and lifting traction. It is used for the clearance of highways and urban roads. As the car on the road when the fault and accident is inevitable, the main task of the clearance vehicle amount is to drag the faulty car or accident car away from the scene in time to ensure that t

1. 研究目的与意义（文献综述） 　日本において、高齢化はさらに進み、2013年には６５歳以上の高齢者人口が全人口の25％となった。日本の６５歳以上の高齢者人口の割合は世界でほぼ最高だった。中国にも同じ社会問題がある。2014年には６0歳以上の高齢者人口が２．１億、全人口の15.5％となった。高齢者の増加に伴い、高齢認知症患者の数も増加している。また、認知症は、現在にはすでに大きな社会問題になっており、今後ますます深刻になることが予想される。高齢認知症は徘徊、幻覚、物忘れ、判断力低下などの症状がある。高齢認知症は高齢者患者と患者の家族に不便をもたらすことになる。したがって、重視度を高めるはずということがわかる。 　本論では「認知症の発病原因」から、日本と中国の高齢発病率を比べて

1. 研究目的与意义（文献综述） 1.Purpose and Significance (Including domestic and foreign research statusanalysis) The rapid development ofmodern electronic information and network technology has promoted theintelligence of many industries. This wave extends to the automotive industryand various types of driverless cars have emerged. [1]。 In the past 10 years, theequipment technology of China's environmental sanitation vehicles has developedrapidly. The types and functions of the products have been able to basicallymeet the general operating requirements. With the rapid development of economyand society, the appearance of urban environmental hygiene and people’sincreasing demands on living environment quality, especially the BeijingOlympic Games and the Shanghai World Expo, the requirements for equipment andtechnology of environmental sanitation vehicles have been raised. Sanitationvehicles and equipment will be integrated, environmental-protected, humanized,and dig

1. 研究目的与意义（文献综述） This paper aims at suggesting a comparative overview of two translation strategies appeared in two Chinese editions of The Moon and Sixpence. W. Somerset Maugham, a most popular British playwright, novelist and short story writer, was endowed with great writing ability. One of his well-received masterpiece, The Moon and Sixpence, in part based on the life of the painter Paul Gauguin, explores into the mind and soul of the protagonist Charles Strickland who abandoned his family to be an artist in his middle age. This book is often mentioned by so-called "bookworms" as well as being abandoned. China has seen more and more versions in recent years, readers who are not familiar with it might have trouble to choose one to begin. Surely the first version of this book is the most classic and authoritative one, of which the translator is Fu Weici, a respectable translator, for its serious diction and relatively thorough understanding of Maugh

1. 研究目的与意义（文献综述） The purpose of this project is the rear suspension design of the Model 1070 electric truck. The significance is to study the advantages of using electric energy as an energy source on trucks and the impact on the overall layout of trucks. Using the electric vehicles have these following advantages: (1) Essentially zero emissions, in the driving process, the car uses electrical energy, no exhaust emissions, no pollution to the environment; (2) The energy efficiency of electric vehicles is higher than that of fuel vehicles; 3) Only use a single electric energy source, thus eliminating the need for engines, transmissions, fuel tanks and other systems. The structure is relatively simple; (4) The noise is relatively small; (5) The car can be charged when the electricity at the low peak and the power generation equipment fully utilized. However, electric cars also face some problems at this stage. For example, (1) the cruising range is relatively sh

1. 研究目的与意义（文献综述） 混凝土高性能化是人们一直所追求的目标，其包括新拌混凝土的工作性、硬化混凝土的力学性能和耐久性的高性能。而早期新拌混凝土的工作性影响后期强度的发展和耐久性，因此，混凝土工作性能越来越受到人们的重视。良好的工作性能是混凝土达到预定质量要求的先决条件，它不仅关系到施工质量，还影响劳动强度、施工进度，更重要是严重影响着混凝土硬化后的物理力学性能及耐久性能。 蒲心诚教授指出良好的工作性能、硬化后的较高的力学性能、良好的体积稳定性及耐久性是新拌高性能混凝土应该具备的四个方面的基本要求。在这四个性能中，良好的工作性能与另外三个方面有相互对立，混凝土的高强度、体积稳定和好的耐久性，要求较小的水灰比，较少的用水量；然而良好的工作性能，要求较大的流动�

1. 研究目的与意义（文献综述） 阻力性能是船舶快速性的主要研究内容之一，很大程度上决定了船舶的航行经济性，因此阻力性能是评价船舶型线设计优劣的主要指标之一。船舶阻力由摩擦阻力、压阻力等成分组成。一般来说，在船舶设计初始阶段，可通过模型拖拽试验的方法来确定其阻力性能，从而判断是否达到快速性的设计要求。然而，在设计初始阶段，可能会有一系列设计方案，因此采用模型试验的方法来确定所有设计船型的阻力所需费用高、准备时间长。另一方面，尽管通过模型试验能获得较可靠的船舶阻力性能曲线，但较难得到相应的阻力成分，而国际上的通用做法是采用平板摩擦阻力系数的经验公式来确定船的摩擦阻力，再将其从总阻力中扣除，确定阻力的其它成分。但是，采用经验公式计算船的摩擦阻力系数，可能会带来计算误差

1. 研究目的与意义（文献综述包含参考文献）Introduction The essence of allegory is metaphor, which is not only a rhetorical device，but also a way of thinking( Lakoff personal thoughts has the characteristic of indirect speech act, which makes them more acceptable. Allegories in the Hanfeizi are the masterpiece of all allegories in the pre-Qin period with a high artistic level and ideological value. Conceptual blending theory plays an important role in cognitive linguistics with a strong explanatory power for on-line meaning construction of natural language in Hanfeizis allegories. From the perspective of cognition, by virtue of conceptual blending theory, interpreting some prototypical instances of allegories in Hanfeizi, we find out that conceptual blending theory proves to be applicable for cognitive interpretation allegories. Modern and contemporary scholars have made comprehensive researches mainly in terms of the quantity, artistic achievements, ideological con
