齿轮和轴的介绍
摘要:在传统机械和现代机械中齿轮和轴的重要地位是不可动摇的。齿轮和轴主要安装在主轴箱来传递力的方向。通过加工制造它们可以分为许多的型号，分别用于许多的场合。所以我们对齿轮和轴的了解和认识必须是多层次多方位的。
关键词:齿轮；轴
在直齿圆柱齿轮的受力分析中，是假定各力作用在单一平面的。我们将研究作用力具有三维坐标的齿轮。因此，在斜齿轮的情况下，其齿向是不平行于回转轴线的。而在锥齿轮的情况中各回转轴线互相不平行。像我们要讨论的那样，尚有其他道理需要学习，掌握。
斜齿轮用于传递平行轴之间的运动。倾斜角度每个齿轮都一样，但一个必须右旋斜齿，而另一个必须是左旋斜齿。齿的形状是一溅开线螺旋面。如果一张被剪成平行四边形（矩形）的纸张包围在齿轮圆柱体上，纸上印出齿的角刃边就变成斜线。如果我展开这张纸，在血角刃边上的每一个点就发生一渐开线曲线。
直齿圆柱齿轮轮齿的初始接触处是跨过整个齿面而伸展开来的线。斜齿轮轮齿的初始接触是一点，当齿进入更多的啮合时，它就变成线。在直齿圆柱齿轮中，接触是平行于回转轴线的。在斜齿轮中，该先是跨过齿面的对角线。它是齿轮逐渐进行啮合并平稳的从一个齿到另一个齿传递运动，那样就使斜齿轮具有高速重载下平稳传递运动的能力。斜齿轮使轴的轴承承受径向和轴向力。当轴向推力变的大了或由于别的原因而产生某些影响时，那就可以使用人字齿轮。双斜齿轮（人字齿轮）是与反向的并排地装在同一轴上的两个斜齿轮等效。他们产生相反的轴向推力作用，这样就消除了轴向推力。当两个或更多个单向齿斜齿轮被在同一轴上时，齿轮的齿向应作选择，以便产生最小的轴向推力。
交错轴斜齿轮或螺旋齿轮，他们是轴中心线既不相交也不平行。交错轴斜齿轮的
齿彼此之间发生点接触，它随着齿轮的磨合而变成线接触。因此他们只能传递小的载荷和主要用于仪器设备中，而且肯定不能推荐在动力传动中使用。交错轴斜齿轮与斜齿轮之间在被安装后互相捏合之前是没有任何区别的。它们是以同样的方法进行制造。一对相啮合的交错轴斜齿轮通常具有同样的齿向，即左旋主动齿轮跟右旋从动齿轮相啮合。在交错轴斜齿设计中，当该齿的斜角相等时所产生滑移速度最小。然而当该齿的斜角不相等时，如果两个齿轮具有相同齿向的话，大斜角齿轮应用作主动齿轮。
蜗轮与交错轴斜齿轮相似。小齿轮即蜗杆具有较小的齿数，通常是一到四齿，由于它们完全缠绕在节圆柱上，因此它们被称为螺纹齿。与其相配的齿轮叫做蜗轮，蜗轮不是真正的斜齿轮。蜗杆和蜗轮通常是用于向垂直相交轴之间的传动提供大的角速度减速比。蜗轮不是斜齿轮，因为其齿顶面做成中凹形状以适配蜗杆曲率，目的是要形成线接触而不是点接触。然而蜗杆蜗轮传动机构中存在齿间有较大滑移速度的缺点，正像交错轴斜齿轮那样。
蜗杆蜗轮机构有单包围和双包围机构。单包围机构就是蜗轮包裹着蜗杆的一种机构。当然，如果每个构件各自局部地包围着对方的蜗轮机构就是双包围蜗轮蜗杆机构。着两者之间的重要区别是，在双包围蜗轮组的轮齿间有面接触，而在单包围的蜗轮组的轮齿间有线接触。一个装置中的蜗杆和蜗轮正像交错轴斜齿轮那样具有相同的齿向，但是其斜齿齿角的角度是极不相同的。蜗杆上的齿斜角度通常很大，而蜗轮上的则极小，因此习惯常规定蜗杆的导角，那就是蜗杆齿斜角的余角；也规定了蜗轮上的齿斜角，该两角之和就等于90度的轴线交角。
当齿轮要用来传递相交轴之间的运动时，就需要某种形式的锥齿轮。虽然锥齿轮通常制造成能构成90度轴交角，但它们也可产生任何角度的轴交角。轮齿可以铸出，铣制或滚切加工。仅就滚齿而言就可达一级精度。在典型的锥齿轮安装中，其中一个锥齿轮常常装于支承的外侧。这意味着轴的挠曲情况更加明显而使在轮齿接触上具有更大的影响。
另外一个难题，发生在难于预示锥齿轮轮齿上的应力，实际上是由于齿轮被加工成锥状造成的。
直齿锥齿轮易于设计且制造简单，如果他们安装的精密而确定，在运转中会产生良好效果。然而在直齿圆柱齿轮情况下，在节线速度较高时，他们将发出噪音。在这些情况下，螺旋锥齿轮比直齿轮能产生平稳的多的啮合作用，因此碰到高速运转的场合那是很有用的。当在汽车的各种不同用途中，有一个带偏心轴的类似锥齿轮的机构，
那是常常所希望的。这样的齿轮机构叫做准双曲面齿轮机构，因为它们的节面是双曲回转面。这种齿轮之间的轮齿作用是沿着一根直线上产生滚动与滑动相结合的运动并和蜗轮蜗杆的轮齿作用有着更多的共同之处。
轴是一种转动或静止的杆件。通常有圆形横截面。在轴上安装像齿轮，皮带轮，飞轮，曲柄，链轮和其他动力传递零件。轴能够承受弯曲，拉伸，压缩或扭转载荷，这些力相结合时，人们期望找到静强度和疲劳强度作为设计的重要依据。因为单根轴可以承受静压力，变应力和交变应力，所有的应力作用都是同时发生的。
“轴”这个词包含着多种含义，例如心轴和主轴。心轴也是轴，既可以旋转也可以静止的轴，但不承受扭转载荷。短的转动轴常常被称为主轴。
当轴的弯曲或扭转变形必需被限制于很小的范围内时，其尺寸应根据变形来确定，然后进行应力分析。因此，如若轴要做得有足够的刚度以致挠曲不太大，那么合应力符合安全要求那是完全可能的。但决不意味着设计者要保证；它们是安全的，轴几乎总是要进行计算的，知道它们是处在可以接受的允许的极限以内。因之，设计者无论何时，动力传递零件，如齿轮或皮带轮都应该设置在靠近支持轴承附近。这就减低了弯矩，因而减小变形和弯曲应力。
虽然来自M.H.G方法在设计轴中难于应用，但它可能用来准确预示实际失效。这样，它是一个检验已经设计好了的轴的或者发现具体轴在运转中发生损坏原因的好方法。进而有着大量的关于设计的问题，其中由于别的考虑例如刚度考虑，尺寸已得到较好的限制。
设计者去查找关于圆角尺寸、热处理、表面光洁度和是否要进行喷丸处理等资料，那真正的唯一的需要是实现所要求的寿命和可靠性。
由于他们的功能相似，将离合器和制动器一起处理。简化摩擦离合器或制动器的动力学表达式中，各自以角速度w1和w2运动的两个转动惯量I1和I2，在制动器情况下其中之一可能是零，由于接上离合器或制动器而最终要导致同样的速度。因为两个构件开始以不同速度运转而使打滑发生了，并且在作用过程中能量散失，结果导致温升。在分析这些装置的性能时，我们应注意到作用力，传递的扭矩，散失的能量和温升。所传递的扭矩关系到作用力，摩擦系数和离合器或制动器的几何状况。这是一个静力学问题。这个问题将必须对每个几何机构形状分别进行研究。然而温升与能量损失有关，研究温升可能与制动器或离合器的类型无关。因为几何形状的重要性是散热表面。各种各样的离合器和制动器可作如下分类：
1．轮缘式内膨胀制冻块；
2．轮缘式外接触制动块；
3．条带式；
4．盘型或轴向式；
5．圆锥型；
6．混合式。
分析摩擦离合器和制动器的各种形式都应用一般的同样的程序，下面的步骤是必需的：
1．假定或确定摩擦表面上压力分布；
2．找出最大压力和任一点处压力之间的关系；
3．应用静平衡条件去找寻（a）作用力；（b）扭矩；(c)支反力。
混合式离合器包括几个类型，例如强制接触离合器、超载释放保护离合器、超越离合器、磁液离合器等等。
强制接触离合器由一个变位杆和两个夹爪组成。各种强制接触离合器之间最大的区别与夹爪的设计有关。为了在结合过程中给变换作用予较长时间周期，夹爪可以是棘轮式的，螺旋型或齿型的。有时使用许多齿或夹爪。他们可能在圆周面上加工齿，以便他们以圆柱周向配合来结合或者在配合元件的端面上加工齿来结合。
虽然强制离合器不像摩擦接触离合器用的那么广泛，但它们确实有很重要的运用。离合器需要同步操作。
有些装置例如线性驱动装置或电机操作螺杆驱动器必须运行到一定的限度然后停顿下来。为着这些用途就需要超载释放保护离合器。这些离合器通常用弹簧加载，以使得在达到预定的力矩时释放。当到达超载点时听到的“喀嚓”声就被认定为是所希望的信号声。
超越离合器或连轴器允许机器的被动构件“空转”或“超越”，因为主动驱动件停顿了或者因为另一个动力源使被动构件增加了速度。这种离合器通常使用装在外套筒和内轴件之间的滚子或滚珠。该内轴件，在它的周边加工了数个平面。驱动作用是靠在套筒和平面之间契入的滚子来获得。因此该离合器与具有一定数量齿的棘轮棘爪机构等效。
磁液离合器或制动器相对来说是一个新的发展，它们具有两平行的磁极板。这些磁极板之间有磁粉混合物润滑。电磁线圈被装入磁路中的某处。借助激励该线圈，磁
液混合物的剪切强度可被精确的控制。这样从充分滑移到完全锁住的任何状态都可以获得。
GEAR AND SHAFT INTRODUCTION
Abstract: The important position of the wheel gear and shaft can't falter in traditional machine and modern machines.The wheel gear and shafts mainly install the direction that delivers the dint at the principal axis box.The passing to process to make them can is divided into many model numbers, useding for many situations respectively.So we must be the multilayers to the understanding of the wheel gear and shaft in many ways .
Key words:Wheel gear;Shaft
In the force analysis of spur gears, the forces are assumed to act in a single plane. We shall study gears in which the forces have three dimensions. The reason for this, in the case of helical gears, is that the teeth are not parallel to the axis of rotation. And in the case of bevel gears, the rotational axes are not parallel to each other. There are also other reasons, as we shall learn.
Helical gears are used to transmit motion between parallel shafts. The helix angle is the same on each gear, but one gear must have a right-hand helix and the other a left-hand helix. The shape of the tooth is an involute helicoid. If a piece of paper cut in the shape of a parallelogram is wrapped around a cylinder, the angular edge of the paper becomes a helix. If we unwind this paper, each point on the angular edge generates an involute curve. The surface obtained when every point on the edge generates an involute is called an involute helicoid.
The initial contact of spur-gear teeth is a line extending all the way across the face of the tooth. The initial contact of helical gear teeth is
a point, which changes into a line as the teeth come into more engagement. In spur gears the line of contact is parallel to the axis of the rotation; in helical gears, the line is diagonal across the face of the tooth. It is this gradual of the teeth and the smooth transfer of load from one tooth to another, which give helical gears the ability to transmit heavy loads at high speeds. Helical gears subject the shaft bearings to both radial and thrust loads. When the thrust loads become high or are objectionable for other reasons, it may be desirable to use double helical gears. A double helical gear (herringbone) is equivalent to two helical gears of opposite hand, mounted side by side on the same shaft. They develop opposite thrust reactions and thus cancel out the thrust load. When two or more single helical gears are mounted on the same shaft, the hand of the gears should be selected so as to produce the minimum thrust load.
Crossed-helical, or spiral, gears are those in which the shaft centerlines are neither parallel nor intersecting. The teeth of crossed-helical fears have point contact with each other, which changes to line contact as the gears wear in. For this reason they will carry out very small loads and are mainly for instrumental applications, and are definitely not recommended for use in the transmission of power. There is on difference between a crossed helical gear and a helical gear until they are mounted in mesh with each other. They are manufactured in the same way. A pair of meshed crossed helical gears usually have the same hand; that is ,a right-hand driver goes with a right-hand driven. In the design of crossed-helical gears, the minimum sliding velocity is obtained when the helix angle are equal. However, when the helix angle are not equal, the gear with the larger helix angle should be used as the driver if both gears have the same hand.
Worm gears are similar to crossed helical gears. The pinion or worm has a small number of teeth, usually one to four, and since they completely wrap around the pitch cylinder they are called threads. Its mating gear is called a worm gear, which is not a true helical gear. A worm and worm gear are used
to provide a high angular-velocity reduction between nonintersecting shafts which are usually at right angle. The worm gear is not a helical gear because its face is made concave to fit the curvature of the worm in order to provide line contact instead of point contact. However, a disadvantage of worm gearing is the high sliding velocities across the teeth, the same as with crossed helical gears.
Worm gearing are either single or double enveloping. A single-enveloping gearing is one in which the gear wraps around or partially encloses the worm..
A gearing in which each element partially encloses the other is, of course, a double-enveloping worm gearing. The important difference between the two is that area contact exists between the teeth of double-enveloping gears while only line contact between those of single-enveloping gears. The worm and worm gear of a set have the same hand of helix as for crossed helical gears, but the helix angles are usually quite different. The helix angle on the worm is generally quite large, and that on the gear very small. Because of this, it is usual to specify the lead angle on the worm, which is the complement of the worm helix angle, and the helix angle on the gear; the two angles are equal for a 90-deg. Shaft angle.
When gears are to be used to transmit motion between intersecting shaft, some of bevel gear is required. Although bevel gear are usually made for a shaft angle of 90 deg. They may be produced for almost any shaft angle. The teeth may be cast, milled, or generated. Only the generated teeth may be classed as accurate. In a typical bevel gear mounting, one of the gear is often mounted outboard of the bearing. This means that shaft deflection can be more pronounced and have a greater effect on the contact of teeth. Another difficulty, which occurs in predicting the stress in bevel-gear teeth, is the fact the teeth are tapered.
Straight bevel gears are easy to design and simple to manufacture and give very good results in service if they are mounted accurately and positively. As in the case of squr gears, however, they become noisy at higher values of
the pitch-line velocity. In these cases it is often good design practice to go to the spiral bevel gear, which is the bevel counterpart of the helical gear. As in the case of helical gears, spiral bevel gears give a much smoother tooth action than straight bevel gears, and hence are useful where high speed are encountered.
It is frequently desirable, as in the case of automotive differential applications, to have gearing similar to bevel gears but with the shaft offset. Such gears are called hypoid gears because their pitch surfaces are hyperboloids of revolution. The tooth action between such gears is a combination of rolling and sliding along a straight line and has much in common with that of worm gears.
A shaft is a rotating or stationary member, usually of circular cross section, having mounted upon it such elementsas gears, pulleys, flywheels, cranks, sprockets, and other power-transmission elements. Shaft may be subjected to bending, tension, compression, or torsional loads, acting singly or in combination with one another. When they are combined, one may expect to find both static and fatigue strength to be important design considerations, since a single shaft may be subjected to static stresses, completely reversed, and repeated stresses, all acting at the same time.
The word “shaft”covers numerous variations, such as axles and spindles. Anaxle is a shaft, wither stationary or rotating, nor subjected to torsion load. A shirt rotating shaft is often called a spindle.
When either the lateral or the torsional deflection of a shaft must be held to close limits, the shaft must be sized on the basis of deflection before analyzing the stresses. The reason for this is that, if the shaft is made stiff enough so that the deflection is not too large, it is probable that the resulting stresses will be safe. But by no means should the designer assume that they are safe; it is almost always necessary to calculate them so that he knows they are within acceptable limits. Whenever possible, the power-transmission elements, such as gears or pullets, should be located close
to the supporting bearings, This reduces the bending moment, and hence the deflection and bending stress.
Although the von Mises-Hencky-Goodman method is difficult to use in design of shaft, it probably comes closest to predicting actual failure. Thus it is a good way of checking a shaft that has already been designed or of discovering why a particular shaft has failed in service. Furthermore, there are a considerable number of shaft-design problems in which the dimension are pretty well limited by other considerations, such as rigidity, and it is only necessary for the designer to discover something about the fillet sizes, heat-treatment, and surface finish and whether or not shot peening is necessary in order to achieve the required life and reliability.
Because of the similarity of their functions, clutches and brakes are treated together. In a simplified dynamic representation of a friction clutch, or brake, two inertias I1 and I2 traveling at the respective angular velocities W1 and W2, one of which may be zero in the case of brake, are to be brought to the same speed by engaging the clutch or brake. Slippage occurs because the two elements are running at different speeds and energy is dissipated during actuation, resulting in a temperature rise. In analyzing the performance of these devices we shall be interested in the actuating force, the torque transmitted, the energy loss and the temperature rise. The torque transmitted is related to the actuating force, the coefficient of friction, and the geometry of the clutch or brake. This is problem in static, which will have to be studied separately for eath geometric configuration. However, temperature rise is related to energy loss and can be studied without regard to the type of brake or clutch because the geometry of interest is the heat-dissipating surfaces. The various types of clutches and brakes may be classified as fllows:
1.Rim type with internally expanding shoes
2.Rim type with externally contracting shoes
3.Band type

Interaction design Moggridge Bill Interaction design，Page 1-15 USA Art Press, 2008 Interaction design (IxD) is the study of devices with which a user can interact, in particular computer users. The practice typically centers on "embedding information technology into the ambient social complexities of the physical world."[1] It can also apply to other types of non-electronic products and services, and even organizations. Interaction design defines the behavior (the "interaction") of an artifact or system in response to its users. Malcolm McCullough has written, "As a consequence of pervasive computing, interaction design is poised to become one of the main liberal arts of the twenty-first century." Certain basic principles of cognitive psychology provide grounding for interaction design. These include mental models, mapping, interface metaphors, and affordances. Many of these are laid out in Donald Norman's influential book The Psychology of Everyday Things. As technologies are often overly complex for their intended target audience, interaction design aims to minimize the learning curve and to increase accuracy and efficiency of a task without diminishing usefulness. The objective is to reduce frustration and increase user productivity and satisfaction. Interaction design attempts to improve the usability and experience of the product, by first researching and understanding certain users' needs and then designing to meet and exceed them. (Figuring out who needs to use it, and how those people would like to use it.) Only by involving users who will use a product or system on a regular basis will designers be able to properly tailor and maximize usability. Involving real users, designers gain the ability to better understand user goals and experiences. (see also: User-centered design) There are also positive side effects which include enhanced system capability awareness and user ownership. It is important that the user be aware of system capabilities from an early stage so that expectations regarding functionality are both realistic and properly understood. Also, users who have been active participants in a product's development are more likely to feel a sense of ownership, thus increasing overall satisfa. Instructional design is a goal-oriented, user-centric approach to creating training and education software or written materials. Interaction design and instructional design both rely on cognitive psychology theories to focus on how users will interact with software. They both take an in-depth approach to analyzing the user's needs and goals. A needs analysis is often performed in both disciplines. Both, approach the design from the user's perspective. Both, involve gathering feedback from users, and making revisions until the product or service has been found to be effective. (Summative / formative evaluations) In many ways, instructional

剃须心得：有钱不必花在刀刃上 A Penny Shaved Is A Penny Earned For years, I've felt like a sap whenever I bought razors. 很多年来，每当我买剃须刀时都觉得自己像个傻瓜。 It killed me to spend $2.50 to $3 a blade for my Gillette Mach 3. Yet the few times when I used cheap disposable razors, it was like shaving with a file. 为我的吉列锋速3（Gillette Mach 3）买一个刀片要花2.50美元到3美元，这让我心疼不已。但有几次我用便宜的一次性剃须刀时，感觉就像在用锉刀刮胡子。 Finally, a couple of weeks ago, I bought a serviceable store-brand razor that costs about half the price of the premier brands. Jon Protas for The Wall Street Journal 吉列锋速3是好剃须刀，但刀片的价钱真不便宜最终，几星期前，我买了一把商店自有品牌的剃须刀，这把剃须刀也还好用，而且价格只有名牌剃须刀的一半左右。 It shouldn't have come to this. I've used Gillette razors for decades, and I like them. The rub is the cost.

I was newly arrived at Apple, still learning the ways of business, when I was visited by a member of Apple's Industrial Design team. He showed me a foam mockup of a proposed product. "Wow," I said, "I want one! What is it?" That experience brought home the power of design: I was excited and enthusiastic even before I knew what it was. This type of visceral "wow" response requires creative designers. It is subjective, personal. Uh oh, this is not what engineers like to hear. If you can't put a number to it, it's not important. As a result, there is a trend to eliminate designers. Who needs them when we can simply test our way to success? The excitement of powerful, captivating design is defined as irrelevant. Worse, the nature of design is in danger. Don't believe me? Consider Google. In a well-publicized move, a senior designer at Google recently quit, stating that Google had no interest in or understanding of design. Google, it seems, relies primarily upon test results, not human skill or judgment. Want to know whether a design is effective? Try it out. Google can quickly submit samples to millions of people in well-controlled trials, pitting one design against another, selecting the winner based upon number of clicks, or sales, or whatever objective measure they wish. Which color of blue is best? Test. Item placement? Test. Web page layout? Test. This procedure is hardly unique to Google. https://www.360docs.net/doc/c82122359.html, has long followed this practice. Years ago I was proudly informed that they no longer have debates about which design is best: they simply test them and use the data to decide. And this, of course, is the approach used by the human-centered iterative design approach: prototype, test, revise. Is this the future of design? Certainly there are many who believe so. This is a hot topic on the talk and seminar circuit. After all, the proponents ask reasonably, who could object to making decisions based upon data? Two Types of Innovation: Incremental Improvements and New Concepts In design—and almost all innovation, for that matter—there are at least two distinct forms. One is

艺术装饰风格 被宣告是“唯一一个总体设计”，艺术装饰必然是在众多消费者中间找到观众的最高产的设计之一。虽然它起源于19世纪20年代高度专有的法国手工裁剪装潢艺术，但它通过利用廉价的新金属材料，塑料和玻璃而发展迅速，找到了便宜，短期利用，并可以大批生产的装饰用品，如香烟盒，香水瓶，家庭用的陶瓷和玻璃，流行纺织品及各种装饰物，还有可以像鸡尾般甩动的物品。作为一种装饰风格它可以运用于无数物品的形状和表面装饰，因而赋予它们全部以相同质量的瞬间的现代性和时尚性。 就像许多这个世纪其它的流行风格一样，艺术装饰风格扎根于高雅文化，例如，立体主义、俄国芭蕾、美洲印第安风格和欧洲纯粹主义，但是相对其他文化而言，艺术装饰风格取长补短，装饰特征表现得更为折衷一些。结合艺术装饰风格在1930年代流行的因素，大规模批量生产使用新材料是商品价格相对低廉的必要条件。但这些是远远不够的，更深层次的原因是艺术装饰风格具有典型的适应性。在那段经济萧条的时期，豪华奢侈的装饰风格所带来的美感让当时的消费者有了逃避现实的放松心情。艺术装饰风格的宣传方式也促进了它的流行，艺术风格被好莱坞应用于多种流行电影中。通过影片媒体使大量观众接触到装饰风格，除此之外，艺术装饰风格也运用在广告和包装上，使其有效的影响了大量的环境之外，艺术装饰风格也影响到了建筑领域，许多新场所也运用了这种风格，美化建筑的外表，那些新商业的
娱乐楼房，例如商场电影院，工厂，甚至于新的豪华游轮，它也被利用于在1933年芝加哥展览之中。艺术装饰风格开始象征着高效率的现代化生活和新的生活理念，这种动人的方式随着人们对时尚性和社会地位的追求与渴望，艺术装饰风格得到了大量消费者的高度喜爱地位。 艺术装饰的大量应用伴随着消费产品的需求。但是，从不好的方而来看，艺术装饰风格只是作为一种中档的艺术手法，来装饰非常廉价的商品甚至留有一种杂乱的感觉。在英国有一群针对低端市场开发产品的地毯制造商，他们意识到了这个新潮流里的商业潜力。 但是，这些地毯制造商也很注意他们消费群里的保守心理，因此，即使是在一块地毯里的花紋也会出现那些很传统的1案象是老式的叶子造型和较灰暗的颜色。这种设计的消费市场不同于那些要不就是现代型或是完全传统的设计方案。1920年代到30年代，英国都铎王室的一些新居住者和新建筑的到来，使工艺美术运动和现代风格可以较为自由的发展和合理的被采用.这些各异的艺术风格也被按照使用者的喜好不同加入到地毯的设计之中。在20世纪30年代的中期，改良过的艺术装饰风格在数不清的家居装饰里都可以看到"在花园门饰上，无线电机的面板装饰上，阿芝台克寺庙的壁炉上和那些扶手椅和沙发的几何形体上。"

1.Creative China must find its ownPath 网站截图： https://www.360docs.net/doc/c82122359.html,/baidu?word=%B9%A4%D2%B5%C9%E8%BC%C6%D3%A2%CE%C4 %CE%C4%CF%D7&tn=sogouie_1_dg 原文： Creative China must find its own Path Justin 0'Connor It is commonly said that China needs to ‘catch-up’ with `the west' or the `developed world'. This phrase implies a singular path; there may be short cuts and `late-comer advantages' but the destination一a modern, developed country一is the same. But just when it seems China is within touching distance, the `developed world' changes the definition of what it is to be `developed' and puts more obstacles in the path of those trying to catch-up. In English we call this `moving the goal-posts'. After manufacturing, services and high-technology seemed to present clear goals for China, the cultural creative industries arrive as the new `value-added' product and service sector, posing yet more problems for the country's policy-makers. Many in the West have argued that China will take a long time to catch-up in these areas and that this provides a new source of competitive advantage to the West. Indeed, for some, the absence of a competitive cultural creative industries sector is evidence that China is not, and maybe can never be, fully `developed'. Much of this can be dismissed as another example of the West's superiority complex; however, there can be no doubt that the cultural creative industries present great possibilities but also great challenges for China. These industries一from visual and performing arts, to recorded music, film and TV, to digital animation and new media services, through to fashion, design and architecture一are highly creative and innovative products and services, relying on complex flows of knowledge and intellectual property. They are also cultural or symbolic products that reflect and influence our pleasures and ambitions, and our individual and collective sense of meaning and identity. For these reasons all nations have sought to protect and develop their own national culture and traditions by investing in cultural infrastructure and expertise. In the second half of the twentieth century this was expanded beyond `the arts，一galleries,

中国经济犯罪刑事政策的转型与应然选择【摘要】刑事政策是一国犯罪状况与国家治理政策的集中反映，对一国经济社会发展具有导向作用。新中国成立以来中国经济犯罪刑事政策经历了1980年代和当前两次转型。1980年代，因经济犯罪猖獗引发经济犯罪刑事政策向“严打”政策转型，单极化成为这一政策的核心。经济转型步入深化期后，经济秩序维护与治理的内在矛盾日趋复杂、尖锐，中国经济犯罪刑事政策面临第二次转型与选择。这次转型与选择必须以宽严相济刑事政策为导向，体现“两极化”刑事政策的要求；对经济犯罪作“经济安全型”与“秩序危害型”的区分，并将仅具行为类型典型性但触犯公共安全的经济犯罪逐出既有经济犯罪的范围；合理调节犯罪圈、刑罚圈以及罪刑配置关系，实现国家有限刑法与刑罚资源的科学配置。 【关键词】犯罪治理；经济犯罪；刑事政策；转型与选择 The Transformation and Rational Selection of the Criminal Policy against Economic Crimes in China Abstract: Keywords:
现代社会以来，经济安全日益成为国家安全之重要基础，经济犯罪治理在现代国家犯罪治理中的重要地位也由此得以显现。经济犯罪的衍生与高发，是传统社会向现代社会转型的重要标志之一，经济犯罪发案率的攀升、种类的增加、领域的扩大，对一国经济安全威胁的日益加剧，是引发包括刑法在内的一国法律体系完善的重要动因之一。……进入21世纪，中国大力倡导社会主义和谐社会的构建，内在地要求中国经济犯罪刑事政策的相应调整。中国应如何确立科学的经济犯罪刑事政策，成为转型深化期以来中国刑事立法发展中亟待解决的现实问题。 一、中国经济犯罪的衍生与治理特征 （一）中国经济犯罪的衍生 1．计划体制下的经济犯罪 经济犯罪为人类所关注的历史不长。学说史的研究表明，“经济犯罪”一词最早由英国学者希尔于1872年提出。济犯罪不断扩张与膨胀，愈来愈呈现出复杂的态势。①中国自改革开放以来实行的“严打”的经济犯罪刑事政策，虽然在短时间内实现了经济犯罪率的下降和社会治安的好转，但是从长远来看，刑事立法和司法活动并未收到显著的遏制经济犯罪的效果。②进入21世纪，中国大力倡导建立社会主义和谐社会，③内在地要求中国的经济犯罪刑事政策作出相应的调整，④基于经济犯罪刑事政策对经济法治建设的重要指导性作用，⑤中国经济犯罪刑事政策必须要审时度势，作出相应改变。⑥笔者认为，⑦现代风险社会下经济犯罪的类型划分，以及与世界“轻轻重重”的经济犯罪刑事政策相呼应，中国应倡导宽严相济“两极化”的刑事政策：首先，对严重危害国家经济安全的犯罪应严，具体包括：立足本国实际，统一立法模式；严密法网；调整刑罚结构，合理配置刑罚；犯罪评价模式广泛引入行为本位主义，实现法益保护的前置化。其次，对单纯危害经济交易秩序的行为应宽，具体措施包括：完善前置性法律，加强与经济刑法的衔接；建立有效的出罪机制，坚持前置性法律用尽原则；以行政处罚等非刑罚 ①刘国钧，张敏强.教育测量学[M].北京：人民教育出版社，1998:77. ②叶澜.中国教育学发展世纪问题的审视[J].新华文摘,2004(6):76-77. ③仲伟志.2005中国改革交锋录[N].经济观察报,2005,10(3):7. ④Basar，T..Dynamic Noncooperative Game Theory[M].New York,Academic Press，1982:p.123. ⑤姚伯元．毕业设计(论文)规范化管理与培养学生综合素质［EB/OL］．：中国高等教育网教学研究，2005-2-2：12 ⑥张和生．地质力学系统理论［Ｄ］．太原：太原理工大学，1998：132 ⑦
