13.3.3 C类放大器在C类功率放大器中，栅的偏压设成使晶体管在小于一半的时间内导通。
因此，漏极电流是由周期性的一串脉冲构成的。
传统上用正弦的上面部分来近似这些脉冲以便于进行直接分析②。
特别是我们假设漏极电流具有如下的形式：式中，偏置值I DC类似于线性放大器中的偏置电流，它对于C类放大器实际上是负值。
自然，整个漏极电流i D心总是为正或为零。
也就是说，漏极电流在晶体管导通时是一段正弦波，而在晶体管截止时为零。
我们继续假设晶体管在任何时候的工作情况都像是一个电流源(高输出阻抗)③。
由于我们仍然有一个高Q值的输出振荡回路，所以在负载两端的电压基本上保持为正弦，因此漏极电压和漏极电流如图13.4所示。
在以下的推导中，不必担心能否重复所有的这些细节。
正如我们将要看到的，我们如何设计这样的放大器与这些公式本身的含义有显著的不同，所以重点要放在所得到的一般结论而不是一些具体细节上。
我们从求解漏极电流不为零时总的导通角开始。
为了简化得到这一答案所需要的步骤，我们首先用余弦而不是正弦来重新写出漏极电流的表达式：显然，这样做没有任何改变，因为时间原点总是任选的。
在经过这样的修改之后，电流脉冲就如图13．5所示。
使电流等于零并求出总的导通角2中得到：我们现在可以计算平均漏极电流为:在用I DC的表达式替换后得到:我们将很快用这个表达式来推导效率作为导通角函数的公式。
我们需要的另一个量是传送到负载的功率的一般表达式。
正如与B类放大器一样由于高Q值的振荡回路而被简化，所以我们只需要计算傅里叶级数中的基波项：利用我们通过负载的基波电流的表达式，我们可以很容易地推导出最大输出电压摆幅的公式：上式允许我们求解用V DD表示的电流irf:峰值漏极电流为irf与偏置项的和为：上式可简化为:对于固定的输出电压，当脉冲宽度减小至零时，峰值漏极电流接近无穷大。
利用我们刚刚推导的公式可以很容易地计算出漏极效率为：当导通角缩小至零时，效率接近100％。

Unit 1 Genetically modified foods -- Feed the World?If you want to spark a heated debate at a dinner party, bring up the topic of genetically modified foods. For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, health, safety and ethical questions. Particularly in countries with long agrarian traditions -- and vocal green lobbies -- the idea seems against nature.如果你想在某次晚宴上挑起一场激烈的争论，那就提出转基因食品的话题吧。
对许多人来说，高科技的转基因作物生产的概念会带来诸如环境、健康、安全和伦理等方面的各种问题。
特别是在有悠久的农业生产传统和主张环保的游说集团的国家里，转基因食品的主意似乎有悖自然。
In fact, genetically modified foods are already very much a part of our lives. A third of the corn and more than half the soybeans and cotton grown in the US last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year. The genetic is out of the bottle.事实上，转基因食品已经成为我们生活重要的一部分。

2.1 Chemistry (inorganic, organic)
Preliminary knowledge
Inorganic chemistry is a branch of chemistry concerned with the properties and reactions of inorganic compounds. Organic chemistry is the scientific study of the structure, properties, composition, and reactions of organic compounds Chemical reactions are known as chemical changes - changes in the structure of molecules-molecules attaching to each other to form larger molecules, molecules breaking apart to form two or more smaller molecules, or rearrangements of atoms within molecules. Chemical reactions usually involve the making or breaking of chemical bonds. Molecules: can be either polyatomic or monoatomic. Polyatomic molecules are electrically neutral clusters of two or more atoms joined by shared pairs of electrons (covalent bonds). A substance that is made up of molecules is called a molecular substance. Many familiar substances are made of molecules (e.g. table sugar, water, most gases) while many other equally familiar substances are not molecular in their structure (e.g. metals).

中英文文献翻译-变速器概述
附录附录A英文科技文献Transmission OverviewTransmission gearbox's function the engine's output rotational speed is high, the maximum work rate and the maximum torque appears in certain rotational speed area. In order to display engine's optimum performance, must have a set of variable speed gear, is coordinated the engine the rotational speed and wheel's actual moving velocity. The transmission gearbox may in the automobile travel process, has the different gear ratio between the engine and the wheel, through shifts gears may cause the engine work under its best power performance condition. Transmission gearbox's trend of development is more and more complex, the automaticity is also getting higher and higher, the automatic transmission will be future mainstream.Automotive Transmission's mission is to transfer power, and in the process of dynamic change in the transmission gear ratio in order to adjust or change the characteristics of the engine, at the same time through the transmission to adapt to different driving requirements. This shows that the transmission lines in the automotive transmission plays a crucial role. With the rapid development of science and technology, people's car is getting higher and higher performance requirements, vehicle performance, life, energy consumption, such as vibration and noise transmission depends largely on the performance, it is necessary to attach importance to the study of transmission.Transmission gearbox's pattern the automobile automatic transmission common to have three patterns: Respectively is hydraulic automatic transmission gearbox (AT), machinery stepless automatic transmission (CVT), electrically controlled machinery automatic transmission (AMT). At present what applies is most widespread is, AT becomes automatic transmission's pronoun nearly.AT is by the fluid strength torque converter, the planet gear and the hydraulic control system is composed, combines the way through the fluid strength transmission and the gear to realize the speed change bending moment. And the fluid strength torque converter is the most important part, it by components and so on pump pulley,turbine wheel and guide pulley is composed, has at the same time the transmission torque and the meeting and parting function.And AT compare, CVT has omitted complex and the unwieldy gear combination variable transmission, but is two groups of band pulleys carries on the variable transmission. Through changes the driving gear and the driven wheel transmission belt's contact radius carries on the speed change. Because has cancelled the gear drive, therefore its velocity ratio may change at will, the speed change is smoother, has not shifted gears kicks the feeling.AMT and the hydraulic automatic transmission gearbox (AT) is the having steps automatic transmission equally. It in the ordinary manual transmission gearbox's foundation, through installs the electrically operated installment which the microcomputer controls, the substitution originally coupling's separation which, the joint and the transmission gearbox completes by the manual control elects to keep off, to shift gears the movement, realizes fluid drive.Manual transmission gear mainly uses the principle of deceleration. Transmission within the group have different transmission ratio gear pair, and the car at the time of shift work, that is, through the manipulation of institutions so that the different transmission gear pair work. Manual transmission, also known as manual gear transmission, with axial sliding in the gears, the meshing gears through different speed to achieve the purpose of torque variation. Manual shift transmission can operate in full compliance with the will of the driver, and the simple structure, the failure rate is relatively low, value for money.Automatic transmission is based on speed and load (throttle pedal travel) for two-parameter control gear in accordance with the above two parameters to automatically take-off and landing. Automatic transmission and manual transmission in common, that is, there are two-stage transmission, automatic transmission can only speed the pace to automatically shift, manual transmission can be eliminated, "setback" of the shift feel.Automatic transmission is a torque converter, planetary gears and hydraulic manipulation of bodies, through the hydraulic transmission and gear combination to achieve the purpose of variable-speed torque variation.Also known as CVT-type continuously variable CVT. This transmission and automatic transmission gear generally the biggest difference is that it eliminates theneed of complex and cumbersome combination of variable-speed gear transmission, and only two groups to carry out variable-speed drive pulley.CVT transmission than the traditional structure of simple, smaller and it is not the number of manual gear transmission, no automatic transmission planetary gear complex group, mainly rely on the driving wheel, the driven wheel and the transmission ratio brought about by the realization of non-class change.Widely used in automotive internal combustion engine as a power source, the torque and speed range is very small, and complex conditions require the use of motor vehicles and the speed of the driving force in the considerable changes in the scope. To resolve this contradiction, in the transmission system to set up the transmission to change transmission ratio, the expansion of the driving wheel torque and speed range in order to adapt to constantly changing traffic conditions, such as start, acceleration, climbing and so on, while the engine in the most favorable conditions to work under the scope; in the same direction of rotation of the engine under the premise of the automobile can be driven back; the use of neutral, interruption of power transmission, in order to be able to start the engine, idle speed, and ease of transmission or power shift . Transmission is designed to meet the above requirements, so that the conditions in a particular vehicle stability.In addition to transmission can be used to meet certain requirements, but also to ensure that it and the car can have a good match, and can improve the car's power and economy to ensure that the engine in a favorable condition to increase the scope of the work of the use of motor vehicles life, reduce energy consumption, reduce noise, such as the use of motor vehicles.Today the world's major car companies CVT are very active in the study. The near future, with electronic control technology to further improve, electronically controlled Continuously Variable Transmission-type is expected to be a wide range of development and application.附录B文献翻译变速器概述发动机的输出转速非常高，最大功率及最大扭矩在一定的转速区出现。

附录附录A英文科技文献Disassembly Automotive OverviewCar shortly after the invention of the automobile repair and then had the industry. In order to convenient maintenance，with jack lifting machine maintenance tools to appear. The early simple columnar foundation type hydraulic lifting machine，is greatly raised than it was still early jack and the function of the test bench，this early lifting machine can rotate function in lifting the car later，rotating 360 °. Maybe you often go to a car maintenance，now still use the lift machine to provide daily vehicle maintenance service，this kind of lifting machine has largely work for 75 years.Along with the development of the car industry，simple columnar type elevator machine design，the limitation of shows up soon. If only in car around for testing maintenance work of words，the lifting machine will be enough，but this lifting machine and the central pillar of the hoist boom would hamper into the bottom of the car most area. For simple columnar type elevator machine of these limitations，engineers have put forward a lot of lifting machine design scheme and a lot of improvement work. Now，lifting machine selection scope of great，have foundation type，spots，cut the type，type of parallel four edges form，portable，simple columnar type，double column type，four-column type，driving type，contact the car battery，symmetric，the symmetric，small trip，big lift，queue，and other various type of lifting machine design. Some lifting machine may also.In the market can see different types of different size，lifting machine，there are some particularly suitable for engaged in special type of maintenance work，there are a few lifting machine for some other maintenance work.Double column spots car battery lifting machine is contact a widespread adoption of lifting machine，in recent years all new sales lifting machine，at least two-thirds are this type. This design is very popular，there are several reasons: one is the lifting machine installation quick，do not need a wide range of excavation，also do not need to enterprise's whole layout some permanent changes. 2 it is the diversity of function，a double column spots car battery lifting machine with almost all can be used for the car maintenance work.The lifting of the machine and contact the layout of cantilever pad，making maintenance technician can easily into the bottom of the car，the car in operation and maintenance. Therefore，almost all major lifting machine manufacturers to at least one type of production double column spots type elevator machine.In recent years，I had a booming industry，especially the car industry，DuoNian to cars into the ordinary families dream has become a reality. Vehicle repair industry has got to develop，all kinds of maintenance equipment needs rapid expansion. Auto lift machine is necessary maintenance，is also the most important maintenance machinery.Auto lift machine is the role of the need of repair car level to the appropriate height，so that maintenance workers in car chassis of automobile maintenance. Below Auto lift machine such as mentioned above，the main divided into pillar type and shear type two kinds，no matter which kind of，the demand from both sides to car level synchronization up，and can't happen migration. And car chassis below must be empty. To facilitate the maintenance workers homework. This requires auto lift machine lifting device must be on both sides of the separation of both sides，and rise or fall must be synchronous. Because of the weight of the car generally very big，and lift for special smoothly，so auto lift machine typically use the hydraulic drive system. Besides the requirement from a certain range from cars both sides synchronous lifting the decline and car，also requires its can make cars at any height to stop and to keep still，so that different height of the workers in maintenance，at different location can adjust height，the most convenient for repair，so hydraulic system must have positioning keep function. In addition for car weight is very big，once hydraulic system failure，lifting machine for arm in car the force of gravity will decline rapidly to pull off the maintenance workers may be the life security threats，lifting the car on and broke the danger. So in order to prevent this happens，lifting machine must have mechanical locking devices，mechanical locks were installed in by lifting cylinder piston rod and the top and lifting arm connected pin shaft on the two root jagged rack，installation of the oil cylinder to the outside of the rack is stationary. And can the pin shaft do certain Angle，to the swing of the separation of the two root rack and mesh. When lifting arm in positioning state or hydraulic system failure，hydraulic below a certain value，dynamic rack will of its own gravity and spring under the action of forces and still rack meshing，mechanical locked，increased the lifting the security of the machine.Nearly 20 years the world lifting machine industry has changed greatly.

Intelligent Power Supply英文With the rapid development of electronic technology, application field of electronic system is more and more extensive, electronic equipment, there are more and more people work with electronic equipment, life is increasingly close relationship. Any electronic equipment are inseparable from reliable power supply for power requirements, they more and more is also high. Electronic equipment miniaturized and low cost in the power of light and thin,small and efficient for development direction. The traditional transistors series adjustment manostat is continuous control linear manostat. This traditional manostat technology more mature, and there has been a large number of integrated linear manostat module, has the stable performance is good, output ripple voltage small, reliable operation, etc. But usually need are bulky and heavy industrial frequency transformer and bulk and weight are big filter.In the 1950s, NASA to miniaturization, light weight as the goal, for a rocket carrying the switch power development. In almost half a century of development process, switch power because of is small volume, light weight, high efficiency, wide range, voltage advantages in electric, control, computer, and many other areas of electronic equipment has been widely used. In the 1980s, a computer is made up of all of switch power supply, the first complete computer power generation. Throughout the 1990s, switching power supply in electronics,electrical equipment, into the rapid development. In addition, large scale integrated circuit technology, and the rapid development ofswitch power supply with a qualitative leap, raised high frequency power products of, miniaturization, modular tide.Power switch tube, PWM controller and high-frequency transformer is an indispensable part of the switch power supply.
