中英文翻译中英文翻译精选推荐花旗测试扫描视网膜取款技术Citigroup is testing new technology that will allow customers to withdraw money using retinal scanning.花旗银行(Citigroup)正在测试允许客户通过扫描视网膜取款的新技术。
The bank wants to replace PIN codes with biometric scanners that could identify customers using only their eyes.花旗银行打算用仅通过客户的眼睛即可识别其身份的生物识别扫描仪来取代个人识别号码。
Customers would use a smartphone app to key in the amount they want to draw out ahead of time.客户只需在智能手机客户端上提前输入他们想取出的金额就可以了。
As they approached the ATM, the app would link up to the machine and use retinal scanning to confirm the customer’s identity.当客户走近自动取款机时，该客户端将与自动取款机连接，并通过扫描视网膜确认其身份。
The ATM would then release the cash, providing the scanner recognises the individual.若扫描仪识别出客户的身份，自动取款机就会吐出现金。
Citigroup said the retinal scans would take 15 seconds to complete compared to 45 seconds for traditional transactions.花旗银行表示，传统交易方式需花费45秒，而视网膜扫描技术可在15秒内完成交易。

中英文对照翻译Unit 1A Y oung Boy‟s AmbitionOnce a day a cheap, gaudy packet arrived upward from St. Louis, and another downward from Keokuk. Before these events, the day was glorious with expectancy; after them, the day was a dead and empty thing. Not only the boys, but the whole village, felt this. After all these years I can picture that old time to myself now, just as it was then: the white town drowsing in the sunshine of a summer's morning; the streets empty, or prettynearly so; one or two clerks sitting in front of the Water Street stores, with their splint-bottomed chairs tilted back against the wall, chins on breasts, hats slouched over their faces, asleep - with shingle-shavings enough around to show what broke them down; a sow and a litter of pigs loafing along the sidewalk, doing a good business in watermelon rinds and seeds; two or three lonely little freight piles scattered about the "levee"; a pile of "skids" on the slope of the stone-paved wharf, and the fragrant town drunkard asleep in the shadow of them; two or three wood flats at the head of the wharf, but nobody to listen to the peaceful lapping of the wavelets against them; the great Mississippi, the majestic, the magnificent Mississippi, rolling its mile-wide tide along, shining in the sun; the dense forest away on the other side; the "point" above the town, and the "point" below, bounding theriver-glimpse and turning it into a sort of sea, and withal a very still and brilliant and lonely one. Presently a film of dark smoke appears above one of those remote "points"; instantly a negro drayman, famous for his quick eye and prodigious voice, lifts up the cry, "S-t-e-a-m-boat a-comin!" and the scene changes! The town drunkard stirs, the clerks wake up, a furious clatter of drays follows, every house and store pours out a human contribution, and all in a twinkling the dead town is alive and moving.一艘简陋而外表华丽的定班轮船从圣路易斯开上来，另一艘从奇阿库克往下游开，每天都要来到这里一次。

智能开关电源中文：随着电子技术的高速发展，电子系统的应用领域越来越广泛，电子设备的种类也越来越多，电子设备与人们的工作、生活的关系日益密切。
任何电子设备都离不开可靠的电源，它们对电源的要求也越来越高。
电子设备的小型化和低成本化使电源以轻、薄、小和高效率为发展方向。
传统的晶体管串联调整稳压电源是连续控制的线性稳压电源。
这种传统稳压电源技术比较成熟，并且已有大量集成化的线性稳压电源模块，具有稳定性能好、输出波纹电压小、使用可靠等优点。
但通常都需要体积大且笨重的工频变压器与体积和重量都很大的滤波器。
二十世纪五十年代，美国宇航局以小型化、重量轻为目标，为搭载火箭开发了开关电源。
在近半个世纪的发展过程中，开关电源因具有重量轻、体积小、效率高、稳压范围宽等优点，在电子电气、控制、计算机等许多领域的电子设备中得到了广泛的使用。
二十世纪八十年代，计算机全面实现了开关电源化，率先完成计算机的电源换代。
二十世纪九十年代，开关电源在电子、电器设备、家电领域得到了广泛的应用，开关电源技术进入快速发展期。
此外，大规模集成电路技术的迅速发展，又使开关电源有了质的飞跃，掀起了电源产品高频化、小型化、模块化的浪潮。
功率开关管、PWM控制器和高频变压器是开关电源必不可少的组成部分。
传统的开关电源一般均采用分立的高频功率开关管和多引脚的PWM集成控制器，例如采用UC3842+MOSFET是国内小功率开关电源中较为普及的设计方法。
七十年代以来，涌现出许多功能完备的集成控制电路，使开关电源电路日益简化，工作频率不断提高，效率提高，并为电源小型化提供了广阔的前景。
三端离线式脉宽调制单片开关集成电路TOP(Three Terminal Off Line)将PWM控制器与功率开关MOSFET合二为一封装在一起，已成为开关电源IC发展的主流。
采用TOP开关集成电路设计开关电源，可使电路简化，体积进一步缩小，成本也明显降低。
单片开关电源具有单片集成化、最简外围电路、最佳性能指标、能构成无工频变压器开关电源等显著优点。
美国PI(Power Integration)公司于上世纪九十年代中期率先推出的新型高频开关电源芯片，被誉为"顶级开关电源"，具有成本低，电路简单，效率高等优点。
其第一代产品以1994年推出的TOP100/200系列为代表，第二代产品则是1997年问世的TOPSwitch-Ⅱ。
上述产品一经问世便显示出强大的生命力，他极大地简化了150W以下开关电源的设计和新产品的开发工作，也为新型、高效、低成本开关电源的推广与普及创造了良好条件，可广泛用于仪器仪表、笔记本电脑、移动电话、电视机、VCD和DVD、摄录像机、手机电池充电器、功率放大器等领域，并构成各种小型化、高密度、在价格上能与线性稳压电源相竞争的AC/DC电源变换模块。
开关电源向集成化方向发展将是未来的主要趋势,功率密度将越来越大,对工艺的要求也会越来越高.在半导体器件和磁性材料没有新的突破之前,重大的技术进展可能很难实现,技术创新的重点将集中在如何提高效率和减小重量.因此,工艺水平将会在电源制造中占的地位越来越高.另外,数字控制集成电路的应用也是将来开关电源发展的一个方向.这信赖于DSP运行速度和抗干扰技术的不断提高.至于先进的控制方法,目前个人觉得还没有看到实用性特别强的方法出现,也许随着数字控制的普及,会有一些新的控制理论运用到开关电源中来.（1）高频化技术：随着开关频率的提高，开关变换器的体积也随之减少，功率密度也得到大幅提升，动态响应得到改善。
小功率DC-DC变换器的开关频率将上升到MHz。
但随着开关频率的不断提高，开关元件和无源元件损耗的增加、高频寄生参数以及高频EMI等新的问题也将随之产生。
（2）软开关技术：为提高变换器的变换效率，各种软开关技术应用而生，具有代表性的是无源软开关技术和有源软开关技术，主要包括零电压开关/零电流开关（ZVS/ZCS）谐振、准谐振、零电压/零电流脉宽调制技术（ZVS/ZCS-PWM）以及零电压过渡/零电流过渡脉宽调制（ZVT/ZCT-PWM）技术等。
采用软开关技术可以有效的降低开关损耗和开关应力，有助于变换器变换效率的提高。
（3）功率因数校正技术（PFC）。
目前PFC技术主要分为有源PFC技术和无源PFC技术两大类，采用PFC技术可以提高AC-DC变化器输入端功率因数，减少对电网的谐波污染。
（4）模块化技术。
采用模块化技术可以满足分布式电源系统的需要，提高系统的可靠性。
（5）低输出电压技术。
随着半导体制造技术的不断发展，微处理器和便携式电子设备的工作越来越低，这就要求未来的DC-DC变换器能够提供低输出电压以适应微处理器和便携式电子设备的供电要求。
人们在开关电源技术领域是边开发相关电力电子器件，边开发开关变频技术，两者相互促进推动着开关电源每年以超过两位数字的增长率向着轻、小、薄、低噪声、高可靠、抗干扰的方向发展。
开关电源可分为AC/DC和DC/DC两大类，也有AC/AC DC/AC 如逆变器 DC/DC变换器现已实现模块化，且设计技术及生产工艺在国内外均已成熟和标准化，并已得到用户的认可，但AC/DC的模块化，因其自身的特性使得在模块化的进程中，遇到较为复杂的技术和工艺制造问题。
以下分别对两类开关电源的结构和特性作以阐述。
开关电源的发展方向是高频、高可靠、低耗、低噪声、抗干扰和模块化。
由于开关电源轻、小、薄的关键技术是高频化，因此国外各大开关电源制造商都致力于同步开发新型高智能化的元器件，特别是改善二次整流器件的损耗，并在功率铁氧体（Mn?Zn)材料上加大科技创新，以提高在高频率和较大磁通密度（Bs)下获得高的磁性能，而电容器的小型化也是一项关键技术。
SMT技术的应用使得开关电源取得了长足的进展，在电路板两面布置元器件，以确保开关电源的轻、小、薄。
开关电源的高频化就必然对传统的PWM开关技术进行创新，实现ZVS、ZCS的软开关技术已成为开关电源的主流技术，并大幅提高了开关电源的工作效率。
对于高可靠性指标，美国的开关电源生产商通过降低运行电流，降低结温等措施以减少器件的应力，使得产品的可靠性大大提高。
模块化是开关电源发展的总体趋势，可以采用模块化电源组成分布式电源系统，可以设计成N＋1冗余系统，并实现并联方式的容量扩展。
针对开关电源运行噪声大这一缺点，若单独追求高频化其噪声也必将随着增大，而采用部分谐振转换电路技术，在理论上即可实现高频化又可降低噪声，但部分谐振转换技术的实际应用仍存在着技术问题，故仍需在这一领域开展大量的工作，以使得该项技术得以实用化。
电力电子技术的不断创新，使开关电源产业有着广阔的发展前景。
要加快我国开关电源产业的发展速度，就必须走技术创新之路，走出有中国特色的产学研联合发展之路，为我国民经济的高速发展做出贡献。
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 its 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, acomputer 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, home appliances areas to be widely, switch power technology into the rapid development. In addition, large scale integrated circuit technology, and the rapid development of switch 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. The traditional switch power supply is normally made by using high frequency power switch tube division and the pins, such as using PWM integrated controller UC3842 + MOSFET is domestic small power switch power supply, the design method of a more popularity.Since the 1970s, emerged in many function complete integrated control circuit, switch power supply circuit increasingly simplified, working frequency enhances unceasingly, improving efficiency, and for power miniaturization provides the broad prospect. Three end off-line pulse width modulation monolithic integrated circuit TOP (Three switch Line) will Terminal Off with power switch MOSFET PWM controller one package together,has become the mainstream of switch power IC development. Adopt TOP switch IC design switch power, can make the circuit simplified, volume further narrowing, cost also is decreased obviouslyMonolithic switching power supply has the monolithic integrated, the minimalist peripheral circuit, best performance index, no work frequency transformer can constitute a significant advantage switching power supply, etc. American PI (with) company in Power in the mid 1990s first launched the new high frequency switching Power supply chip, known as the "top switch Power", with low cost, simple circuit, higher efficiency. The first generation of products launched in 1994 representedTOP100/200 series, the second generation product is the TOPSwitch - debuted in 1997 Ⅱ. The above products once appeared showed strong vitality and he greatly simplifies the design of 150W following switching power supply and the development of new products for the new job, also, high efficiency and low cost switch power supply promotion and popularization created good condition, which can be widely used in instrumentation, notebook computers, mobile phones, TV, VCD and DVD, perturbation VCR, mobile phone battery chargers, power amplifier and other fields, and form various miniaturization,density, on price can compete with the linear manostat AC/DC power transformation module.Switching power supply to integrated direction of future development will be the main trend, power density will more and more big, to process requirements will increasingly high. In semiconductor devices and magnetic materials, no new breakthrough technology progress before major might find it hard to achieve, technology innovation will focus on how to improve the efficiency and focus on reducing weight. Therefore, craft level will be in the position of power supply manufacturing higher in. In addition, the application of digital control IC is the future direction of the development of a switch power. This trust in DSP for speed and anti-interference technology unceasing enhancement. As for advanced control method, now the individual feels haven't seen practicability of the method appears particularly strong, perhaps with the popularity of digital control, and there are some new control theory into switching power supply.（1）The technology: with high frequency switching frequencies increase, switch converter volume also decrease, power density has also been boosted, dynamic response improved. Small power DC - DC converter switch frequency will rise to MHz. But as the switch frequency unceasingenhancement, switch components and passive components loss increases, high-frequency parasitic parameters andhigh-frequency EMI and so on the new issues will also be caused.（2）Soft switching technologies: in order to improve the efficiency of non-linearity of various soft switch, commutation technical application and hygiene, representative of soft switch technology is passive and active soft switch technology, mainly including zero voltage switch/zero current switch (ZVS/ZCS) resonance, quasi resonant, zero voltage/zero current pulse width modulation technology (ZVS/ZCS - PWM) and zero voltage transition/zero current transition pulse width modulation (PWM) ZVT/ZCT - technical, etc. By means of soft switch technology can effectively reduce switch loss and switch stress, help converter transformation efficiency（3）Power factor correction technology (IC simplifies PFC). At present mainly divided into IC simplifies PFC technology passive and active IC simplifies PFC technology using IC simplifies PFC technology two kinds big, IC simplifies PFC technology can improve AC - DC change device input power factor, reduce the harmonic pollution of power grid.（4）Modular technology. Modular technology can meet the needs of the distributed power system, enhance the system reliability.（5）Low output voltage technology. With the continuous development of semiconductor manufacturing technology, microprocessor and portable electronic devices work more and more low, this requires future DC - DC converter can provide low output voltage to adapt microprocessor and power supply requirement of portable electronic devicesPeople in switching power supply technical fields are edge developing related power electronics device, the side of frequency conversion technology, development of switch between mutual promotion push switch power supply with more than two year growth toward light, digital small, thin, low noise and high reliability, anti-interference direction. Switching power supply can be divided into the AC/DC and DC/DC two kinds big, also have AC/AC DC/AC as inverter DC/DC converter is now realize modular, and design technology and production process at home and abroad, are mature and standardization, and has approved by users, but the AC/DC modular, because of its own characteristics in the process of making modular, meet more complex technology and craft manufacture problems. Thefollowing two types of switch power supply respectively on the structure and properties of this.Switching power supply is the development direction of high frequency, high reliability, low consumption, low noise,anti-jamming and modular. Because light switch power, small, thin key techniques are changed, so high overseas each big switch power supply manufacturer are devoted to the development of new high intelligent synchronous rectifier, especially the improvement of secondary devices of the device, and power loss of Zn ferrite (Mn) material? By increasing scientific and technological innovation, to enhance in high frequency and larger magnetic flux density (Bs) can get high magnetic under the miniaturization of, and capacitor is a key technology. SMT technology application makes switching power supply has made considerable progress, both sides in the circuit board to ensure that decorate components of switch power supply light, small, thin. The high frequency switching power supply of the traditional PWM must innovate switch technology, to realize the ZCS ZVS, soft switch technology has become the mainstream of switch power supply technical, and greatly improve the efficiency of switch power. For high reliability index, America's switch power producers, reduce by lowering operatingcurrent measures such as junction temperature of the device, in order to reduce stress the reliability of products made greatly increased.Modularity is of the general development of switch power supply trend can be modular power component distributed power system, can be designed to N + 1 redundant system, and realize the capacity expansion parallel. According to switch power running large noise this one defect, if separate the pursuit of high frequency noise will increase its with the partial resonance, and transform circuit technology, high frequency can be realized in theory and can reduce the noise, but part of the practical application of resonant conversion technology still have a technical problem, so in this area still need to carry out a lot of work, in order to make the technology to practional utilization.Power electronic technology unceasing innovation, switch power supply industry has broad prospects for development. To speed up the development of switch power industry in China, we must walk speed of technological innovation road, combination with Chinese characteristics in the joint development path, for I the high-speed development of national economy to make the contribution.。
