科技散文翻译练习
科技散文翻译练习Please translate the following scientific prose into Chinese.If we look at the sky on a perfectly fine summer’ sday we shall find that the bluecolor is the most pure and intense overhead, and when looking high up in a directionopposite to the sun. Near the horizon it is always less bright, while in the regionimmediately around the sun it is more or less yellow. The reason of this is that nearthe horizon we look through a very great thickness of the lower atmosphere, whichis full of the larger dust particles reflecting white light, and this dilutes the pure blueof the higher atmosphere seen beyond. And in the vicinity of the sun a good deal ofthe blue light is reflected back into space by the finer dust, thus giving a yellowishtinge to that which reaches us reflected chiefly from the coarse dust of the loweratmosphere.At sunset, however, this last effect is greatly intensified, owing to the great thicknessof the strata of air through which the light reaches us. The enormous amount of thisdust is well shown by the fact that only can we look full at the sun, even when thewhole sky is free from clouds and there is no apparent mist. But the sun ’ s rays t reach us after having passed, first, through an enormous thickness of the higherstrata of the air, the minute dust of which reflects most of the blue rays away from us,leaving the complementary yellow light to pass on. Then, the somewhat coarser dustreflects the green rays, leaving a more orange-colored light to pass on; and finallysome of the yellow is reflected, leaving almost pure red. But owing to the constantpresence of air currents, arranging both the dust and vapor in strata of varying extentand density, and of high or low clouds which both absorb and reflect the light in varying degrees, we see produced all those wondrous combinations of tints and thosegorgeous ever-changing colors which are a constant source of admiration and delightto all who have the advantages of an uninterrupted view to the west and who areaccustomed to watch for those not infrequent exhibitions of nature ’ s kaleidoscopiccolor painting.With every change in the altitude of the sun the display changes its character, andmost of all when it has sunk below the horizon, and owing to the more favorableangles a larger quantity of the colored light is reflected toward us. Especially whenthere is a certain amount of cloud is this the case. These, so long as the sun wasabove the horizon, intercepted much of the light and color; but when the greatluminary has passed away from our direct vision, his light shines more directly onthe under sides of all the clouds and air strata of different densities; a new and morebrilliant light flushes the western sky, and a display of gorgeous ever-changing tintsoccurs which are at once the delight of the beholder and the despair of the artist.And all this unsurpassable glory we owe to—dust!晴空万里的夏季，假如我们察看一下天空，背向太阳仰望，就会发现头顶上空的蓝色最纯净，最浓烈。

科技文体翻译练习1
科技文体翻译练习：The Biotech CenturyRing farewell to the century of physics．It’s time to ring in the century of biotechnology．The 20th century medicine did little to increase the natural life-span of healthy humans．The next medical revolution will change that, because genetic engineering has the potential to conquer cancer，grow new blood vessels in the heart，block the growth of blood vessels in tumors，create new organs from stem cells and perhaps even reset the primeval genetic coding that causes cells to age．Our children may be able(I hope，I fear)to choose their kids traits：to select their gender and eye color；perhaps to tinker with their IQs，personalities and athletic abilities．They could clone themselves，or one of their kids，or a celebrity they admire，or maybe even us after we’ve died．In the 5 million years since we hominids separated from apes，our DNA has evolved less than 2%．But in the next century we’ll be able to alter our DNA radically，encoding our visions and vanities while concocting new life-forms．When Dr．Frankenstein made his monster， he wrestled with the moral issue of whether he should allow it to reproduce：“Had I the right，for my own benefit，to inflict the curse upon everlasting generations ?”Will such questions require us to develop new moral philosophies?Probably not．Instead, we’ll reach again for a time-tested moral notion，one sometimes called the Golden Rule and which Kant，the millennium’s most meticulous moralist，guessed up into a categorical imperative：Do unto others as you would have them do unto you：treat each person as an individual rather than as a means to some end．Under this moral precept we should recoil at human cloning．Valuing them as copies of others we loved or as collections of body parts，not as individuals in their own right．We should use genetic engineering to cure diseases and disabilities (cystic fibrosis，muscular dystrophy) but not to change the personal attributes that make someone an individual (IQ，physical appearance，gender and sexuality)．The biotech age will also give us more reason to guard our personal privacy．Aldous Huxley，in Brave New World，got it wrong：rather than centralizing power in the hands of the state, DNA technology has empowered individuals and families．But the state will have an important role, making sure that no one，including insurance companies，can look at our genetic data without our permission or use it to discriminate against us．Then we can get ready for the breakthrough that could come at the end of the next century and is comparable to mapping our genes：mapping the 1O billion or more neurons of our brain．With that information we might someday be able to create artificial intelligences that think and experience consciousness in ways that are indistinguishable from a human brain．Eventually we might be able to replicate our own minds in a machine, so that we could live on without the biological brain and body．The 20th century’s revolution in info-technology will merge with the 21st century’s revolution in biotechnology．生物技术世纪现在是告别物理学世纪、迎接生物技术世纪的时候了。

Rise of 'cyberathletes' could changesport as we know it“电子运动员”的兴起将会改变我们熟知的运动Now 31, Lewis is fresh from winning a gold medal at the Madrid World Paratriathlon in September. The achievement owes much to his determination to succeed, but technology has also finally caught up with his ambition.现今31岁的路易斯于九月刚刚荣获了在马德里举行的残奥会。
此番成就很大程度上要归功于他求胜的决心，但是科技的功劳还是远远超过了他的雄心。
Lewis won the race using an Ottobock S380, the first above-the-knee prosthetic leg specially made for athletes. A lightweight, shock-absorbing frame allows for greater speed and comfort, and a flexible knee joint provides range of movement and versatility that enables Lewis to make rapid transitions from the pool to bike to track -- which shaved critical seconds off his winning time.路易斯在此次比赛中使用了“奥托博克s380”假肢，这是第一款专门为运动员设计的膝上假肢。
一个重量偏轻、减震框架更具吸引力的假肢为运动员提高速度与舒适度提供了可能，膝盖上灵活的接缝也为移动和与比赛的“多变性”提供了方便，这使得路易斯能在池塘、自行车、与跑到间迅速的转换—而且还是遥遥领先于亚军。

What Is a SketchThe mechanic must not only know how to read the language of the industrial world but must also know how to write it. He must be able to give his own ideas and describe an object to someone else. It is often necessary to make just a part for a machine. However, there is no time to make a drawing of it with instruments, no time either for a draughtsman to make a drawing. Sometimes only one piece of a machine part is to be made and, therefore, it would be inconvenient to have the draughtsman make a mechanical drawing.Sketches are important because they show ideas and dimensions of a machine part. The cleverest idea, however, may result in a great mistake if the sketch is poorly done. We must learn to make clean sketches to be easily read by others as well as by ourselves.Machine ElementsA machine consists of a number of machine elements. The most useful machine element in power transmission is the gear. The gear is virtually a wheel with a number of teeth. Gears must work in pairs. A pair of gears with different number of teeth will increase or decrease the speed of rotationPulleys and belts are very common in power transmission. They can also change speeds on machine tools. Gears or pulleys rotate on shafts. Theshaft must rest in bearings. Sometimes there may be couplings between shafts. We may use clutches to start or stop shaft motion.Some machine elements may be very large. Others may be very small. However, each of them plays a part in the construction of a machine.Cutting ToolsThe metal cutting tool separates chips from the workpiece in order to cut the part to the desired shape and size. There is a great variety of metal cutting tools. Each of them is designed to perform a particular job or a group of metal cutting operations in an efficient manner. For example, a twist drill is designed to drill a hole which has a particular size, while a turning tool may be used to turn a variety of cylindrical shapes.There are three basic types of metal cutting tools: single-point tools, multiple-point tools, and abrasives. A single-point metal cutting tool has a single cutting edge and is used for turning, boring, shaping, and planning. The most common machine tool that employs the single-point cutting tool is the engine lathe. Multiple-point tools have two or more cutting edges such as drills, reamers, and milling cutters. The cutting edge is that part of the tool where cutting is actually done. Grinding wheels are an example of abrasive cutting tools. Each grinding wheel hasa lot of abrasive grains which act as very small cutting tools.Limits and TolerancesMachine parts are manufactured so they areinterchangeable. In other words, each part of a machineor mechanism is made to a certain size and shape so itwill fit into any other machine or mechanism of the same type. To make the part interchangeable, each individual part must be made to a size that will fit the mating part inthe correct way. It is not only impossible, but alsoimpractical to make many parts to an exact size. This isbecause machines are not perfect, and the tools becomeworn. A slight variation from the exact size is alwaysallowed. The amount of this variation depends on the kindof part being manufactured. For example, a part might bemade 6 inches long with a variation allowed of 0.003( three thousandths ) inches above and below this size.Therefore the part could be 5.997 to 6.003 inches and stillbe the correct size. These are known as the limits. Thedifference between upper and lower limits is called the tolerance.When the tolerance is in both directions from the basic size, it is known as a bilateral tolerance ( plus and minus ). Sometimes the limit is allowed in only one direction. This is known as unilateral tolerance. For example, a hole may have to be 2 inches minus 0.000 inches, or plus 0.005 inches. This means that the hole must not be smaller than 2 inches, but can be as large as 2.005 inches.Surface FinishWithin recent years a great deal of attention has been given to the invesigation of the surface texture produced by various machining and finish operations, and, although we have not yet reached the stage when surface finish requirements can be specified and produced just as it is possible for a given dimension, information is being built up which may in the end bring this about.If a machine surface is reproduced to a large enough magnification it will be found to have a wevy profile, the character and shape of the waves varying for different machining methods. Equipment is now available which will produce an enlarged contour of a surface by traversing a needle-like probe over it, the instrument at the same time plotting on a chart a greatly magnified reproduction of the up-and-down movement of the probe with its longitudinal traverse.。
