科技知识英文短文什么是清洁能源 Clean Energy Clean energies are forms of energy which do not pollute the air, the ground, or the sea.Clean energies include:Solar powerSolar power describes a number of methods of harnessing energy from the light of the Sun. It has been present in many traditional building methods for centuries, but has become of increasing interest in developed countries as the environmental costs and limited supply of other power sources such as fossil fuels are realized. It is already in widespread use where other supplies of power are absent such as in remote locations and in space.As the Earth orbits the Sun, it receives approximately 1,400 W / m² of energy, as measured upon a surface kept normal (at a right angle) to the Sun (this number is referred to as the solar constant). Of the energy received, roughly 19% is absorbed by the atmosphere, while clouds on average reflect a further 35% of the total energy. The generally accepted standard is 1020 watts per square meter at sea level.After passing through the Earth's atmosphere, most of the sun's energy is in the form of visible and ultraviolet light. Plants use solar energy to create chemical energy through photosynthesis. We use this energy when we burn wood or fossil fuels or when we consume the plants as a source of food.Wind power Wind power is the kinetic energy of wind, or the extraction of this energy by wind turbines. This article deals mainly with the intricacies of large-scale deployment of wind turbines to generate electricity.Wave power Wave power refers to the capture of ocean surface wave energy to do useful work including electricity generation, desalination, and filling a reservoir with water. Wave power is a form of renewable energy. Though often co-mingled, wave power is physiologically distinct from the diurnal flux of tidal power and the steady gyre of ocean currents which are powered by the earth's rotation. Wave power generation is not a widely employed technology with only a few experimental sites in existence.Salinity gradient powerSalinity Gradient is a technology that takes advantage of the osmotic pressure differences between salt and fresh water.If we place a semipermeable membrane (like that in a reverse osmosis filter) between sealed bodies of salt water and fresh water, the fresh water will gradually travel through the filter by osmosis. By exploiting the pressure difference between these two bodies of water we can extract energy commensurate to the difference in pressure.Tidal power Tidal power is a means of electricity generation achieved by capturing the energy contained in moving water mass due to tides. Two types of tidal energy can be extracted: kinetic energy of currents due the tides and potential energy from the difference in height (or head) between high and low tides.Geothermal power Geothermal power is electricity generated by utilizing naturally occurring geological heat sources. It is a form of renewable energy.Some renewable energies are not clean energies - for example:Biofuels because they release NOX and particulates into the environment. Hydroelectric power because it destroys the river basin and has a negative effect on fish migration.。

第一篇Not long ago, many people believed that babies only wanted food and to be kept warm and dry. Some people thought babies were not able to learn things until they were five or six months old.Yet doctors in the United States say babies begin learning on their first day of life. The Eunice Kennedy Shriver National Institute of Child Health and Human Development is a federal government agency. Its goal is to identify which experiences can influence healthy development in human beings.Research scientists at the institute note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other human beings.第二篇Not long ago, many people believed that babies only wanted food and to be kept warm and dry.

The critical factors for real-time face detection are based on a framework of multiple classification functions: (1) a skin classification function is used as the preliminary stage in order to prune the search, localize the computation, and therefore improve performance time; (2) subsequently, three coarse-to-fine statistical model based classifiers are used to scan the windows and discard most non-face windows; and (3) finally, faces and non-faces are verified from images. The bagging ensemble algorithm (bootstrap aggregating) is also applied to improve the performance of detection rates. 第四篇Want a glance of the future of health care? Take a look at the way the various networks of people about patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient —no matter where he or she may be. Online doctors offering advice based on normal symptoms（症状） are the most obvious example. Increasingly, however, remote diagnosis（远程诊断） will be based on real physiological data（生理数据） from the actual patient. A group from the University of Kentucky has shown that by using personal data assistance plus a mobile phone, it is perfectly practical to send a patient's important signs over the telephone. With this kind of equipment, the cry asking whether there was a doctor in the house could well be a thing of the past. Other medical technology groups are working on applying telemedicine to rural(countryside) care. And at least one team wants to use telemedicine as a tool for disaster need—especially after earthquakes. On the whole, the trend is towards providing global access to medical data and experts' opinions. But there is one problem. Bandwidth（宽带） is the limiting factor for sending complex（复杂的） medical pictures around the world — CT photos being one of the biggest bandwidth users. Communication satellites may be able to deal with the short-term needs during disasters such as earthquakes or wars. But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of remote medical service. Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should start a new time when telemedicine and the sharing of medical information, experts' opinions and diagnosis are common.（这片有点长） 第五篇High-Tech Expo will be quietly into the footsteps of our campus, the annual "scientific and technological Month" activities started! We look forward to the most interesting is the High-Tech Expo will be it! Day after day 。

暗银河系的发现及其科学意义 In addition to conventional galaxies, the universe contains very dim galaxies that until recently went unnoticed by astronomers. Possibly as numerous as conventional galaxies, these galaxies have the same general shape and even the same approximate number of stars as a common type of conventional galaxy, the spiral, but tend to be much larger. Because these galaxies 'mass is spread out over larger areas, they have far fewer stars per unit volume than do conventional galaxies. Apparently these low-surface-brightness galaxies, as they are called, take much longer than conventional galaxies to condense their primordial gas and convert it to stars—that is, they evolve much more slowly. These galaxies may constitute an answer to the long-standing puzzle of the missingbaryonic mass in the universe. Baryons—subatomic particles亚原子粒子 that are generally protons or neutrons—are the source of stellar, and therefore galactic, luminosity, and so their numbers can be estimated based on how luminous galaxies are. However, the amount of helium in the universe, as measured by spectroscopy光谱学， suggests that there are far more baryons in the universe than estimates based on galactic luminosity indicate. Astronomers have long speculated that the missing baryonic mass might eventuallybe discovered in intergalactic space星系际的空间 or as some large population of galaxies that are difficult to detect. -------------------------------另类海豹哺乳方式与众不同 Until recently, zoologists believed that all species of phocids (true seals), a pinnipped family, use a different maternal strategy than do otariids (fur seals andsea lions), another pinniped family. Mother otariids use a foraging strategy. They acquire moderate energy stores in the form of blubber before arriving at breeding sites and then fast for 5 to 11 days after birth. Throughout the rest of the lactation (milk production) period, which lasts from 4 months to 3 years depending on the species, mother otariids alternately forage at sea, where they replenish their fat stores, and nurse their young at breeding sites. Zoologists had assumed that females of all phocids species, by contrast,use a fasting strategy in which mother phocids, having accumulated large energy stores before they arrive at breeding sites, fast throughout the entire lactation period, which lasts from 4 to 50 days depending on the species. However, recent studies onharbor seals, a phocids species, found that lactating females commenced foragingapproximately 6 days after giving birth and on average made 7 foraging trips during the remainder of their 24-day lactation period. The maternal strategy evolved by harbor seals may have to do with their small size and the large proportion of their fat stores depleted in lactation. Harbor seals are small compared with other phocids species such as grey seals, all of which are known to fast for the entire lactation period. Studies show that mother seals of these species use respectively 84 percent, 58 percent, and 33 percent of their fat stores during lactation. By comparison, harbor seals use 80 percent of their fat stores in just the first 19 days of lactation, even though they occasionally feed during this period. Since such a large proportion of their fat stores is exhausted despite feeding, mother harbor seals clearly cannot support all of lactation using only energy stored before giving birth. Though smallerthan many other phocids, harbor seals are similar in size to most otariids. In addition,there is already some evidence suggesting that the ringed seal, a phocids species thatis similar in size to the harbor seal, may also use a maternal foraging strategy.------------------------------pheromones是什么东东，是不是该划为odorantThere is no consensus among researchers regarding what qualifies a substance as a pheromone. While most agree on a basic definition of pheromones as chemicals released by one individual of a species which, when detected by another individual of the same species, elicit a specific behavioral or physiological response, some researchers also specify that the response to pheromones must be unconscious. In addition, the distinctionbetween pheromones and odorants—chemicals that are consciously detected as odors---can be blurry, and some researchers classify pheromones as atype of odorant. Evidence that pheromone responses may not involve conscious odor perception comes from the finding that in many species, pheromones are processed by the vomeronasal (or accessory olfactory) system, which uses a special structure in the nose, the vomeronasal organ (VNO),。
