3.关于科学的英语小作文{60词}
Science is both a body of knowledge and a process. In school, science may sometimes seem like a collection of isolated and static facts listed in a textbook, but that's only a small part of the story. Just as importantly, science is also a process of discovery that allows us to link isolated facts into coherent and comprehensive understandings of the natural world.
Science is exciting. Science is a way of discovering what's in the universe and how those things work today, how they worked in the past, and how they are likely to work in the future. Scientists are motivated by the thrill of seeing or figuring out something that no one has before.

As we all know that the popularizing rate of the scientific knowledge for Americas isn't high,so is the chinese.In fact,the popularizing rate of a country is very important for it is related with the development and progress of the country.
Duo to China once was a feudal state owning more than two thousand years' history,some superstition still exists in many people's mind.In order to raise the popularizing rate of scientific knowledge,we should follow the prescribed order.
Firstly,we can open up some courses about the scientific knowledge in the kingdergatens,primary schools and middle school.Besides,some scientific knowledge can be introduced to the young through the form of cartoons to raise their interests.
Secondly,some activities with award about the scientific knowledge can be held in cities and countryside to raise the scientific knowledge of the middle and old aged people.
Therefore,let's try our best to learn more about the scientific knowledge to make a difference both for ourselves and our motherland.
希望能帮上你！！

7.2分钟英语演讲短文（关于科学一类）
你好~这是完整的有点长~~你看这随便摘录下就行了~祝你好运~O（∩_∩）OThe control of Electronic Communication With computer technology, communications technology, the rapid development of integrated circuit technology to all-digital fieldbus-represented on-site control instruments, equipment, a large number of applications, the traditional site of the control technology and control equipment at the scene has changed dramatically. The site was cumbersome to connect a single simple field bus network in place of the system design flexibility, easy maintenance, quality of the signal transmission is also greatly enhanced, in order to control the on-site industrial users tremendous advantages. After a long period of development, has become Hart, Lonworks, Profibus, Bitbus and a variety of on-site, such as CAN bus protocol. With the rapid development of electronic technology in the car and on the wider use of electronic vehicle becoming more, especially micro-controller into the car in the field of control, to the development of the automobile has brought epoch-making changes in the car driving force, Stability operations, safety, fuel economy, environmental friendliness have been increased dramatically. The application of a large number of electronic devices, wiring body is bound to lead to the more complicated the longer run to reduce the reliability, fault repairs difficult. In particular the electronic control unit of the large scale introduction, in order to raise the utilization rate of the signal, a large number of requests for information in various electronic units shared, integrated vehicle control system in a large number of control signals need to exchange real-time, Cambodia has been far from the traditional line This can not meet the demand. In response to these problems, the choice of network technology in computer network technology from the scene and control technology on the basis of the development of the automobile environment applies to all kinds of car networking technology. And other on-site control, the car temperature range (-45-100 ℃)， electromagnetic interference and other electronic noise-keung, environment, network reliability in the operation of the car is especially important that this not only reflected in the structure of the network itself The fault-tolerance and anti-interference ability, but also in the signal encoding and transmission methods. Automotive LAN, without exception, have adopted a serial synchronous transmission, data and the PWM signal the use of NRZ encoding, bit rate is usually higher than that of NRZ encoded using 100kbps, which is lower than 100kbps encoding using PWM. Many well-known international car company in the early 80's on the active network dedicated to automotive technology research and application. To date, a variety of network standards such as SAE's J1850, Germany's public ABUS, the Bosch CAN, the American Business Machines AutoCAN, ISO's VAN, such as Mazda's PALMNET. In accordance with China's automotive electronics technology development planning, into the 21st century car electronics up to the level of 90 foreign countries, will also be a large number of intelligent electronic control unit was introduced. To shorten the car with foreign skills, improve their own competitiveness, relying on technology alone is not conducive to long-term growth, digestion, absorption, research and development of its own network of automotive applications is imperative 又找了篇关于彩虹的A scientific explanation of rainbowThe rainbow's appearance is caused by dispersion of sunlight as it goes through raindrops. The light is first refracted as it enters the surface of the raindrop, reflected off the back of the drop, and again refracted as it leaves the drop. The overall effect is that the incoming light is reflected back over a wide range of angles, with the most intense light at an angle of 40°–42°. The angle is independent of the size of the drop, but does depend on its refractive index. Seawater has a higher refractive index than rain water, so the radius of a 'rain'bow in sea spray is smaller than a true rainbow. This is visible to the naked eye by a misalignment of these bows.[2]The amount by which light is refracted depends upon its wavelength, and hence its colour. Blue light (shorter wavelength) is refracted at a greater angle than red light, but because the area of the back of the droplet has a focal point inside the droplet, the spectrum crosses itself, and therefore the red light appears higher in the sky, and forms the outer colour of the rainbow. Contrary to popular belief, the light at the back of the raindrop does not undergo total 。
