1、附录 3:外文翻译资料 Development of Sensor New Technology Sensor is one kind component which can tansform the physical quantity, chemistry quantity and the biomass into electrical signal. The output signal has the different forms like the voltage, the electric current, the frequency, the pulse and so on, whi
2、ch can satisfy the signal transmission, processing, recording, demonstration and control demands. So it is the automatic detection system and in the automatic control industry. If automatic Technology is used wider, then sensor is more important. In information age, the information industry includs
3、information gathering, transmission, process three parts, namely sensor technology, communication, computer technology. Because of ultra large scale integrated circuits rapid development after having been developed ,Modern computer technology and communication, not only requests sensor precision, re
4、liability, speed of response and gain information content request more and more high, but also requests its cost to be inexpensive. The obvious traditional sensor is eliminated gradually because of the function, the characteristic, the volume, the cost and so on. As world develop many countries are
5、speeding up to the sensor new technologys research and the development, and all has obtained the enormous breakthrough. Now the sensor new technology development, mainly has following several aspects: Firstly, discovering and using. Using the physical phenomenon, the chemical reaction, the biologica
6、l effect as the sensor principle therefore the researches which discovered the new phenomenon and the new effect are the sensor technological improving ways .it is importantstudies to develope new sensors the foundation. Japanese Sharp Corporation uses the superconductivity technology to develop suc
7、cessfully the high temperature superconductivity magnetic sensor and get the sensor technology significant breakthrough. Its sensitivity is so high and only inferior in the superconductivity quantum interference component. Its manufacture craft is far simpler than the superconductivity quantum inter
8、ference component. May use in magnetism image formation technology.So it has the widespread promoted v alue. Using the immune body and the antigen meets one another compound when the electrode surface.It can cause the electrode potential change and use this phenomenon to be possible to generate the
9、immunity sensor. The immunity sensor makes with this kind of immune body may to some organism in whether has this kind of anti- original work inspection. Like may inspect somebody with the hepatitis virus immune body whether contracts the hepatitis, plays to is fast, the accurate role. The US UC six
10、th branch has developped this kind of sensor. Secondly, using the new material. The sensor material is the important foundation for sensor technology, because the materials science is progressive and the people may make each kind of new sensor. For example making the temperature sensor with the high
11、 polymer thin film; The optical fiber can make the pressure, the current capacity, the temperature, the displacement and so on the many kinds of sensors; Making the pressure transmitter with the ceramics. The high polymer can become the proportion adsorption and the release hydrone along with the en
12、vironment relative humidity size. The high polymer electricity lies between the constant to be small, the hydrone can enhance the polymer the coefficient of dielectrical loss. Making the capacitor the high polymer dielectric medium, determines the electric capacity capacity the change, then obtains
13、the relative humidity. Making the plasma using this principle to gather the legitimate polystyrene film temperature sensor below, it has the characteristic: Measured the wet scope is wide; The temperature range is wide, may reach -400 +1,500 ; The speed of response is quick, is smaller than 1S; The
14、size is small, may use in the small space measuring wet; The temperature coefficient is small. The ceramic electric capacity type pressure transmitter is one kind does not have the intermediary fluid the dry type pressure transmitter. Uses the advanced ceramic technology, the heavy film electronic t
15、echnology, its technical performance is stable, the year drifting quantity is smaller than 0.1%F.S, warm floats is smaller than 0.15%/10K, anti- overloads strongly, may reach the measuring range several hundred times. The survey scope may from 0 to 60mpa. German E+H Corporation and the American Kavl
16、io Corporation product is at the leading position. The optical fiber application is send the material significant breakthrough, its uses in most early the optical communication techniques. In the optical communication use discovered works as environmental condition change and so on the temperature,
17、pressure, electric field, magnetic field, causes the fiber optic transmission light wave intensity, the phase, the frequency, change and so on the polarization condition, the survey light wave quantity change, may know causes these light wave physical quantity the and so on quantitative change tempe
18、rature, pressure, electric field, magnetic field size, uses these principles to be possible to develop the optical fiber sensor. The optical fiber sensor and the traditional sensor compare has many characteristics: Sensitivity high, the structure simple, the volume small, anti-corrosive, the electri
19、c insulation good, the path of rays may be curving, be advantageous for the realization telemetering and so on. Optical fiber sensor Japan is in the advanced level. Like Idec Izumi Corporation and Sunx Corporation. The optical fiber send receiver and the integrated path of rays technology unify, acc
20、elerates the optical fiber sensor technology development. Will integrate the path of rays component to replace the original optics part and the passive light component, enable the optical fiber sensor to have the high band width, the low signal processing voltage, the reliability high, the cost will be low. Third, micro machine-finishing technology In semiconductor technology processing method oxygenation, the photoetching, the proliferation, the deposition, the plane electron craft, various guides co
