Market demand survey meter analysis is very important, sweat hair products to market, sell and profit. Foreign manufacturers attach great importance to the analysis of market research, before settling in a new product development, light of investigation report a heap of tens of centimeters. One of the main application, technology, advanced technology, feasibility, industry and national preferential policies, investment analysis, prehensive benefits, market demand, and many other aspects of a prehensive feasibility discussion. The sensor technology development generally experienced the following four stages: (1) structure type sensor such as a strain type displacement meter (2) physical sensors such as solidstate piezoresistive pressure sensor (3) intelligent sensor such as the United States of America Hone Will pany ST3000 smart pressure sensor, it with a microprocessor, with detection and information processing function. Since the diagnosis, adaptive function. (4) molecular sensor, it is the use of bamboo for the configuration and conformation and exhibit electromagic phenomena as the theory base and production. Notable features: small size to the bamboo, and is posed of a large molecule or molecular devices. The human body is all kinds of sensor gathering place, and most anisms are molecular sensors sensors. So far, the real sensor, only to find, this suggests that in vivo, can make use of gene engineering, biosynthesis and molecular sensor system. Some people are expected in the future of the century the ing of the era of molecular sensor. On the development of sensor technology issues in twentyfirst Century, to the point of personal views: sensor support technology is the micro machining technology, including microelectronics and micromachining technology, sensor technology, petition will be the manufacturing process from the chip into packaging technology petition. New packaging technique such as anodic bonding, flip chip bonding, flip chip technology will have greater development of new. Should rise to the rapid development of information industry and environmental protection industry in twentyfirst Century, the sensor market will have greater development, seize the opportunities for development of sensor, seize the 畢業(yè)設(shè)計(論文) —— 外文文獻原稿和譯文 5 opportune moment to develop new products, and gradually formed the industry, will form a new growth point of national economy. Multisensor information fusion technology. The United States Air Force Technical College using the information fusion method for the determination of moving target research work was selected in forwardlooking infrared sensor and a distance sensor, infrared image and visual image of dozens of pieces of distance nearly 100 information fusion based on the parative analysis, the analysis method and the Bias minimum error classification criteria of feature level fusion, the moving target detection accuracy is greatly increased. The world of micro electronic mechanical sy
