综述了光纤光栅传感器近年来在工程结构健康监测、石油产业、电力行业、岩土工程、航空航天、采矿、爆破、交通及 医学等各个领域的应用情况。文章认为，限制光纤光栅传感器产业化和大规模应用的主要因素是缺乏统一的设计理论 和制作方法，这使得不同厂家生产的传感器规格存在差异。另外，由于复杂的生产技术和精细的生产过程使传感器生产 成本较高，而且能实际应用的光纤光栅传感器的解调产品并不多，且价格很高。根据上述分析，文中对该项技术未来的 发展方向提出了展望。(Overview of FBG sensors in recent years in various fields of engineering structural health monitoring, oil industry, power industry, geotechnical engineering, aerospace, mining, blasting, transportation and medical and other applications. Article that the main factor limiting FBG sensors and large-scale industrial applications is the lack of a unified design theory and production methods, which makes the sensors from different manufacturers specifications differ. In addition, due to the complexity of the production technology and sophisticated production process so that the sensor higher production costs, but also the practical application of fiber grating sensor product is not much, and the price is very high. Based on the above analysis, the article on the future direction of the technology raised the prospect.)

说明：  CA算法可以将数量型属性划分成若干个优化的区间，它综合了分层聚类于划分聚类的优点，对于给定的不同的初始类个数，CA算法能随着迭代过程的不断进展改变类的数目，一些竞争力差的类即类的基数小于给定阙值的类将在迭代过程中不断消失，最终得到能够有效体现数据实际分布情况的优化聚类个数。(CA algorithm for quantitative attributes can be divided into a number of the interval optimization, hierarchical clustering which combines the advantages of clustering in the division, for a given number of different types of initial, CA algorithm as the iterative process the continuous progress of change in the number of categories, some categories of poor competitiveness of the base type that is less than the value of a given category Que iterative process will continue to disappear and eventually be able to effectively reflect the actual distribution of data to optimize the number of clustering.)
