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.)

NTKL法可以同时检测光谱异常点、参考数据异常点及其他们共同的异常点，该方法的基本思路是基于蒙特卡洛采样，随机将样本集划分为校正集与预测集，用校正集建模，并对没参与建模的样本进行预测误差计算，进行几千次这样随机采样，每个样本点都可得到其预测误差分布。如果奇异样本在校正集中，整个模型的质量将受到影响；相反，如果奇异样本在预测集中，仅此样本的预测结果受到影响。(NTKL method can simultaneously detect abnormal spectrum and abnormal reference data points and their common abnormal point, the basic idea of this method is based on the monte carlo sampling, sample set random be divided into calibration set and prediction set, using correction modeling, modeling and participated in the samples of the prediction error calculation, a thousands of times that of random sampling, each sample point can be obtained the prediction error distribution.If singular samples in correction, the model of quality will be affected.Singular samples in predicting concentration, on the contrary, if only for the sample prediction results are affected.)
