In addition this technology is implemented in this experiment . when liquid - core optical fiber is combined with raman spectrum , the optical intensity of raman spectrum can be enhanced with the increasing length of liquid - core optical fiber 实验结果表明，在液芯光纤内产生喇曼效应是随着泵浦激光束与喇曼介质作用体积增加，从而使被激发的喇曼光在光纤的传播中不断被累积而得以增强。
Different liquid systems can be used in different wavebands . so the choice of liquid core is greatly abroad . in recently , there are many researches reported , but these researches mostly focus on its optic spectrum and easy application 近年来，液芯光纤的研究也有不少报道，但这些研究大多停留在对其光谱特性以及一些简单的应用研究，其应用层次比较低，应用面比较窄，并没有得到广泛的推广。
In the thesis , the research of lcof is put forward , and the lcof is used to inspect the state of the composite materials . in this paper , the lcof is developed by self . the mainly researches of the lcof are following ( 1 ) experiment on capability of bear the weight of the lcof , and compared with usually optic fiber 本文对自研制的液芯光纤进行了性能实验和初步的应用研究，主要研究内容有： ( 1 )液芯光纤承载性能的实验研究：通过与普通光纤承载性能的对比，结果表明本文研制的液芯光纤和普通光纤一样具有良好的承载传感性能。
As is shown in this paper , when the length of liquid - core optical fiber full of liquid of carbon disulfide disulphide is four meters , the maximum raman spectrum can be received , compared it with optical spectrum measured by absorption cell , it is enhanced by more than one hundred times 采用此联用技术，当液芯光纤芯内样品为二硫化碳( cs _ 2 ) ，液芯光纤的长度为4米时获得的喇曼光谱强度最大。此时的喇曼光谱强度比吸收池方法获得的喇曼光谱强度提高两个数量级以上。
In this paper , the technology of making liquid - core optical fiber is introduced . the fundamental principle and measuring methods of raman spectrum of liquid - core optical fiber are discussed . the possibility of combining raman spectrum with liquid - core optical fiber is analyzed as well 本文介绍了液芯光纤封头技术与液芯光纤的制作方法，论述了液芯光纤喇曼光谱的测试原理及测试方法，分析了把液芯光纤的低损耗、高增益、良好稳定性等优点用于光谱技术的可行性，并在实验上验证了这种光纤喇曼联用技术具有可行性。
