The test results obtained by National Defense Underwater Acoustic Metrology center show that, the FOH presented in this dissertation has extremely low acceleration sensitivity and excellent performance, which can completely satisfy the towed linear array application.The main results and the creative points of the present dissertation are as follows:1. A novel FOH structure is presented.

在国防水声一级计量站对(来源：ABe5f5e5C论文网www.abclunwen.com)所研制的拖曳线列阵光纤水听器的综合性能指标进行了全面测试，测试结果表明本论文研制的拖曳线列阵用光纤水听器具有很低的加速度灵敏度和很好的综合性能，已能满足光纤水听器拖曳线列阵的应用要求，这为光纤水听器拖曳线列阵的发展奠定了基础。

With coupler embedded and acceleration sensitivity compensation design, the structure symmetry is insured, which can induce the acceleration sensitivity effectively. The acceleration sensitivity compensation design also improves the production efficiency of FOH for towed linear array application.2. A good theoretical simulation platform, utilizing the method of elastic mechanics and the finite element method, is established, which can provide an effect predictive design for FOH. The experimental results are in good agreement with the theoretical analysises.3. Some key technology problems in the making of FOH for towed linear array application are conquered. The new developed FOH, with an acoustic sensitivity of -143.0dB, has acceleration sensitivity less than -30dB, which exceeded to results from other international reports.

本论文的主要成果和创新在于：1、提出了耦合器内嵌、带加速度灵敏度微调补偿的低加速度灵敏度光纤水听器结构，最大程度保证了工艺结构的对称性，实现了对工艺误差的有效补偿，提高了低加速度灵敏度光纤水听器研制的成品率。2、采用弹性力学和有限元方法建立了拖曳线列阵光纤水听器理论设计平台，实验与理论分析结果相一致，这为优化光纤水听器的结构设计提供了有效的技术手段。3、解决了拖曳线列阵用光纤水听器制造的关键技术问题，研制出声压灵敏度为-143.0dB，加速度灵敏度低于-30dB的拖曳线列阵用光纤水听器，其加速度灵敏度优于国际上已报导的结果，并在国防水声一级计量站对其进行了性能指标测试(来源：A14BC论文网www.abclunwen.com)。

Experiment data of HCB desorption were simulated better by fast2slow two stage first2order kinetics model and dynamic parameters of HCB desorption were also calculated. Frap and Fslow , the fractions of contaminant present in the rapidly and slowly desorbing sediment compartment , were respectively 3716 % and 6214 %; krap and kslow , the rate constants of rapid and slow desorption , were 01066 9h - 1 and 01000 5h - 1 , respectively.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
