Second , although substantially improved in these areas , it still needs more and better antisubmarine and antiaircraft capabilities to protect a carrier and its supporting vessels 其次,虽然大大改善这些地区还需要更多更好的反潜和防空能力,保护承运人及其辅助船
To develop the equipment and the theory of antisubmarine warfare ( asw ) and submarine operation , the characteristic and insufficiency of the platform centric antisubmarine warfare are researched 摘要为发展反潜作战、潜艇作战装备及理论，对平台中心反潜战中的特点和问题进行了研究。
The concept of a specialized surface ships was developed by soviet designers . two different types of warships were laid down which were project 956 destroyer and project 1155 large antisubmarine ship 前苏联的舰船设计者们采取了一条非同一般的水面战舰发展思路，同时发展了两型不同的战舰，即956计划驱逐舰和1155计划大型反潜舰。
In this paper , a space model of antisubmarine homing torpedo ' s trajectory has been established based on the surface warship attacking underwater target , a formula which can be used to calculate the trajectory length of antisubmarine horning torpedo is also given 在建立了水面舰艇发射反潜自导鱼雷攻击水下目标的空间弹道模型的基础上，提出了反潜自导鱼雷全弹道长度的一种计算公式。
They have also been exported to iran , china , india , poland , romania and algeria . china has two type 636 submarine which are designed for antisubmarine and anti - surface ship asuw warfare as well as for general reconnaissance and patrol missions 636型潜艇是在877型的基础上又进行了改进提高，其降低动力装置的转速，采用了七叶大侧斜螺旋桨，增大充电功率提高了充电能力，改进降噪措施，进一步降低了噪声。
And the composing of the network of asw in the network centric antisubmarine warfare is introduced , the basic function of the network of asw and the relationship of the sub - net is discussed especially , and then the threaten to the submarine operation from the network centric antisubmarine warfare is presented 介绍了美军网络中心反潜战中的反潜战网络组成，探讨了反潜战网络的基本功能、各子网络的关联和网络中心反潜战对潜艇作战的威胁。
In my paper i will analysis the characters of dis , design principle of dis system and the key techniques of dis such as computer network technology etc . based on the analysis and research of the techniques above , i will discuss the application in the army - field ; finally , i will introduce the comprehension and experience in developing the dis system of naval certain surface vessel formation antisubmarine training simulator which author has taken part in 本文将分析分布交互仿真系统的基本特点、设计原则和主要的关键技术。重点分析、研究计算机网络技术和计算机实时仿真技术等在分布式作战训练仿真系统中的具体应用，最后结合作者参与的《某指控中心作战训练仿真系统》研究的实践谈一些体会，并对其进行必要的展望。
Based on the real situation of submarine and antisubmarine warfare ( asw ) , according to the classical design theory of transducer or transducer array , a sonar will be researched and made , which has the feature of more wider bandwidth , more lower operating frequency , more lager radiation acoustic power , more farther operating distance , more higher researching efficiency and more higher directive accuracy 本文根据现代潜战和反潜战( asw )的实际情况，按照经典的换能器和基阵的设计理论，研制声呐，旨在扩展其频带宽度、降低其工作频率、增大其发射功率、扩大其作用距离以及提高其搜索效率和定向准确度。
Another based mathematics model about the anchor cable is used for ship - anchor system . the numerical calculation have been worked by programmed in the matlab language . at the same time the influence that the dragging speed of antisubmarine helicopter and the height over the surface of ocean acts on the shape and the tension of underwater cable , and that the current velocity and the diameter of anchor cable acts on the shape and the tension of anchor cable , has been calculated 把建立的水下拖索数学模型和锚索数学模型分别应用于航空吊放声纳探头?缆绳动力学系统和船?锚系统，采用matlab语言编程进行了数值计算，同时分别计算和分析了反潜直升机拖速、距海面高度对拖索形状和张力的影响以及海流速度、锚索直径对锚索形状和张力的影响。
