In order to improve the tactical efficiency of the wire-guided torpedo with multispeed, the torpedo launch platform should offer some different guidance methods, so that the torpedo may take shorter time to approach the target with high speed, and keep lower radiation noise to make better use of the sonar detection with low speed.

据此提出为了真正发挥多速制线导鱼雷的战术效能，发射平台应提供交替使用鱼雷不同速制的导引方法，以便既能够发挥鱼雷高速制速度快、接近目标时间短的优势，又能发挥鱼雷低速时辐射噪声小、利于平台声纳探测的特长。

The general design concept in France is discussed in this paper, which integrates ship platform, combat system, torpedo threat, countermeasure design and outside sea trials. To obtain a countermeasure system with low cost and high performance, the design concept of the Scorpene submarine includes the following three sides:(1) optimizing torpedo countermeasures based on torpedo threat characteristics and subsequent operational reactions;(2) integrating combat system and platform;(3) simulating operational reaction efficiency based on actual operational schemes.

本文介绍了法国海军潜艇设计机构长期研制反鱼雷对抗系统所积累的经验，该机构以&天蝎星&潜艇设计为例提出了一种基于将舰艇平台、作战系统、鱼雷威胁、对抗系统设计以及外场海上试验结合在一起综合考虑的整体设计理念，即根据鱼雷的威胁特性和后续的作战响应优化鱼雷对抗系统、集成作战系统与平台，以及基于实战方案进行舰艇反应效率仿真，以此获得低成本高性能的对抗系统。

Though we have make much progress on it, there remains many problems to study deeply, of which its supporting software system developing is an important and elementary subject of torpedo trajectory research.In this article, we bring forward the double-color method for stereodisplay of the torpedos trajectory.

在鱼雷弹道研究方面已经取得了可喜的成果，但仍不能满足鱼雷事业新发展的要求，需要深入研究的问题还很多，其中鱼雷弹道软件系统的开发仍是鱼雷弹道研究中的一项重要而又基础性的课题。

The double-color method and theory for stereodisplay of the torpedos trajectory are presented in this article. Program which is using the programming language of Visual C++6.0+MFC+OpenGL has been compiled. In this program, torpedo can be displayed in stereodisplay mode, which can be controlled adapting to the changing of time and space. The final data can easy be simulated and calculated. This method is meaningful to torpedo trajectory design and research.

本文提出了鱼雷弹道双色立体显示技术，系统的介绍了鱼雷弹道立体显示的原理和方法，并采用Visual C++6.0+MFC+OpenGL软件结构编制了相应的程序，使鱼雷最终能够直观的，以图象信息表示出其随时间和空间变化过程，即以立体图象呈现在研究者面前，从而能够更为方便地模拟和计算，对鱼雷弹道的研究和设计具有十分重要的意义。

Sting Ray represents the first generation of programmable torpedoes and attention has been turned to the problems of how to harness the vast computer powers now available with their associated software programs, how to package the maximum computer power in the smallest possible space, and how to improve still further the processing and filtering techniques so vital to exclude extraneous noise and vibration.

分析：并列分句attention has been turned to the problems…里的the problems后的介词of 接有三个由疑问词how +动词不定式短语构成的并列成分。filtering techniques：滤波技术，鱼雷利用该技术可以滤掉海洋里产生的干扰声源和鱼雷在水里运动时产生的振动和噪声，所有这些干扰都会对装在鱼雷上的声纳产生干扰，从而影响其探测功能。译文：&鳐鱼&代表着第一代程序控制鱼雷。人们已经将注意力转到如何利用现有的巨大计算机能力及其相关软件程序，如何在尽可能小的空间内容纳最大的计算机能力，以及如何更进一步改进对于排除外来噪声和震动来说至关重要的处理与滤波技术等问题上。
