Aiming at the diversification of function system and homing modes in the development of submarine-launched torpedo, this paper analyses the advantages in operational application of wake homing torpedo based on its mechanism, such as stronger counter-countermeasure, higher speed, and higher target acquisition probability for selected target. It also analyses the limitations in tactics, such as limited attacking speed and the types of attackable targets, greater loss in torpedo range, difficult combination with wire-guidance, and inaccurate attack on moving targets.

针对国内外潜射鱼雷在功能体制和制导方式等技术环节多元化发展的局面，基于尾流自导鱼雷制导原理，分析了尾流自导鱼雷在作战使用上的技术优势：抗干扰能力强，适宜高速制，可选择攻击目标和捕获概率高；以及其战术局限性：可攻目标的类型及速度受限，鱼雷航程损失大，与线导结合困难，对机动目标攻击效果较差。

On the base of Pearson correlation coefficient indicate that the connection between IBI and CQHEI is higher than IBI and ISC of Juoshuei river basin. To the section of the upper and middle reaches, we suggest choosing simple and convenient SIAM to be the standard for environment in the future. But due to the type of ecosystem has a tendency to estuary ecosystem at the lower reach of Juoshuei river basin, SIAM is more unsuitable for evaluating at the reach. The correlation between each index is not notable, so we suggest seeking other assessment method as comparative environmental standards.

由指标相关性讨论可知栖地品质与生物完整性相关性较高(r=0.649)，水质状态与生物完整性相关性则较低(r=0.267)，对於中上游河段部分，建议日后进行河川生态环境调查时可选择简便易用的SIAM模式做为标准；下游近海河段则因河川型态渐转变为河口生态系的型态，故适用於溪流生态系的SIAM在适用性上较差，各指标间相关性并不显著，建议可寻求其他评估模式做为环境品质的判断标准。
