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。

Being short of regulation and relative theory, it is difficult to calculate the compensation of attainable interest.

在审判实践中，由于缺乏法律条文和理论上的支持，可得利益赔偿的计算困难重重。

The channel type is so multiplicity that transpot water attemper is very difficult.

Compared to wet season, arsenic is difficult to mobile in dry season. Attenuation constant in dry season is 0.3082(1/km), but it is 0.0569(1/km)in wet season. If initial concentration of As was 500μg/L without other contamination source in down stream, arsenic would deceased to 50μg/L in down stream 7.5km in dry season but 40km in down stream 40km. As is dominate species in river running throμgh mining area.

砷在枯水期较丰水期难以迁移，通过计算得到，在枯水期砷的衰减系数K值为0.3082(1/km)，而在丰水期为0.0569(1/km)；在污染口浓度达到500μg/L时，下游没有其它的砷的污染源(或会影响砷衰减的其它污染源)时，枯水期砷会在下游7.5km之后浓度降到50μg/L，而丰水期则要在下游40km之后才能降到同样的值，所以在丰水期砷污染的影响的流域更广。

To find out the modifier in the attributive clause is always a difficult problem in its translation.

定语从句的修饰对象1直是翻译中经常遇到而难以把握的问题。
