- So how to defend the surface ship against the torpedo has been the key point in antisubmarine warfare. 摘要如何对来袭鱼雷进行防御成为水面舰艇对潜防御作战的重中之重。
- Tow ship noise is a nonstationary process with several characteristic properties, such as multi-path and angle dispersion, which greatly add the difficulty to cancel or suppress the noise. 拖曳式线列阵声纳的拖船噪声具有多途角扩展等特点，并且是一个非平稳过程，使得对该噪声的消除或抑制是一大难点。
- The most dangerous threat for surface ship formation is from the air in the future. 未来海战中,水面舰艇编队所面临的最大威胁主要来自空中。
- The flow chart of surface ship counterattacking submarine of surface ship based on torpedo trajectory was described. 描述了水面舰艇基于潜射鱼雷弹道特征的防潜反击体系流程。
- The evolution process of the surface ship s antisubmarine system and the problems existed are analyzed. 作战舰艇生命力是衡量舰艇作战能力的重要因素,其评估是对复杂系统的研究过程。
- Shemsen did not add that one surface ship and all the sahuagin-crewed fliers in the sea would not be enough against the might of Waterdeep. 而一艘水面舰船和海里所有沙华鱼人的快艇也无法反抗深水城的力量，舍姆森隐瞒了这点。
- A New Method for Feature Extraction in Ship Noise 基于多重分形的舰船噪声特征提取
- This article qualitative introduced the use tree planting method, during beautified environment, reduces the ships noise to the environment pollution, expanded the tree planting potency. 摘要针对船舶噪音与居住环境的矛盾逐渐突出，提出了利用绿化手段，降低船舶噪音对环境的污染，扩展了绿化的效能。
