摘要：
提出一种海水密度的人工跃变技术，其核心思想是利用专门的材料和设备，通过特定机理在设定海域产生大量均匀分布的气泡，以形成足够规模的低密度海水区域，从而影响潜艇正常航行。通过验证性实验，分析不同大小及数密度的人工气泡制造海水跃变的实施效果和影响规律。实验结果表明：在静水中，气泡越小对潜艇航行掉深影响越大；在一定范围内，适当增加气泡的数密度能明显加大掉深深度。研究结论证明海水密度人工跃变思想的可行性与有效性，为潜艇军事打击手段的进一步完善以及装置的研制提供必要的基础和依据。

Abstract: An artificial pycnocline technology of seawater density is proposed in the paper and its core concept is to use special materials and equipment to generate a large number of evenly distributed bubbles in the special sea area via specific mechanism, so as to form a low-density sea water area in sufficient scale and affect the normal navigation of submarine. Through a specialized verification test, the effect and influence laws of seawater pycnocline caused by different artificial bubble radius and bubble number density are analyzed and the test results show that, in a stationary flow field, the influence on senktiefe of submarine-navigation is deeper as the bubble size is smaller, and an appropriate increase in the number density of bubble can significantly increase the senktiefe in a certain range. Research conclusion proves the feasibility and effectiveness of the artificial pycnocline technology of seawater density, which will provide a foundation and basis for further perfection of submarine military strike means and device development.
