同学们,你们知道潜艇吗?这可是一条“水下巨鲸”啊!它会无声无息地呆在水里,并悄悄地靠近敌人;更厉害的是,它能够从水下发射弹道导弹,直接打击目标。我国的海军已经建立了强大的核潜艇队伍,大大增强了海防能力,威慑了敌人。潜艇威力无比,但你知道它是怎样在黑乎乎、听不到远处声音的海水里判断敌人的方向,攻击敌人吗? 告诉你吧:声呐装置就是潜艇的耳朵,没有了它,潜艇在海里不但威慑不了故人,而且还可能成为被攻击的对象。所以说,这些拥有核潜艇的国家都花大力气研究先进的声呐系统。我国也不例外。我们这期介绍的科学家,就是研究声呐系统的李启虎院士。
Students, do you know the submarine? This is a “underwater whale”! It will silently stay in the water, and quietly close to the enemy; even worse, it can launch ballistic missiles from underwater, Directly hit the target. Our navy has established a strong contingent of nuclear submarines, which has greatly enhanced our coastal defense capability and deterred the enemy. Submarine is extremely powerful, but you know how it is in the dark, can not hear the voice of the distant water to determine the direction of the enemy, attack the enemy? Tell you: the sonar device is the submarine’s ear, without it, the submarine The sea not only deter the enemy, but also may be targeted. Therefore, all those countries that own nuclear submarines have devoted great efforts to studying advanced sonar systems. My country is no exception. The scientist we introduced in this issue is Academician Li Qihu who studies the sonar system.
