What clued researchers in was when a diver thought someone was giving him underwater directions, telling him to get out of the tank.

给了研究人员提示的是一个潜水员认为有人在给他水下指引让他从水池里出来。

Tank filled with water for keeping fish and underwater animals. found in still or slow-moving fresh or brackish water; useful oxygenator for cool water ponds and aquaria.

生长于静止的或缓慢流动的淡水或微咸的淡水中；对于冷水池塘和养鱼缸来说是一种有用的充氧器。

The experimental results shows that optimal results of an underwater towed system test conducted in a model ship towing tank can be achieved with the technique. The method provides an ideal means for laboratory experiments on an underwater towed system.
