在美国马萨诸塞州伍兹-霍尔的一个工业库房里,一只毛绒玩具犬守卫在一只重达五吨的钛制球体旁边。这个直径2.2米的球体明光锃亮,反射着来自头顶的灯光和从旁边走过的科学家的脸庞,他们来此亲眼目睹这个价值1100万美元的工程奇迹,一个足以将研究人员运送到6500米深海海底的球形载人舱。该球形舱将成为美国深海探究领域的生力军阿尔文号潜水器的新心脏。 In an industrial warehouse in Woods Hole, Mass., A plush toy guard stands beside a titanium ball weighing five tons. The 2.2-meter-diameter sphere, bright and clear, reflects the light from the overhead and the face of the scientist passing by. They witnessed this $ 11 million engineering miracle, one enough to transport researchers to the deep sea of ​​6,500 meters Spherical manned cabin. The spherical capsule will be the new heart of the Alvin SSW submarine, the new force in deep ocean exploration in the United States.
