The deep science and technology project was inspired by the "dragon". The jiaolong sea trials at level 5000 m and 5000 m level invited during sea trials Please try the Marine scientists involved in the sea process, fully tap the latent time the scientific value of each test, let volunteers engineers realized the benefits of scientists and engineers are closely combined. , on the other hand, from the United States in 2010 to commemorate the human in order to the marianas trench Deep - "challenger deep" writing in the 50th anniversary of the memorial of awareness of the deep science and technology is the forefront of science and technology in the field of ocean.
