进入20世纪90年代以来，我国海水网箱养殖发展迅速，产生了显著的社会经济效益。为避免这些自然灾害的损失及环境污染，使目前通常采用打桩固定或开发深水网箱的方式加以解决，所以就提出了对网箱水上航行移位和水下升降调节的机理进行研究，在此基础上提出螺旋桨驱动网箱水上航行和水下升降调节的控制方式，为可移位航行式网箱开发应用提供依据。%Since the 1990 s ,the seawater aquaculture has developed rapidly in our country ,has a significant social and economic benefits in order to avoid the loss of natural disasters and environmental pollution ,make the cur-rent usually adopt the way of piling fixed or developing deep -water cages to solve ,so he proposed to the sailing area water displacement and underwater lifting adjusting mechanism is studied ,based on this ,advances the pro-peller driven caged Marine navigation and underwater lifting adjusting control mode ,provide the basis for sailing can shift type area development and application .
