英文摘要： Pressure balance and pressure detection of sensor in deep ocean environment is the basic issue and key technologies in the area of ocean monitoring and ocean engineering.Currently the investigations on the principles of mechanics and mechanical behavior of the pressure balance methodology in deep ocean environment is insufficient, and the required wide range detection and high sensitivity for deep ocean pressure probing remain two big obstacles. Our project aims at exploring the mechanical properties of pressure balance by using the elastic components (diaphragm, soft bladder.capsule and bellows) and the piston in the deep ocean. Based on the compressibility of the liquid, the influence of the pressure difference inside and outside of the sensor on the sensor performance and measurement accuracy caused by variational water pressure with depth is investigated. The characteristics of various pressure balance methods under the big pressure of the deep ocean environment as well as the design principles of the pressure balance device are summarized. In order to meet the requirement of the ocean monitoring, scientific research and deep-sea resources exploration, the high-precision pressure detection approach is studied, and the design approach of reliable and low-cost new ocean pressure sensors is investigated.
