With the rapid development of modern military science and technology, the support force of naval ship maintenance technology in various countries has shifted from shore-based and rear maintenance support to forward, maritime and mobile maintenance support. Important measures to restore the combat effectiveness of ships during naval warfare, deal with serious damage to ships in time, and ensure the vitality of ships. As an effective means to establish the technical support force for marine mobile maintenance, the mobile maintenance combined shelter can be installed on the requisitioned civil container ships during wartime to form a large repair ship for marine mobile support and provide marine relay-level maintenance support for the marine formation And repairs during wartime. A large number of pressure sensors, temperature sensors and liquid level sensors are installed in the ship's electromechanical equipment of modern ships. They play a huge role in the normal use of equipment, status monitoring, fault diagnosis, automatic control and safety alarms. Damage and the poor working conditions of the sensors themselves are likely to cause changes in their own characteristics or even failures. The test and detection cabins for sensor equipment should be established on large maintenance ships to verify various types of sensors and spare parts And calibration to meet the maintenance support requirements in wartime. The temperature sensor calibration test system uses a calibration furnace as the temperature source, and the temperature sensor to be calibrated and the precision temperature measuring resistor are placed in the calibration furnace at the same time. The temperature value output by the temperature sensor to be calibrated and the temperature value output by the precision temperature-measuring resistor are displayed on the main module of the calibration instrument to achieve comparative calibration. Due to the unique hysteresis of the temperature signal, it usually takes 1 to 2 hours to calibrate a temperature sensor. In order to reduce labor intensity and improve work efficiency, a temperature sensor with simultaneous calibration of wishing thermocouple and wishing thermal resistance can be selected.

The Ternary Lithium ion battery is a lithium ion battery using Ni-Co lithium manganate as the positive electrode material and graphite as the negative electrode material.
Ternary Lithium Batteries represent an important direction of current rechargeable lithium-ion batteries. In addition to Ternary Lithium Battery, the current market uses phosphorus Lithium iron battery, which is characterized with better safety for the domestic battery market mainstream products.
Ternary lithium batteries refer to lithium batteries containing transition metal lithium-intercalated oxides containing nickel, cobalt and manganese, which can be expressed as LiMnxNiyCo1-x-yO2 (0 < x < 0.5, 0 < y < 0.5). This material combines the advantages of lithium cobalt oxide, lithium nickel oxide, and lithium manganate, and forms a ternary synergistic effect of three materials, whose comprehensive properties are superior to any single combination compound. Weight energy density can reach 200Wh/kg
