In this paper, fuzzy AHP to select the appropriate environment-friendly chemical mechanical polishing additives, and the rational design of the polish formulation. Practical application shows that the polish has a good anti-wear, the wear properties and anti-rust properties, stable performance ，and meets the needs of the chemical mechanical polishing, the rate of biodegradation more than 80%.

This article combines with the engineering machinery of diesel engine, the hydraulic system, the gear system, the hydraulic transmission system using oil of performance requirements; in order to meet the need of engineering machinery actual using condition. Through the study of base oil, antioxidant and corrosion inhibitor, detergent and dispersant additive, extreme pressure and anti-wear agent, rust inhibitor, anti-emulsifier, anti-foam agent, etc composite additives. using Poly-α-olefin (PAO) and dioctyl sebacate composite act as the engineering machinery general oil of base oil, and by using the artificial neural network algorithm targeted to a variety of the functional additive of screening and prediction, and using the genetic algorithm optimists the selection of formula, develop the environment-friendly and energy-saving engineering machinery general oil.

In this paper, through the study of the marine conditions of structural facilities applications, in order to reduce the corrosion of marine structural facilities, Asked the neural network algorithm combined genetic algorithm to determine the components of the coating to the development of composite scales heavy anti-corrosion coatings, it has interpenetrating polymer network structure (IPN). Experimental results show that the composite scales heavy anti-paint adhesion, excellent corrosion protection, easy to use marine engineering, field operating conditions used, and its sources of raw materials widely,modulation process is simple, easy to mass production and application, can be reduced to some extent marine the cost of structural facilities for anti-corrosion.

The combination of ship gas turbine working at special environment, this article pass through the study of base oil and composite additive, developed an application marine environment of the ship gas turbine reducer lubricants. According to comprehensive performance assessment, the product has excellent high-temperature anti-oxidant, anti-wear, corrosion inhibition and anti-foam performance. The indicators have reached the requirements. With the development of China's ship gas turbine technology, especially UGT25000 ship gas turbine technology is imported from Ukraine, as well as the recent introduction of the GE LM2500 + G4 Series of technology for power plant of construction. The localization of the supporting facilities are growing louder, there is a strong market rigid demand. Ship gas turbine must be one of the trends of the development of Marine Power. Ship gas turbine due to light weight, small size, stand-alone power, fast start; less pollution, vibration, high thermal efficiency and gas initial temperature, it is easy to realize the cascade of energy use, economy, received widespread attention and application. China's ship gas turbine of modification and design draw the aero-engine, ship gas turbine is a continuous rotation of the impeller mechanical heat engine; it is mainly composed by three parts of the compressor, gas generator and gas turbine. Ships generally use diesel (fuel have heavy trend, the heavy diesel oil or No. 200 heavy oil will be used) as fuel, in order to adapt the ship gas turbine, ship gas turbine need to transform, particularly its' lubrication system [1]. Foreign aviation gas engine lubricants are based on the U.S. standard as a reference, due to the differences of using purpose and fuel, so that the ship gas turbine oil has different requirements. Since ship gas Turbine Technology started late in China, the ship gas turbine core engine technology patents come from the United States, Russia and Ukraine, so the use of gas turbine lubricants, as well as matching accessories and other standards, which are more or less directed reference to refer to the original foreign standards [2,3]. We have never been established using standard ship gas turbine oil. Ship gas turbine apply to the special conditions (high humidity, salt spray, etc.), the ship gas turbine of lubrication has a higher demand, particularly for the ship gas turbine reducer of lubrication. The ship gas turbine reducer work in the low-speed heavy-duty and high-speed heavy-duty , high strength, high shear conditions, how ensure the ship gas turbine reducer to normal work is very important at high load conditions. In this regard, developing of a ship gas turbine reducer lubricant is very necessary.
