Introduction Natural ecosystems provide the material base of the human survival and development.
The human take benefits directly or indirectly from ecosystem services, including useful material and energy to the economic and social system, acception and conversion of wastes from the economic process and direct provision of services to human society [1].A healthy ecosystem is the basic guarantee of the realization of human social and economic development [2].

Introduction Additive plays a key role in improving fuel quality.
The grey materials on piston crowns had been eliminated away, appearring a smooth surface.

By its own benefits, PID control is still has a long history and vitality strongest basic control mode in the field of control engineering [1].
Wind turbine is composed of the wind turbine and generator, wind turbine blade is the core of the most critical part, at present, the main material for the blades is glass fiber cloth [2].
PID Controller Structure Of Conventional Glass Fiber Textile In PID control system of glass fiber textile system, how to choose the proportional coefficient (P), integral time (I), derivative time (D) is the key to the design, Regardless theoretical calculation or engineering turning is unable to change the controller which was affected by poor performance and poor adaptability of operating conditions.
During the campaign, the ants will release a substance called pheromone on the path [11], and can sense the existence and strength of this material, and wove toward the place where pheromone is strength, to guide the direction of movement.

The raw materials of linseed and sunflower seed for the pressure infiltration experiments was taken as 30 g and 15 g.
Another reason is the degree of contact between the raw materials and the roller, which may influence the experiments at the condition of low pressure.

The Safety Monitoring Warning System of Mining Dump Truck Feng Qing-Dong1, 2, a, Shuai Jian1,b, Yin Yong-Jing2,c and Jiao Zhong-Liang1,d 1Faculty of Mechanical and Storage & Transportation Engineering.
Introduction The mining dump trucks are mainly used in large surface mines, and small amount of them used in large quarries and construction site, and match with the shovel loaders, electric shovel and excavators, roundtrip driving and transport materials such as minerals or coal, and it's the type of off-highway trucks [1].
According to statistics materials [2], each year, in surface mines and quarries, there is an average of five fatalities occurring in the world involving mining trucks, and the accidents that do not caused casualties, to caused damaged equipment and property losses are countless.
Although Caterpillar and Komatsu use DISPATCH real-time monitoring system, GPS, the key information and safety technology to develop intelligent unmanned mining dump trucks, and test run successful in some mines and the quarries, but because the technology remains incomplete and initial cost investment and daily maintenance cost is too expensive, so we has not use widely all over the world.
