A self-evolutionary compensation approach was developed to reduce the crossbeam deformation induced by the gravitational force on a large numerically controlled gantry milling machine.

Intelligent controller of power-factor automatic compensation based on PIC single chip;

Study of automatic compensation on the braking device of Down Belt Conveyor;

Generally support the water pressure adjustment and automatic compensation that strength can't according to mine well downfeed systems.

In the Presented paper the uncertainty caused by measure principle of the cylinder method for measuring the thermal conductivity of thermo-insulating materials with heating of self-compensation is analyzed with a numerical method.

A self-compensation method is proposed based on digital closed-loop control technology that eliminates the influences of the factors such as working conditions,circuitry parameters and so on.

Based on a self-compensation model involving the deep donor MGaVN,we calculate the hole concentration as a function of magnesium doping concentration NA,w.

To evaluation self-compensation situation of township hospitals poverty areas, put forward a proposal and strategy on developing the management of hospitals in villages and towns and improving the economic benefits.
