a new method that dew point temperature and absolute humidity is jointly monitored is using in Liaoning power plant.

This paper has intruduced the design principle, functio n and performance index of the QJY-A type hydrogen humidity monitor and the appl ication for on-line measuring hydrogen absolute humidity of the hydrogen -coo led generator set in the generation station.

Corona onset voltage diminishes with the increase of absolute humidity and the decrease of relative air density.

Based on real time clock of GPS system,and by means of absolute time-marker,real time data acquisition between different sites was performed in the form of wireless.

As to the conservation of motion of center of mass, the method of absolute coordinate system is generally used in the teaching meterials of theoretic mechanics.

In this paper,absolute coordinates are used to define the position of each body,the kinematic joints between bodies and forces acting on or between bodies.
