The key technical measures for obtaining high stability of the power supply are introduced.

it has the high stability signal sweep frequency using the phase-lock link to carry on to the digital quantity reading,through D/A transformation,the appropriate filter may obtain the high stability signal output.

The amplitude of output harmonic is a very important to reach high stability in a current source.

The high and stable yield characters of the oil rape varieties past in regional trials of Sichuan Province in 1995～1997 were analysed with high and stable coefficient(HSC),and in the mean time, a comparison and correlative analysis between the result and that obtained by statistical analysis in common use were conducted.
