A digital saw-toothedWave generator adjustable frequency and amplitude is introduced in the paper, and gives the realizing method as well as actual circuit.
The seal principle and its constriction of H-type complex gasket were introduced, as compared with wave-toothed compound gasket and spiral wound gasket.
