摘要：
It is pointed out that the principal advantages of the pyroceramic scribing operation are due to the use of pulsed lasers, operating with short-duration, high-frequency pulses. An experimental investigation of the conditions for the working of the pyroceramic plates with a 0. 5 mm thickness showed that for a heat flux density of q equals 5 multiplied by 10**4 W/cm**2 and a velocity of v equals 0. 5 cm/sec for the heat source the crack forms spontaneously and proceeds along the delineated scribe. By cleaving the plates along the scribe it is possible to produce surfaces with a complicated shape.
