The present disclosure discloses a system and method for nonlinear damage compensation of a CO-OFDM transmission system, including: a radio frequency OFDM transmitter, the radio frequency OFDM transmitter performs modulation mapping on a signal to be transmitted, and sends the modulated and mapped signal to an optical I / O modulator; the optical I / O modulator converts the received signal from an electrical signal to an OFDM optical signal, and transmits the OFDM optical signal to the optical fiber link; each OPC optical phase conjugation device in the optical fiber link Coupling the signal and generating the opposite signal through the highly nonlinear optical fiber HNLF, thereby compensating the nonlinear damage of the optical fiber link; the optical fiber link sends the output signal to the optical coherent detector; the optical coherent detector detects the received signal Perform demodulation, demodulate the optical signal into an electrical signal, and send the demodulated electrical signal to the radio frequency OFDM receiver; the radio frequency OFDM receiver restores the received electrical signal.

The invention discloses a grinding wheel sheet with potassium-sulfur compound, which comprises a grinding wheel sheet base, on which a hexagonal shallow groove and a gear opening are processed, and the gear opening and the hexagonal shallow groove at the outermost edge Butt jointing; the grinding wheel sheet is further coated with a grinding wheel sheet resin layer, a potassium-sulfur composite layer and an abrasive layer in sequence. The invention aims at the problem that the instantaneous temperature of the traditional grinding wheel can reach 600°C when grinding the workpiece, which easily affects the damage of the workpiece and the damage of the grinding wheel itself. The melting point is only 480°C, which is enough to melt under high-temperature grinding conditions. At the same time, hexagonal shallow grooves and gear ports are processed on the grinding wheel, so that the molten liquid potassium-sulfur compound can seep out of the hexagonal shallow grooves. And from the gear mouth to the cutting edge of the grinding wheel, the temperature of the cutting workpiece is effectively cooled. The temperature is low and the cutting speed is fast, which greatly improves the cutting efficiency and shortens the cutting time.
