查询词典 spontaneous emission

However, operating of the high current, the output power, gain, and efficiency of gyro-TWT will be degraded where the absolute instability, gyrotron backward oscillation and reflective oscillation occur to cause mode competition. Stability issues comprise the key factors limiting the performance of the gyro-TWT, therefore physical origins of spontaneous oscillations in the gyro-TWT are analyzed and characterized.
