常見例句雙語例句Itspulse repetition frequency was 81.脈沖重復(fù)頻率平均為81。For improving the SNR and the reducing transmit power of the SAR simultaneously, airborne SAR often use high PRF (Pulse Repetition Frequency).機(jī)載SAR為提高信噪比并同時減少發(fā)射功率,往往使用較高的脈沖重復(fù)頻率(PRF)。Ultrasound-assisted gene delivery is associated with the parameters of ultrasound exposure, such as mechanical index, pulse repetition frequency, time of exposure, and so on.超聲的此種特性,與超聲的照射條件,如機(jī)械指數(shù)、脈沖重復(fù)頻率、照射時間等有關(guān)。 返回 repetition frequency
