直接放大 meaning in Chinese
direct amplification
straight amplification
Examples
- We built a table - top ultrashort laser system which based on ti : sapphire front - end and discharge pumped krf amplifier . with double pass off - axis amplification module , the imj uv pulse was amplified to 50mj
建立了桌面krf超短脉冲激光系统，采用放电泵浦krf准分子激光放大器进行超短脉冲激光的直接放大。 - Raman fiber amplifier （ rfa ） is a kind of optical amplifier that can amplify signal light directly through nonlinear interaction of high intensity pump and signal light in fiber . whereas the spectrum of raman gain coefficient of optical fiber is not flat , the gain of signal light with different wavelength induced by a single pump is rather different , when wavelength division multiplexing ( wdm ) signal light is amplified by a single pump , the gain spectrum of the wdm signal light is not flat . the flatness of the wdm signal light has important impact on the optical signal - to - noise ratio ( osnr )
拉曼光纤放大器（ ramanfiberamplifier ,简称rfa ）利用高强度的泵浦光与信号光在光纤中的非线性相互作用实现信号光的直接放大，但是由于光纤的拉曼增益系数谱很不平坦，所以同一泵浦光源对不同波长信号光的增益就存在很大的差别,因此,用单泵浦光源来放大波分复用( wavelengthdivisionmulti - plexing ,简称wdm )信号光时，各信号光的增益值就有很大差异， wdm信号增益的平坦度对光信噪比( opticalsignal - noiseratio ,简称osnr )有重要影响。 - From some characteristics observed , such as the short lift time , narrow frequency band , fast frequency drift , quasi - periodic pulsation , spike event and complex magnetic structure , it is considered that the radiation mechanism of these events may be principally due to the electromagnetic waves magnified directly by the instable electronic cyclotron
从它们的观测特征：短寿命，窄频带，频率快速漂移，及尖峰事件与磁结构复杂的大黑子活动区密切相关等，认为这些事件的辐射机制可能是电子回旋脉泽不稳定直接放大电磁波所致。
