例句
- The second harmonic three-stage gyroklystron amplifier is designed and simulated by means of PIC simulation software.
應用粒子模擬軟件對設計的二次諧波三腔回旋速調管放大器進(jìn)行了數值模擬。 - The result indicates that ionization probabilities of small clusters are less than that of atoms, and can produce high frequent harmonic.
結果表明，當外場(chǎng)強度相同時(shí)，小尺寸原子團簇電離幾率小于原子的電離幾率，可以產(chǎn)生高頻率的高次諧波。
