频率带 meaning in Chinese
band of frequencies
bandoffrequencies
frequency band
frequency zone
Examples
- In very small amounts throughout the eons were these frequencies of information brought onto this planet
以少量的全部永世就是把这些频率带到这个行星上。 - Satellite earth station and systems - television receive - only satellite earth stations operating in the 11 12 ghz frequency bands
卫星地面站和系统.在11 12ghz频率带范围操作的只接收电视的卫星地面站 - Fixed radio systems - point - to - point antennas - antennas for point - to - point fixed radio systems operating in the frequency band 3 ghz to 60 ghz
固定无线电系统.点对点天线.在频率带3ghz - 60ghz范围内操作的点对点固定无线电系统 - The properties of spontaneous emission depend not only on the relative position of the resonant frequency from the edge of the photonic band gap and the photonic mode density but also on the relative distance of the atomic space position from the sidebrand . and we study other property of spontaneous emission
其性质除了依赖于原子上能级与光子频率带隙边缘的相对位置或光子态密度，还依赖于原子的空间位置与侧支距离。并对原子的自发辐射的其它特性进行了分析。 - In addition , the control of spontaneous emission of a three - level atom embedded in photonic crystals was investigated in this paper , because the model of two - level atom is siple . as it shows , the properties of spontaneous emission depend not only on the relative position of the resonant frequency from the edge of the photonic band gap and the photonic mode density but also on the intial atomic state
二能级毕竟是最简单的模型，故在最后，还对光子晶体中三能级原子的自发辐射特性进行了研究。结果表明，其自发辐射除了依赖于原子上能级与光子频率带隙边缘的相对位置或光子态密度外，还依赖于原子的初始状态。
