| 1. | Analysis of the unbalanced sidebands of phase modulation
相位调制边带失衡问题研究 |
| 2. | In digital communication , a transmitted carrier signal that consists of the12 single sidebands being sent over the transmission circuit
在数据通信中，一种传输载波信号，由传输电路上发送的12个单边频带组成。 |
| 3. | Also , the different temperature dependence between the sidebands of nni and the zero phonon line indicates there might exist other n impurity states
或许正是这些杂质态的存在，降低了样品的热激活能。在组分从x = 0 . 24 %到x绍 |
| 4. | With increasing x , the intensities of the deep nni centers and their phonon sidebands become enhanced and their pl linewidths gradually broaden and shift to lower energies
一方面，得到了gapi . xn :混晶从低n组分下的nn .对中心的发光到高组分下形成杂质带的演变。 |
| 5. | In order to meet the demand for smaller capacity and high rejection in upper - sidebands , the sir ( step impedance resonator ) structure has been used as the construction of the resonator in the filter
滤波器采用sir ( stepimpedanceresonator )结构,实现了滤波器的小型化、较好的带外抑制和高选择性。 |
| 6. | Theoretical analysis and simulation results demonstrate that asymmetries in lower and upper sidebands and imd magnitude variation depending on envelope frequency and junction temperature can appear , these results are in accordance with measurement results , and show that electrical and thermal memory effects exist
理论分析和仿真结果表明功率放大器上下边带不平衡和互调失真幅度依赖于包络频率和结温，结果和测量的结果是一致的，说明存在电和热记忆效应。 |
| 7. | The investigation of the exciton - phonon coupling of nn3 center offers a direct proof that all the phonon replicas are the phonon sidebands governed by the huang - rhys " multiphonon optical transition theory , and clarifies the speculations that the replicas associated with optical phonons are independent bound states of exciton - phonon complexes or due to other alternative mechanisms
对其变温pl谱的研究还发现，在nn :的声子伴线区域呈现出的异于多声子光跃迁理论的现象，说明在该区域可能存在着其它的n杂质态。 |
