| 3. | Magnetotelluric sounding whole frequency bands migration imaging versus inversion technique 大地电磁全频段偏移成像结合反演技术 |
| 4. | Thus a completely numerical compute analysis method is established in fluid about vibrational radiation efficiency at full frequency 从而建立一套圆柱壳体在流场中振动声辐射效率在全频段的数值计算分析方法。 |
| 5. | We also design the approach to evaluate the errors from the imaging result and thus eliminate them 在此基础上研究基于图像数据的运动补偿,对成像结果中的误差进行估计与补偿,以多途径全频段地消除相位误差的影响。 |
| 6. | At the same time , we have manufactured a transition from microstrip line to rectangle waveguide , working in full ka - band . the insert loss of a single transition is between 0 . 25db and 1db 同时,完成了ka全频段微带波导过渡的研制,在26 . 5 39 . 5ghz频率范围内,单个微带波导过渡的插损在0 . 25 1db |
| 7. | The investigation is very useful not only in further studying the electromagnetic scattering characteristics of complicated large objects over the whole frequency band , but also in improving and designing the wide - band radar , ultra wide - band radar and new wide - band radar absorbing material 本文的研究,为今后进一步开展复杂电大目标全频段电磁散射特性的研究提奠定了基础,为宽带雷达和超宽带雷达的设计与开发,新型宽频带隐身材料的研究提供理论指导。 |
| 8. | Their input and output lines should be decoupled at all frequencies , they should be shielded to prevent external electric and magnetic fields from causing interference , and they should be sited as far as possible from sensitive circuits so that residual electric and magnetic fields are prevented by distance from doing serious damage 开关电源的输入输出线必须进行全频段去耦处理;要借助屏蔽手段抑制电、磁干扰;开关电源要尽可能远离小信号电路,确保其电磁场对模拟电路影响最低。 |
| 9. | In recent years , radio technology has developed very quickly in our country . however , a radio monitoring receiver with broad frequency scale ( 20 - 3000 mhz ) , high scanning rate ( above 1ghz / s ) and whole spectrum real - time display has not developed . some imported monitoring receivers with broad frequency scale can only scan slowly and could n ' t meet actual needs . not only these imported receivers " price is high but also those developed countries usually limit the quantities of imported receivers and related technology is not open 近年来我国无线电技术水平已经有了很大发展和进步,但对于频率覆盖范围宽( 20 - 3000mhz ) 、扫描速度快( 1ghz / s以上)并具备快速全频段实时频谱显示和记录的无线电监测接收设备,目前我国尚不能生产,国内现在已经进口的宽频段监测接收机一般也只能进行低速扫描,无法满足实际的需要。 |
