| 1. | If one of the bulleted points is missing , the answer can be given a maximum mark of 5 , i . e . low band 3
（如果答卷漏掉一个任务要点，最多只能得5分，即3档分数的下限。 |
| 2. | Attention ! repeated qso with the same participant is permitted on different bands and in each round of low band - part
注意!在别的波段参赛者可以在每回合的低波段进行重复的qso |
| 3. | Ionospheric effects ca n ' t be ignored if signals are at a low band and the bandwidth is large
结果表明，在信号频段较低、带宽较大的情况下，电离层的影响不容忽视，必须加以校正。 |
| 4. | Owing to high frequence , city power peak and pou can be removed by low band - pass filter that we design in the fourth chart
对于市电的尖峰和浪涌噪声，由于其属于高频成份，在本文第五章，我们设计了低通滤波器来滤波，消除其影响。 。 |
| 5. | Three salary bands , equivalent to the dollar terms of below mps point 10 lower band , mps points 10 - 33 middle band , and above mps point 33 - gds point 38 upper band , are used
相等于总薪级表第10点至33点所定金额的中层薪金级别，以及相等于超过总薪级表第33 |
| 6. | In the low band of wavelet transform , energy of ground roll wave is normally greater than the average energy in overall band of seismic reflection event , which is regarded as the discrimination criterion for it
在小波分频后的含面波频带内，同一时刻较强面波能量总要比该时刻全排列的平均能量大得多，这是分频识别强面波的判别准则。 |
| 7. | Feng yue ( signal & information processing ) directed by professor hong jun the propagation characteristics of signals will be seriously affected by the ionosphere , especially the signals having a low band and large wideband
电离层对星载sar特别是高分辨率、宽带sar的性能影响近年来已成为国际上的研究热点之一，目前我国在这一研究领域研究较少。 |
| 8. | The direct digital frequency synthesizer is a kind of fully digitized frequency synthesizer , which consists of the phase accumulator , the sine look - up table , the digital to analog converter and the low band filter . it is of high frequency resolution , fast frequency switching speed , low phase noise , the ability to switch frequencies while maintaining constant phase , and the ability to producing arbitrary waveforms
直接数字频率合成器是一种全数字化的频率合成器，由相位累加器、波形rom 、 d a转换器和低通滤波器构成， dds技术具有频率分辨率高、频率切换速度快、频率切换时相位连续、输出相位噪声低和可以产生任意波形等优点。 |
| 9. | The c of i submitted an interim report in november 1988 and a final report in march 1989 noting that the 1986 pay level survey did not provide a sufficient basis for making specific adjustments to civil service pay , and recommending that a revised formula should be used for future net pay trend indicators and adjustment for the lower band should be brought up to the level of the middle band should the former be lower
调查委员会先后在一九八八年十一月及一九八九年三月提交中期及最后报告，指出一九八六年薪酬水平调查结果，并未为薪酬的具体调整幅度提供有力依据。委员会并建议，日后计算薪酬趋势净指标时，应改用一个经修订的公式，而低层薪金级别的调整额如果比中层薪金级别低，就应调高至同一水平。 |
