  4. As the test signals of the trial will be transmitted via channels 35 and 37 ( never been used before to transmit television signals ), thus the television antenna systems using the said channels or the adjacent channels 34, 36 and 38 for other usages, such as the video cassette recorder ( vcr ) channel or closed circuit channel, might encounter interference during the said period

    是次測試使用的第35及37頻道，由於以往未有用作電視訊號發射，故任何電視天線系統如透過以上頻道或相鄰頻道（即34 、 36及38 ） ，作其他用途，例如用作錄影機播帶頻道，保安攝影機頻道等，將可能受到干擾。
  5. Pulsar radio emission is markedly different from other astrophysical radio sources, characterised by extremely high brightness temperature and high degree of linear or circular polarization. the high brightness temperature of the pulsar radio emission implies that the underlying emission mechanism must be coherent. so far there is no widely accepted model for the radio emission. this paper discusses recent developments in studies of the production and propagation of pulsar radio emission
