Two 15nt complementary ssDNA primers were ligated into double stranded satRNA.Complete sequence of satRNA was obtained by RT-PCR using these 15nt ssDNA as amplification primers.Phylogenetic analysis showed that the identity of this 383nt satellite and some documented satRNAs was 72.6 to 99.5% at the nucleotide level.

以常规引物对感病植物的总RNA进行RT-PCR扩增，获得CMV RNA3全长克隆，经测序显示该RNA3序列属于CMV亚组Ⅱ；通过在卫星dsRNA两端分别加上15nt的单链DNA接头，以接头互补序列为引物进行扩增获得一个383nt的卫星RNA的全长序列。

Moreover, the IGBT radio frequency amplification phenomena, can become relevant if the driver circuit generates high frequency conducted noise components, that can be transferred to the final stage and amplified, generating very high EMI levels.

此外，如果驱动电路产生的高频传导噪音被放大传递到末级，相应的IGBT射频放大现象可以产生更高的EMI。
