收發信機 的英文怎麼說
中文拼音 [shōufāxìnjī]
收發信機
英文
tra ceiver-
That is, if we want to assign frequencies to a pair of adjacent cities or radio stations, then the difference of those two frequencies used has to avoid the set t. the t - colorings of multigraphs is a more practical case of t - colorings of graphs where interference may occur on different level
頻率分配問題的圖論模型可以這樣得到：令收發信機為圖中的點，兩點之間有邊當且僅當這兩個收發信機干擾。重圖的t -染色是圖的t -染色的一個較為實用的部分，這是因為在研究頻率分配時，干擾可能會在不同的水平上發生。The power line carrier transceiver dedicated to protection
