摘要: 本文提出两条等价性定理,用来判别不同排列的相位循环是否等价。又提出一种新的设计相位循环的方法-脉冲单元法,克服了由多线相干转移路径引起的多值性困难。

关键词: 相位循环, 等价性定理, 脉冲单元

Abstract: Two equivalent theorems are presented which judge whether phase cycles of different arrangements are equivalent. A new method of pulse unit for the design of phase cycles is also presented which overcomes the difficulty of multiple-yalue arising from donble coherce-transfer pathways.

Key words: Phase Cycle, Equalent corem, Pulse Unit
