interference n. 1.沖突,抵觸。 2.干涉,干預(yù)。 3.妨礙,打擾,阻礙物。 4.【物理學(xué)】干擾;干涉。 linguistic interference本族語對外語學(xué)習(xí)的干擾。 stop interference from outside 制止外來干涉。 run interference for (橄欖球賽中)保護(hù)(帶球者)以防對方搶球。
This situation is called constructive interference . 這種情形稱作相長干涉。
Since these two electric fields must be in phase at point p for constructive interference to occur , the arguments of the sine functions must be equal 由于兩個電場在p點(diǎn)必須同相以獲得相干,這兩個正弦函數(shù)必須相等。
In this paper we have done two work , one is we , in the dressed states representation , reveal that the constructive interference of atomic coherence on absorption leads to electromagnetically induced absorption , which is in sharp contrast to the case in which destructive interference of atomic coherence gives rise to electromagnetically induced transparency and the other is we reveal that coupling field linewidth inhibits electromagnetically induced absorption , by employing a four - level system in which three transitions are in n configuration and the middle transition serves as a probe transition 本文主要做了兩方面的工作:一是在修飾態(tài)表象中揭示修飾態(tài)原子相干對吸收的相長干涉產(chǎn)生電磁誘導(dǎo)吸收,這與修飾態(tài)原子相干對吸收的相消干涉導(dǎo)致電磁誘導(dǎo)透明的情形形成鮮明的對照。二是在裸態(tài)中,引入耦合場的線寬,從而發(fā)現(xiàn)耦合場的線寬抑制電磁誘導(dǎo)吸收。首先研究電磁誘導(dǎo)吸收。
