零聲子線 的英文怎麼說
中文拼音 [língshēngzixiàn]
零聲子線
英文
zero phonon line-
The isoelectronic system of gap : n has been investigated extensively in the dilute limit since 1965. thomas et al identified that a series of sharp emission lines in gap : n were due to the recombinations of excitons bound to either isolated nitrogen centers or various nitrogen pair centers
這些譜線來自於等電子雜質n形成的束縛激子態（孤立n中心和nn _ i對）輻射復合產生的零聲子線及其聲子伴線。When x is above 1. 3 %, the emission spectra are strongly broadened and do not show any well - defined features, and their peak positions shift to lower energies correspondingly with increasing x. the large band - gap bowing of gap1 - xnx alloy is induced by the impurity band formation due to the intercenter interaction
對中心發光的nn3束縛激子的零聲子線及其聲子伴線，並得到了nn3的所有聲子伴線（ l0 、 la 、 ta ）的s因子在約20k卜50k范圍內與溫度的關系。The research results are controlled source which has linear or nonlinear variabe frequency scan function and the seismic instruments which match with it, and the method of small group intervals, small offset, much more channels, short array length, high - frequency receivers are applied during the link of data acquisition, and that the techniques of the refraction static correction, the noise suppressing, the high - resolution velocity analysis, the wavelet length compression, the wavelet zero - phase, and the prestack migration should be applied emphasizedly during the link of data processing and interpretation
研究表明，對于城市活斷層的抗干擾高解析度淺層地震勘探，在數據採集環節應採用具有線性或非線性變頻掃描功能的可控震源和與其相匹配的地震儀器，以及小道間距、小偏移距、多接收道、短排列和高頻檢波器接收的工作方法；在數據處理與解釋環節，要重視折射靜校正技術、噪聲壓制技術、高精度速度分析技術、子波壓縮技術、子波零相位化技術和疊前偏移技術等的應用。
