暗發射體 的英文怎麼說
中文拼音 [ànfāshètǐ]
暗發射體
英文
dull emitter-
Green fluorescent protein ( gfp ) gene was conjugated to the 3 " end of the pap gene in order to screen easily of the transgenic cotton plants. the combined gene was cloned into plant expression vector pbi121 and then transformed. about 5000 seeds of the transgenic cotton were obtained and the some seedlings of the transgenic cotton could give a bright green fluorescence in the dark condition when the cotton seedlings were irradiated with ultraviolet rays
為了便於轉基因棉花後代的篩選，在pap基因的3 』端融入了綠色熒光蛋白gfp ）基因，然後將融合基因克隆在植物表達載體pbi121上，再進行遺傳轉化，得轉基因棉花種子5000餘粒，將種子播種長到于葉展開時，先在黑暗中用紫外燈照射，查找表現綠色熒光的幼苗，然後再用地高辛（ dig ）標記的pap基因特異性探針對這些棉花進行點雜交，最後發現有8株棉花表現陽性反應，說明pap基因的確己經轉到了棉花的基因組中，其棉花黃萎病的抗性鑒定正在進行之中。It is found that the fwm field can cause the asymmetry of electromagnetically induce transparency profile. in addition, the effect of different propagating orientations of probe field on the electromagnetically induced transparency is also discussed. in the molecular multi - level system with the perturbed superposition levels, we discuss the electromagnetically induced transparency, spontaneous emission enhancement, double dark resonance and double electromagnetically induced transparency by using the density matrix equation under weisskopf - winger approximation and dressed - state density matrix equation
針對實際的實驗條件，考慮了一種影響量子干涉的新的因素-四波混頻場，研究了四波混頻場對雙光子探測的-型能級體系的eit的影響，發現四波混頻場能夠導致雙光子探測的eit線型的不對稱，在此基礎上，討論了不同探測場的傳播方式對eit的影響，針對分子中實際存在的包含有微擾能級的不同多能級系統，我們分別採用綴飾態繪景下的密度矩陣方程和weisskopf - wigner近似下的密度矩陣方程詳細地討論了電磁感應透明、自發輻射的干涉相消和相長、雙暗態共振和雙電磁感應透明現象。
