非整倍體種 的英文怎麼說
中文拼音 [fēizhěngbèitǐzhǒng]
非整倍體種
英文
dysploidion-
An aneuploid state in which a third homologous chromosome is present in addition to the normal autosomal pair is called trisomy.
除了正常染色體對以外,還存在有第二種同源染色體的非整倍體狀態,被稱為三體性。Based on these foundations, we give a perfect scheme of the bbo opos : single pass amplification coefficient of the opg under different pump intensity is calculated ; collinear type - i and type - ii phase matching tuning curve pumped by the q switch nd : yag various harmonics as well as noncollinear type - i tuning curve are calculated in details ; the effect of the walkoff for the nonlinear effect coefficient and the group velocity matching are analyzed ; the acceptance angle in parametric process is calculated ; the numerical threshold of the bbo opo is calculated ; the process of the saturation and depletion of the pump beam are analyzed ; the relationship of the conversion efficiency and reflectance of output mirror are discussed ; various linewidth controlling methods are discussed ; the improvement of the beam quality applying the unstable cavity is discussed ; and the crystal bbo design is considered
在此基礎上,給出了一整套bbo - opo激光參數設計方案:計算了不同泵浦強度下的參量放大倍數;詳細計算了在nd : yag調q激光器各次諧波泵浦條件下的共線類和類相位匹配的調諧曲線,以及非共線類相位匹配調諧曲線;分析了走離角對非線性系數和群速匹配的影響;計算了參量過程的允許角;計算了bbo - opo的理論閾值條件;分析了飽和與泵浦光束的消耗過程;給出了轉換效率與超過泵浦閾值的倍數的關系;討論了轉換效率與輸出鏡反射率的關系;討論了線寬控制的各種方法;研究了利用非穩腔改善光束質量的方法;考慮了bbo晶體的設計。
