氦離子在添加倍頻光的雙色場(chǎng)作用下高次諧波產(chǎn)生效率極大提高的原因是：倍頻光極大地加快了電子電離到連續(xù)態(tài)及返回基態(tài)這一過(guò)程夜恋午夜成人影院在线播放网站，使輻射出的高次諧波光子數(shù)大大增加人妻系列少妇人妻AV无码，該初步闡釋可為高次諧波真正應(yīng)用到實(shí)際中提供一些理論啟示乐播三级黄三区视频免费。

Photosynthetic traits of Ningai 1 and its 4B-monosomic, nullisomic line were investigated in this paper(Rht3 gene was located in 4B-chromosome). 4B-chromosome has the positive effects on photosynthetic rate, chlorophyll content, RuBP carboxy lase content and activity, leaf conductance, chlorophyll relatve steady phase and photosynthetic avtive duartion and these effects are accumlative. So 4B-chromosome has the promoting influence on photosynthesis.
