法向發光強度-
The study is about a kind of 3 - year - old pharmaceutical plant t. media cv. hicksii. we set up 3 kinds of different illumination handles using the black sunshade net shading in the pharmaceutical plant garden of the southwestern normal university ( elevation is 250 meters ) of chongqing. the natural light intensity ( passing through light rate is 100 % ) is the contrast, consequently the passing through light rates of one - layer shading and two - layer shading are 50. 0 %, 12. 5 % respectively
本文以盆載(紫色壤土,盆高20cm ,直徑15cm ) 3年生的曼地亞紅豆杉( taxusmediacv . hicksii )為材料,于重慶西南師范大學藥用植物園內(海拔250m )利用黑色遮陽網遮光,設置3種不同的光照處理,以自然光為對照(透光率100 ) ,一層遮蔭、二層遮蔭透光率分別為: 50 . 0 、 12 . 5 。 -
However, the intensity gradient ( force ) of the diffracted light of the semi - gaussian beam is far smaller than that of the evanescent - light wave, so its spontaneous emission probability is greater than that from the evanescent - light one when the normal velo city of the incident atom is greater
然而,因為半束蘭失諧高斯光束衍射光場的強度梯度力遠小於消逝波光場,所以當入射原子速度較大時,原子在半束蘭失諧高斯光束衍射光場中的自發輻射幾率要大於消逝波光場。
