When gasoline burns, gasoline and oxygen molecules combine to form new molecules . 當(dāng)汽油燃燒時,它的分子和氧氣分子結(jié)合起來,形成新的分子。
In respect of the auroral colour , oxygen molecules produce green and red colours while nitrogen molecules produce purplish - red and blue colours 氧能釋出綠光及紅光,氮則釋出紫紅色光和藍光。
In respect of the auroral colour , oxygen molecules produce green and red colours while nitrogen molecules produce purplish - red and blue colours 氧能釋出綠光及紅光,氮則釋出紫紅色光和藍光。
Ultraviolet rays from the sun decomposed into atomic oxygen molecules into the atmosphere at the highest level ( the ionosphere ) the main ingredients 來自太陽的紫外線把氧分子分解成原子,成為了大氣最高層(電離層)的主要成份。
When we conduct experiments using nickel or cobalt sulfides , we see that carbon addition occurs primarily by carbonylation ? the insertion of a carbon and oxygen molecule , or carbonyl group 要是我們以鎳或鈷的硫化物做實驗,增碳過程主要循羰基化途徑進行,也就是塞入一個羰基(由一個碳原子、一個氧原子組成) 。
The hematoporphyrin sensitizer used in photodynamic therapy produce toxic substance through translating energy to oxygen molecule , so the distribution of oxygen in tissue have special value as there has consumption of oxygen during photodynamic therapy 光動力療法使用的葉琳類光敏劑主要是通過將能量轉(zhuǎn)移到氧分子產(chǎn)生單線態(tài)氧來產(chǎn)生毒性物質(zhì),因此在光動力治療中有氧的消耗,使組織中氧分布對光動力作用具有特殊意義。
Elastic collision and inelastic collision are considered in oxygen molecule , nitrogen molecule by electron impart . the mail simulation results were as follow : ( 1 ) the variations of drift velocity and the average energy of electron with the e / n in o2 and n2 are obtained . the number of electrons for excitation , ionization , dissociation and dissociative ionization collision with the e / n and the energy of electron are analyzed emphatically 考慮了各種彈性和非彈性碰撞過程,在純氧氣、純氮氣中,給出了不同簡化場e n條件下的電子漂移速度和平均電子能量的變化;著重分析了激發(fā)、電離、分解及分解電離碰撞的粒子數(shù)隨e n 、電子能量的變化,同時計算了激發(fā)發(fā)射光譜的波長。
