相对吸收强度
相关语句
  relative absorption strength
     Compared with the spectra in neutral solvent such as cyclohexane, the spectra in some Lewis basic solvents were red shifted, and the relative absorption strength ratio of α band to β band decreased. The spectral changes may be due to the axial coordination of these solvents with the vanadium in VOOEP and the nickel in NiOEP.
     结果发现 ,两种金属卟啉可以与一些Lewis碱性溶剂发生轴向配位作用 ,形成轴向加合物 ,加合物的紫外可见吸收光谱红移 ,α和β吸收带的相对吸收强度比减小 ;

The fluorescence studies on high-Tc superconductors YBa2Cu3Ox (I) and have been carried out at 77K and 298K. A broad emission band at 390nm is observed in both systems. The excitation spectra of them have also been determined.

本文分别在室温和液氨温度下,测定了高Tc超导体YBa_2 Cu_3 O_x和YBaCu_2O_x的UV激发荧光光谱。所观察到的位于390hm左右的宽发射峰与X-光激发荧光光谱的结果相吻合。激发光谱出现了246nm、275nm和308nm三个峰,它们的相对吸收强度和温度的变化有关,初步认为这一现象可能与超导性质存在者一定的关系。

An experiment of isolating lignin from bagasse raw materials, bagasse sulfite chemimechanical pulp and its spent liquor with cresol and sulfuric acid was carried out. Comparisons were made in respect to dioxane lignin. It is evident that using cresol and suffuric acid to separate lignin is an effective method not only from the raw material and pulp, but also from the spent liquor. The study also indicates changes in the properties of lignin in the pulp and the spent liquor such as lignin yield, molecular weight...
