The aim of this study is the optimization of Er3+ doped laser glasses which are used for the realization of high power laser amplifier and fiber laser. The Er3+ doped cadmium silicate glasses were fabricated by the technique of high-temperature melting. The emission intensity of 1534 nm near-infrared light pumped at 488 nm, 532 nm and 800 nm laser were compared. The spectral parameters were determined...
Based on the literature review and analysis, the paper constructs an evaluation index system of enterprise technology innovation and ecologicalization, uses the gray correlation method and information entropy to calculate the correlation between technology innovation and ecologicalization level in the pharmaceutical manufacturing field. The finding is that enterprise ecologicalization level most linked...
To overcome the low efficiency of phosphorus removal in the continuous influent biofilm, the continuous influent biofilm reactor (CIBFR) which based on intermittent aeration, rich phosphorus wastewater return and commutative influent was proposed in this study. The effects of dissolved oxygen(DO), volume loading (Nv) and the intermittent aeration on phosphorus removal of the CIBFR were investigated...
The conversion rule of the 3-ketosteroid-Delta1-dehydrogenation by Arthrobacter globiformis ATCC 31250 and the effect of the cell wall and cell membrane on biotransformation have been studied. Steroid compounds with different functional groups show a diversity of physicochemical properties at the macroscopic level. We measured the melting point, specific rotation and absorption coefficient of 3-ketosteroid...
