Unsteady two-film model for mass transfer

The classical two-film model for mass transfer between two fluid phases can only be used to describe the steady state mass transfer mechanism. Both the penetration and the film-penetration model are also valid solely when only one diffusion boundary layer exists at the interface between the phases. With a view to surmounting the limitations of the above models a new model has been developed for the mass transfer between two fluid phases with two diffusion boundary layers at the interface. The new model is based on the two-film concept and the Danckwerts distribution function, and is also able to simulate the unsteady state mass transfer mechanism between two fluid phases with two different boundary layers.     

PARASITIC TOLERANT DIFFERENTIAL SC TRANSCONDUCTANCE USING UNITY GAIN BUFFERS

The unity gain buffer will be good to design high frequency SCF if its resistiveeffects can be eliminated,and therefore the whole parasitic sensitivities will greatly be reduced.On the basis of this concept,a novel parasitic tolerant SC DTE(differential transconductanceelement)is proposed.SC floating inductor and integrator fit for high frequency applications areformed by the DTE.The computer simulation and experiment on a third order elliptic LP filterverify its validity.     

45% efficient silicon photovoltaic cell under monochromatic light

Improvements in the performance of silicon photovoltaic cells for solar applications are adapted for nonsolar photovoltaic applications. Improved monochromatic light efficiencies above 45% are reported including efficiencies close to 40% for relatively long-wavelength (1.064 μm) light as produced by neodymium-doped yttrium-aluminum garnet (Nd:YAG) lasers     

激光对生产β-胡萝卜素的藻种——盐生杜氏藻(Dunaliella salina)诱变的研究

用激光(335nm,0.014MW/mm~2)对产生6-胡萝卜素的盐生杜氏藻(Dunaliella Salina)进行了诱变研究,藻的存活率为90％。诱导后筛选到三个盐生杜氏藻的品系。生长速度较原藻最高增加20％,长度增加7.5％,萨-胡萝卜素生产能力为0.48mg·100ml~(-1)天~-1),比原藻增加19％。
