螺旋藻培养液光衰减规律的研究

Study on the Light Affenuation Model of Spirulina Platensis Culture

通过对影响光衰减因素的研究，本文建立了一个能较好地描述螺旋藻培养液中光照强度（I）、螺旋藻浓度（OD）及培养液深度（h）之间关系的数学模型：I =I_0 exp [(0.1658 * OD－0.0699) * h^2 + (-0.833* OD－0.0998 ) * h + (-0.1468 * OD^2+0.6117*OD－0.4036)。经检验该模型的总体误差仅为5.7%，并且能比较客观地反映螺旋藻培养中的光衰减现象。

A light affenuation mathematical model of Sprulina platensis is established. The result shows that the relations bewteen light density ( I ), culture liquid concentration ( OD) and culture liquid depth ( h ) of the Spirulina platensis could be described in the mathematical model of I = I_0 exp [ ( 0.1658* OD－0.0699 )* h^2 + (-0.833* OD－0.0998)* h + ( -0.1468* OD^2 + 0.6117* OD－0.4036 ).
