The functional relation among the growth period t, the initial concentration of Chlorella ellipsoidea and the initial amounts of nitrogen, phosphorus, potassium, and magnesium for the tube growth in 20ml Chlorella medium in 100ml test tube at 26℃ under 5000 lux is dt = (∂t/∂n)dn + (∂t/∂p)dp + (∂t/∂k)dk + (∂t/∂m)dmg +(∂t/∂c)dc = 2.5dn - 1.04dp - 0.1dk- 0.2dmg - (30/c)dc . Integration of this equation gives t = -2.5n - 1.04p - 0.1k - 0.2mg - 30log_eC +u = -2.5n - 1.04p - 0.1k - 0.2mg - 69log_10C +u (u: integration constant) . In this experiment, p=50, n=35, k=165, mg=40, and C=0.9 give t=132, therefore u=248.7 and the above equation becomes t = -2.5n - 1.04p - 0.1k - 0.2mg - 69log_10C +248.7 |
