logarithmic phase

In this paper, a simple method of plotting logarithmic phase frequency response curve for open-loop systems is advanced.

The cell number development of Viola diffusa Ging during a culture course was similar to a "S" curve with apparent logarithmic phase.

The special growth rate of Taxus cell subcultured on logarithmic phase was 1.6 folds of that on stationary phase and the production of taxol was increased by nearly 4 times;
