In this paper, a simple method of plotting logarithmicphase frequency response curve for open-loop systems is advanced.
文章给出了绘制开环系统对数相频特性曲线的简便方法。

The cell number development of Viola diffusa Ging during a culture course was similar to a "S" curve with apparent logarithmicphase.
细胞悬浮培养一个周期过程中细胞数目增长的动态基本上是一条S型曲线 ，对数生长期明显 ；

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