How to make a quantitative measure for the progress of science and technology? Now, there are many model for this problem, Cobb Douglas production function model, the growth rate equation and so on.

如何对科技进步进行定量测度？目前测量科技进步的模型很多，如柯布-道格拉斯生产函数模型、增长速度方程等。

To explain the relationship of temperature and growth rate of each stage, the exponential sine equation has been derived.

通过正弦指数模型描述黄瓜在各个生长阶段发育速率与温度的关系。

The secondary model was based on the classical Square Root equation, which displayed a good linear relationship between the growth rate of Aspergillus versicolor and temperature.

二级模型采用经典的平方根模型拟合，发现杂色曲霉生长速率与温度呈较好的线性关系。

Some will be growing very rapidly, some will be growing less rapidly, and what this equation shows you here or that rate of growth the to the doubling time of cells.

有些会生长得更快些,有的慢一些,而这个方程告诉你,即生长的速率和细胞倍增的时间联系起来
