Aim:
To know the growth curve in the dog’s blood
Steps:
1.Do experiment to measure the number of bacteria;
2.Establish the gray logistic model to simulate the growth of bacteria;
3.Determine the parameter through the experiment;
4.Test the predicted results.
Results:
The gray logistic model gets the good forecasting result.And the model precision is excellent.
Background:
The color of blood is so deep that it is not fit to measure the OD value to determine the growth of bacteria in the blood.Then we choose dilution-plate method to detect the number of total bacteria. So we coated a large number of plates.The logistic model of population can well predict the increase of population.
Establish the logistic model:
In the environment of the blood,the number of bacteria have a maximum value K.And when the number of bacteria approach K,the growth rate is next to nil.Then the population growth equation is as follows:
The solution of the equation is :
