摘要
通过建立一个关于单位面积钉螺变化率的数学模型,并对模型中的一些参数分两种不同的情况进行求解.再利用数学软件Mathematic对模型的各种解赋予实际的参考数据进行数值模拟,并对控制措施下的钉螺死亡率k的不同取值,得到相应的模拟图形,根据图形来探讨在不同的控制措施下钉螺数量的变化情况.
In this paper,we establish a mathematical model about the variable rate of the snail on the unit area,and model some of the parameters of two different points to solve the situation.Mathematic mathematical software reuse a variety of solutions of the model reference given to the actual numerical simulation,and control measures through snail mortality under the different values,the corresponding analog graphics,according to graph the effects of different control measures under the changes in the number of snails.
