We should change the definition of solution.
我们应该更改解决方案的定义。
The oil production depending on time is not a one graph, but a set of graphs, showing the uncertainty of this solution. All the graphs in this band are solutions.
取决于时间的采油量不是一个图表，而是一组图表，显示了该解决方案的不确定性。该区间内的所有图形均为解决方案。
Sensitivity analysis
敏感性分析
We should check the solution sensitivity to changes in calculation parameters. In other words, we should check
我们应该检查解决方案对计算参数变化的敏感性。换句话说，我们应该检查
Sensitivity to time step size limit,
对时间步长大小限制的敏感性，
Sensitivity to accuracy of linear and non-linear problem increase,
线性和非线性问题增长的精度的敏感性，
Sensitivity to number of cores.
对内核数量的敏感性。
We should check the solution sensitivity to changes in model parameters. There are many of them. Check at least those that may be automated easily:
我们应该检查解决方案对模型参数变化的敏感性。（参数）有很多。至少检查那些可以轻松实现自动化的功能：
