幻灯片上的图形展示的是节的数量与悬垂系数的关系。X轴为节的数量，y轴为悬垂系数。这个实验是为了研究直流电流对网格分辨率的依赖性。图上有24种不同的网格，范围为250到130个节点。此外，图形上还有3个刚度值的覆盖系数，分别为低刚度、中等刚度和高刚度。低刚度对应的是桃皮涤纶，中等刚度对应的是仿羊毛，高刚度对应的是柞蚕棉。计算得到的低刚度、中等刚度、高刚度的平均值分别为23.2%、52.4%、77.3%。从图中可以看出，我们的模型对DC的计算非常稳定，因此模型在网格分辨率方面很强。

The graph on the slide shows the relationship between the number of sections and the drape coefficient. X-axis is the number of nodes and y-axis is the suspension coefficient. This experiment is to study the dependence of DC current on grid resolution. There are 24 different grids, ranging from 250 to 130 nodes. In addition, there are three coverage factors of stiffness values on the graph, which are low stiffness, medium stiffness and high stiffness respectively. Low stiffness corresponds to peach skin polyester, medium stiffness corresponds to imitation wool, and high stiffness corresponds to tussah cotton. The average values of low stiffness, medium stiffness and high stiffness are 23.2%, 52.4% and 77.3% respectively. As can be seen from the figure, our model is very stable in DC calculation, so the model has strong grid resolution.
