高强度的

The error of the elongation is 2.3%, by the multi-dimension linear regression model, the relative error are from ? 5% to ? 15% respectively. Comparing the results, it can be found that the neural network overmatches the multi-dimension linear regression. So that, the model can be used in the production of the marine propeller aluminum bronze.
