[0058] see figure 1 , is a schematic flowchart of an embodiment of the method for predicting the tensile strength of a paper sheet provided by the present invention. like figure 1 , the construction method includes step 101 to step 105, each step is as follows:
[0059] Step 101: Obtain N sets of paper production process data; wherein, N is a positive integer greater than 1, and each set of paper production process data includes the first fiber shape data before refining, the refining process data, and the first fiber shape data after refining. Two fiber morphology data, paper machine process data and sheet tensile strength.
[0060] In this embodiment, step 101 is specifically: acquiring the first data of N sets of paper sheet production process; wherein, N is a positive integer greater than 1; preprocessing the first data, removing dirty data or data that cannot be directly analyzed , to obtain N sets of second data; normalize the second data to obtain N sets of third dat...
