VBA Code for Copying and Modifying Data Between Excel Sheets

This code is a nested loop that iterates through rows in two different sheets and copies values from one sheet to another.

The outer loop iterates through rows in the '过程数据' sheet, with the loop variable k starting at an unknown value (not shown in this code snippet) and presumably incrementing by 1 each time.

The inner loop iterates through rows in the '参考数据' sheet, with the loop variable j starting at 1 and incrementing by 1 each time until it reaches 949.

Within the inner loop, the code copies values from cells in columns G, I, J, and K of the '参考数据' sheet and pastes them into cells in columns A, B, C, D, and E of the '过程数据' sheet.

Specifically, the code pastes the value from column G into column A, the value of a variable named Xhc into column B, the value from column I plus 0.06 into column C, the product of a variable named ValueC and the value from column J into column D, and the value from column K plus 0.06 into column E.

Overall, this code appears to be part of a larger script that is automating some kind of data processing task.
