No.4  (Original) Unknown variables or time significantly (influence, influences) the product quality when the machine parts are in close proximity to each other.  (Revised) Unknown variables or time significantly influences the product quality when the machine parts are in close proximity to each other.

6. [Note 2.12]  Avoid wordiness by saying near instead of in close proximity to.

10. [Note 2.13]  Depending on the sentence’s context, significantly, markedly, and substantially can be used as alternatives to much and greatly when the Chinese meaning is 很多.

16. [Note 2.15]  Avoid wordiness by saying always instead of in all cases.

17. No.12  (Original) To test the constructed network model and to identify the real optimal parameter setup (is, are) of primary concern in this study.  (Revised) To test the constructed network model and to identify the real optimal parameter setup are of primary concern in this study.
