Please rewrite the entire text to completely eliminate AI writing traces, strictly adhering to all the following modification requirements:
1. Sentence structure and punctuation standards:
Delete all AI-specific concatenated sentence patterns such as "……+…+…", abandon the excessive use of parenthetical explanations in brackets, and instead use natural, fluent written expressions with varied sentence lengths;
Significantly reduce unnecessary double quotation marks. Only mark professional terms at their first occurrence, remove quotation marks from ordinary nouns, and eliminate the AI habit of quoting words throughout the text;
2. Subheading optimization:
For existing subheadings, keep only the core content before the colon, directly delete the redundant modifiers after the colon, simplify the titles, and align with conventional student thesis writing;
3. Data processing core requirements:
Substantially reduce percentages and quantitative estimates in the text that lack sources or basis. Delete all data that is not from actual measurements or literature citations;
If data is retained in the text, it must be accompanied by a marked source; replace statistics without reliable sources and vague proportional descriptions with qualitative textual expressions to avoid being questioned about data basis during defense;
4. Writing style and human touch adjustment:
Weaken the machine-standardized, template-like written tone, adjust to a plain and natural tone as if written by the student themselves, with more flexible sentence splitting, reduce overly regular parallel structures, and use colloquial academic transitions between paragraphs to reduce mechanical feel;
Bottom-line requirements:
After modification, ensure that the original core viewpoints, experimental logic, and professional content remain completely unchanged. Only adjust the form of expression, do not cut key research information. Output the full text after rewriting.
