Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

This manuscript is well-written and provides informative content. I recommend its publication subject to minor revisions.

Regarding the literature review, the cited references are predominantly from publications prior to 2018. I strongly recommend that the authors incorporate more recent works from the past five years to ensure the review reflects the current state of research.

Additionally, what are the academic contributions of the study? I suggest that the authors explicitly highlight the key academic contributions either in the Introduction section or in the Conclusions to clarify the novelty and significance of the work. This is very important for a academic paper.

Reviewer 2 Report

Comments and Suggestions for Authors

1. While reading the title, I noticed that the word "From" is not appropriate to write in uppercase. Additionally, the number "2" should be replaced by the word "two", to maintain consistency and formality
2. In the abstract, the authors designate "Town Gas" as the official study site; nevertheless, inconsistent use of the site's name within the paragraph detracts from the overall clarity of the manuscript
3. The introduction lacks research questions and hypotheses. Moreover, the study's objectives are not articulated
4. It appears that the manuscript lacks adequate English writing, negatively impacting the clarity and coherence of the scientific text. For instance, the phrase "Accordingly, the leakage percentage of each component can be estimated accordingly" illustrates redundancy
5. The Results and Discussion sections require significant improvement, particularly regarding the comparison and in-depth analysis of the main evidence, which appears to be related to the absence of well-defined research questions and hypotheses
6. The references within the manuscript do not conform to the formatting guidelines specified by the authors' instructions, which require that "reference numbers be placed in square brackets [ ]."
