【第 1 段建议】: 1. "lmpact" should be corrected to "Impact" (the lowercase 'l' should be an uppercase 'I'). 2. "Dewatering Machine" should be in the same format as the other headings for consistency: it should be listed under the bulleted points. 3. "EPCO" should be clarified or formatted consistently if it stands for something specific (if it is an acronym, it needs to be defined). 4. "other" should likely be capitalized for consistency with the "Product" heading: it should be "Other." Please check for further context to ensure proper formatting as it can affect meaning. --- 【第 2 段建议】: 1. "ggregates" 应为 "Aggregates" 2.

"and reminded the customer to spare emergency electrical components" - consider changing "spare" to "spare for" for clarity. 4. "CIP vs. CIL: Key Differences in Gold Cyanidation Processes" - the title should preferably use "in" instead of "in" for consistency (e.g., "CIP vs CIL: Key Differences in Gold Cyanidation Processes"). 5. "Get Solution & Quotation" - for consistency in verb forms, consider changing "Get" to "Get a" (i.e. "Get a Solution & Quotation"). 6.
