【第 1 段建议】: 1. "lmpact"应为"Impact"（字母"l"应为"I"）。 2. "Semi-mobile"应为"Semi-Mobile"（首字母需大写以保持一致性）。 3. 在"High Weir Spiral Classifier"和"Submerged Spiral Classifier"之间的空格应减少到一个。 4. "Crushing & Screen"中的"Screen"应改为"Screening"以确保正确性和一致性。 --- 【第 2 段建议】: 1. "pment" appears to be a typographical error and should be removed or corrected. 2. "a very large portable crusher plant in Asia" is used excessively and can be rephrased for better readability. 3. "with reliable quality and high efficiency" could be rephrased for clarity; consider adding a comma after "quality". 4. "when they choose" at the end of the text seems to be incomplete; consider rephrasing or completing the sentence. --- 【第 3 段建议】: 1. "WhatsApp" should be consistently capitalized and should not be repeated. 2. "WhatsApp:" should have a space after the colon. 3. "Materials (brochures, catalogs）" should use a closing parenthesis instead of a closing parenthesis. 4. " Copyright © 2026" should have a space between "Copyright" and "©". 5. "EPCO Service" should be consistent with other entries in its casing (should probably be "EPCO service"). 6. "Youtube" should be spelled "YouTube" for correct branding. 7. "Tiktok" should be spelled "TikTok" for correct branding. 8. "and after-sales service" should not have an additional space before "and". Other points noticed include formatting inconsistencies and lack of spacing in certain areas (like between items in lists), but the specific errors listed above are the crucial ones.
