【第 1 段建议】: 1. "lmpact"应为"Impact"（字母"l"应为"I"）。 2. "High Weir Spiral Classifier"应为"High Weir Spiral Classifier"（重复空格）。 3. "Submerged Spiral Classifier"应为"Submerged Spiral Classifier"（重复空格）。 4. "EPCO"建议根据上下文确认是否为"EP"或其他缩写，以确保准确。 5. "Mobile Demand"在中文文中可能应为"移动需求"，需确认是否为特定名词。 6. 在"Cases"及"Services"之后的文本中应统一用"；"结尾。 请根据必要情况进行调整。 --- 【第 2 段建议】: 1. "Hebei Construction Waste Disposal and recycling equipment exhibition 2019" - "recycling" should be capitalized. 2. "2019 , It i" - There is an unnecessary space before the comma, and "i" should be changed to "is." 3. "Exhibition Period: Oct. 28-30,2019" - There should be a space after the comma: "28-30, 2019." 4. "Demand(multiple):" - There should be a space between "Demand" and "(multiple):". 5. "Materials (brochures, catalogs）" - The closing parenthesis is incorrect; it should be a standard parenthesis: "Materials (brochures, catalogs)." 6. "WhatsApp:+86 13761974616" - There should be a space after "WhatsApp:". 7. "Sales Hotline: 0086-21-58386189" - The format here could be more consistent with other numbers. Consider using "+86" or "0086" uniformly for international dialing. 8. "Copyright © 2026" - It is unlikely that the copyright will be in the future. It should likely be "Copyright © 2023" or "Copyright © 2024" based on the date mentioned (October 2023). 9. "Website Map|Legal Notice|Contact Us" - There should be spaces around the vertical bars for consistency: "Website Map | Legal Notice | Contact Us".
