Scientific and rational collocation"后缺少标点符号。 --- 【第 3 段建议】: 1. "checkedwhether" should be corrected to "checked whether". 2. "vulnerableparts" should have a space: "vulnerable parts". 3. "and the roller should be replaced" should be changed to "and the rollers should be replaced" for consistency in pluralization. 4. "including the replacement of vulnerable parts" should be rephrased for clarity, but this is optional based on style. 5. "To be Our Agent" should be rephrased for consistency in capitalization, possibly to "To Be Our Agent". 6. "Demand(multiple):" should have a space: "Demand (multiple):". Note: The term "brochures, catalogs）" has a mismatched parenthesis; it should probably be "brochures, catalogs)". Overall, ensure proper formatting for consistency across points, such as bullet points or number formatting in the "Demand" section.
