【第 1 段建议】: 1. "lmpact" 应为 "Impact"（字母 "l" 应为 "I"）。 2. "Vibrat" 应为 "Vibration"（应为 "Vibration" 的完整单词）。 其他无错误。 --- 【第 2 段建议】: 1. "the other three factors affect the bearing vibration in vibrating screen." - 应改为 "the other three factors affecting the bearing vibration in the vibrating screen." 2. "Too small radial internal clearance cause high-frequency vibration" - 应改为 "Too small radial internal clearance causes high-frequency vibration" 3. "too large radial internal clearance cause low-frequency vibration." - 应改为 "too large radial internal clearance causes low-frequency vibration." 4. "the elastic system of bearings." - 应改为 "the elastic system of the bearings." 5. "the retainer will cause have large radial runout" - 应改为 "the retainer will have large radial runout." 6. "the increasing of radial internal clearance" - 应改为 "the increase in radial internal clearance." 7. "leading to the vibration more serious." - 应改为 "leading to more serious vibration." 8. "the strong excited force will cause the elastic vibration of bearings." - 应改为 "the strong excited force will cause the elastic vibration of the bearings." 9. "making the temperature rise of bearings very high." - 应改为 "making the temperature rise of the bearings very high." 10. "the radial internal clearance decreases sharply, accelerating the friction and making the temperature rise increase further." - 应改为 "the radial internal clearance decreases sharply, accelerating the friction and further increasing the temperature rise." --- 【第 3 段建议】: 1. "strongly high-frequency vibration" 应改为 "strongly high-frequency vibrations" (复数形式)。 2. "Materials (brochures, catalogs）" 中的右括号应为英文格式，改为 "Materials (brochures, catalogs)"。 3. "Demand(multiple):" 中的空格缺失，应改为 "Demand (multiple):"。 4. "WhatsApp:+86 13761974616" 中"WhatsApp:"和电话号之间缺少空格，应改为 "WhatsApp: +86 13761974616"。 5. "Sales Hotline: 0086-21-58386189" 和 "0086-21-58386176" 行之间没有标点符号，建议将其合并为 "Sales Hotline: 0086-21-58386189, 0086-21-58386176" 提高可读性。
