【第 1 段建议】: 1. "lmpact Crusher" 应为 "Impact Crusher" (小写字母l应为大写字母I) 2. "l" 应为 "I"（"Vertical Shaft lmpact Crusher"应为"Vertical Shaft Impact Crusher"） 3. "How to us" 应为 "How to use" (文本不完整) --- 【第 2 段建议】: 1. "e the gap" 应为 "Is there a gap" 2. "Raymond mills" 应该为 "Raymond mill"（保持一致性） 3. "the production of Raymond Mill" 中的 "Mill" 应小写，改为 "mill" 4. "etc.," 之后应去掉逗号，改为 "etc." 5. "Raymond is not afraid of softness. Hard has long been known, because..." 中的表述不清晰，建议重写为 "Raymond is not afraid of soft materials; it has long been known that hard materials can cause difficulties..." 6. "the same model Raymond The mill" 中的 "Raymond The mill" 应为 "the same model of Raymond mill" 7. "not only because of the cheap price" 可以改为 "not only because of its low price" 8. "the bag is good" 可以改为 "the bag material is good" 请根据上下文适当调整这些建议。 --- 【第 3 段建议】: 1. "to produce and move in the acute production" - "acute production" is unclear and may need revision for clarity. 2. "WhatsApp" - should be consistent in formatting; consider removing repeated "WhatsApp" entries. 3. "Demand(multiple):" - there should be a space before the opening parenthesis: "Demand (multiple):". 4. "Materials (brochures, catalogs）" - the closing parenthesis should be a regular parenthesis: "Materials (brochures, catalogs)". 5. "EPCO Service" - if "EPCO" is intended, consider adding clarity if it should refer to "EPC" or another term. 6. "Copyright © 2026" - ensure the year is accurate, as the current date is October 2023. Please review these points for correctness and clarity. --- 【第 4 段建议】: 发现的问题： 1. "ocument" 应为 "document" 2. "for PPC参数传递" 中的“参数”应为“参数传递”或“参数”按需求调整具体表述 3. "for(var i=0;i-1)" 语法错误，应为 "for(var i=0; i<tags.length; i++)"
