以下是源代码中文案中的拼写错误、单复数误用及标点错误的列表： 1. "too much noises" -> 应为 "too much noise"（"noise" 为不可数名词，不能加复数形式）。 2. "has been running smoothly. It only needs to work eight hours per day" -> 更加自然的表达应该是 "has been running smoothly; it only needs to work eight hours per day"（句子之间应使用分号）。 3. "grinder roll and ring have little wear" -> "grinder rolls and rings have little wear"（应使用复数形式以匹配上下文）。 4. "The spare part was sent directly from the factory in Jiangsu" -> "The spare parts were sent directly from the factory in Jiangsu"（上下文暗示这是一个复数的情况）。 5. "the erection and commissioning of all the equipment were completed in only half a month" -> "the erection and commissioning of all the equipment were completed in only half a month."（句末缺少句号）。 6. "which released my worries a lot" -> "which greatly alleviated my worries"（更自然的表达方式）。 7. "at the time of purchasing the equipment" -> "at the time of purchasing the equipment,"（句末缺少逗号，导致阅读流畅性下降）。 8. "the yield has increased substantially" -> "the yield has increased substantially."（句末缺少句号）。 这是根据上下文理解而提出的建议，具体修正可以根据你的需求调整。
