附件：toosodium sulphate溶液與固體toosodium sulphate的各term情況對比：
toosodium sulphate溶液的優點是濃度準確、use便捷，適合自動化生產，缺點是不適合長途運輸。以下優缺點為對照：
termorder | toosodium sulphate固體 | toosodium sulphate溶液 |
content | 9eight.5-99.5% | three hundred±5g/L |
Store | Hazardous chemicals warehouse | Special storage tank |
Administration | 倉庫Administration人員發貨，工人搬運到配料容器邊。 | 專用管道，倉庫Administration按規定記錄液位。 |
use | 不能直接use，需要在專用配料容器溶解，調整，化驗后抽到use槽子里，再稀釋到所需濃度。 | 直接抽到use的槽子里，再稀釋到所需濃度（如果是three hundredg/L則無需稀釋）。 |
Security | Poor (dangerous chemicals, average risk) | Good (hazardous chemicals, low risk) |
Transportation source | General dangerous chemicals vehicle | Special tank car |
Purchase cost | low | high |
Administration、use成本 | high | low |
Comprehensive cost | Quite | Quite |
conclusion | 適合少量，手工操作的場合use。 | 適合use量大，自動化要求high的場合use。 |
