Okay, the user wants me to translate "borate salts" into Simplified Chinese. Let me check what "borate salts" refers to. Borate salts are compounds containing borate ions, which are derived from boric acid. The common term in Chinese for borate salts is "硼酸盐".
Wait, the user provided the translation rules. Rule 1 says to translate all content into Simplified Chinese. Rule 2 says if it's already in Simplified Chinese, leave it as is. Rule 3 is to provide only the translation without explanations.
So, the input "borate salts" is in English. The correct translation should be "硼酸盐". I need to make sure there's no other possible translation. Let me confirm. Yes, "硼酸盐" is the standard term used in chemistry for borate salts. No need to add anything else. The user wants just the translation, so I'll output "硼酸盐" without any extra text.
