(Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Note: For questions of the type \"one question per day,\" if a person replies continuously for a month, that is, posts more than 30 times, their score will be assigned as 2 points, which is the lowest possible score. Click once to reply; if multiple replies are made, points will be awarded as appropriate, as deleting posts is also a waste of time. B Rating Criteria: 2 Wealth points for incorrect responses; *incomplete* answers result in 3–8 points. 10 Wealth points are awarded for correct answers, provided there is a detailed explanation; if additional *answers* are missing, 15–20 Wealth points are given. Please use these criteria for scoring. Note: If there are editing records after answering, only those who participated will be given points. For continuous malicious spamming, 2 points will be deducted each time, with no upper limit. Pure numbers, pure emojis, or random letters that have nothing to do with the answer are all considered malicious spamming. Points will start to be deducted after three warnings. 2017 Q&A Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) http://bbs.hcbbs.com/thread-1597792-1-1.html
