RBL（RBL）
網路用語無固定，大部分為中文縮寫。泛指不願意明說的暗語：弱爆了,日不落，忍不了,然而並沒有什麼卵用等；常見的含義為Research Based Learning.
RBL是英文Realtime Blackhole List的縮寫，即實時黑名單列表。在該列表中的IP位址對外發布過垃圾郵件。因此，它象病毒定義檔案一樣被垃圾郵件過濾器用於過濾由該列表中發出的垃圾郵件。網上有免費的RBL可以下載。由於該列表被實時更新因此能夠保證被過濾的最新垃圾郵件。
Short for Realtime Blackhole List, a list of IP addresses whose owners refuse to stop the proliferation of spam. The RBL usually lists server IP addresses from ISPs whose customers are responsible for the spam and from ISPs whose servers are hijacked for spam relay.
As subscribers to the RBL, ISPs and companies will know from which IP addresses to block traffic. Most traffic blocking occurs during the SMTP connection phase. The receiving end will check the RBL for the connecting IP address. If the IP address matches one on the list, then the connection gets dropped before accepting any traffic from the spammer. Some ISPs, though, will choose to blackhole (or ignore) IP packets at their routers. The goal here is to block all IP traffic.
It is important to note that all e-mail and packet blocking is done by the recipient, not the RBL administrator, which is only responsible for bouncing spam that is directed at its servers.
The RBL was created by Mail Abuse Prevention System (MAPS) LLC., but there are other entities that keep RBLs aside from MAPS.
以探究為基礎
RBL，Research Based Learning，“以探究為基礎”的教學，是一種以探究未知問題為基礎，設計性綜合性實驗為載體，構建開放式、學生主動參與的教學模式。它不同於傳統教學，旨在通過充分調動學生的學習主動性、積極性和創造性來提高學生髮現問題、分析問題和解決問題的能力，提高學生自學能力和實踐能力，培養學生的科學思維、創新意識。
