三氟碘甲烷,化學式為CF3I,被用作撲滅飛機和飛行中電子設備火災。
化學性質
在陽光下,或在溫度高於100°C時,三氟碘甲烷分解成有害產品氟化氫(HF),碘化氫(HI)和羰基氟(COF2)。
它含有碳,氟,碘原子。實驗表明,雖然三氟碘甲烷對臭氧消耗的潛能小於千分之一,其大氣中的壽命,不足1個月,只剩1%,但是三氟碘甲烷分解後仍會產生氯及氟離子,產生其他溫室氣體。因此,即使分解後,三氟很可能是一個非常有效的溫室氣體。[1]

This is an entry in the Fortnightly Topic Challenge #41: Short and Sweet. 1 letter only could be mean anything . With an additional letter in front , could be used as medicine component and something you definitely learn or at least heard once. Add another letter in front , you would possibly hear that many times . Add an additional letter in front , you would found an independent country . With an additional letter, in the end , you would found something related to apple . Add another letter in the end , you would found something bad . Hint: Each letter is unique .

I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers?
