首先先来了解一下interlocutory的意思：

interlocutory指中间的；临时的；暂时的；非最后的；在诉讼程序进行中的。

具体而言，通常指在诉讼过程中对与案件有关的某些事项或法律点作出的决定，而非对整个案件作出最终的处理。

例如：

interlocutory application中间申请

在案件审理过程中提出的寻求获得暂时的救济，而非为获得终局判决的申请。也指为了使案件能得到正确的审理并最终被裁决而在诉讼进行中向法庭请求作出命令的申请。

因此：

interlocutory injunction指临时/中间禁令。

指在法院对相关事实作出最终判定之前为维持当事人之间的现状而发布的禁制令。在美国，通常认为中间禁制令包括两类，一是预备性禁制令〔preliminary injunction〕，法院应在给予被告人通知及参加就是否应签发该禁制令而举行的听审的机会之后，才能签发；二是临时禁止令〔temporary restraining orders〕，它是在如果不及时提供救济将会造成不可弥补的损害，而时间又不允许送达通知和举行听审的情况下由法院签发。所以它与前者的区别在于它是由法院为一方当事人的利益而签发的，没有给予对方事先通知及参加听审的机会。但也有许多司法区不将临时禁止令作为禁制令的一种。

Also known as an interim injunction, an injunction made before a case goes to trial. It can be expressed to remain in force for a particular period of time. Otherwise, it remains in force until the matter comes to trial or until the court makes any further order. When the matter comes to trial, the court will decide whether or not to make a final injunction.

interlocutory hearing指临时听审。

不是为了作出最终裁决，而是为了使案情得以以某种形式陈述出来，从而使其得到恰当的审理并根据是非曲直对其作出终局判决而进行的听审。Interlocutory Hearing - any hearing at which a pretrial or court ruling is requested. Application in Divorce Interlocutory hearings are provisional and result in pretrial orders.

以下为相关双语示例，供参考：

Before and during this period, there could also be interlocutory hearings for considering issues such as applications for substituted service or dispensation of service, appointment of a person to represent the estate of a deceased respondent as well as extension of time to file and/or serve relevant documents.

在此之前及在此期间，审裁处或会进行临时听审，以考虑替代送达申请、免除送达申请、委任某人代表已去世答辩人的遗产、延期存档及／或送达有关文件等有关事宜。

Clause 9 amends section 21L(3) of the High Court Ordinance (Cap. 4) so that the power of the Court of First Instance to grant an interlocutory injunction under the new section 21M is also exercisable irrespective of whether the party against whom the injunction is made is domiciled, resident or present in Hong Kong.

草案第9条修订《高等法院条例》(第4章)第21L(3)条，以致不论临时禁令所针对的一方是否居于或身在香港，或其居籍或本籍是否在香港，原讼法庭均可根据新的第21M条行使批予临时禁令的权力。
