Performance art is a form of performance in which the actions of an individual or a group at a particular place and in a particular time make up the work.

中文翻译：表演艺术是一种表演形式，在这种表演形式中，个人或者团体在特定的地点和特定时间的行为构成/组成了这种工作任务.

It differs from traditional forms of performance such as theatre, in that often there may be no written script and no pre-set theatrical set or stage directions.

中文翻译：它不同于传统的表演形式，例如戏剧工作/舞台表演，因为可能没有书面剧本也没有预先准备剧场的设置和舞台说明.
