听说，国外一些高校经常会办brown bag session（午餐研讨会），大家一边吃着午饭，一边听教授们说说最新的研究项目进展、新兴课题什么的，吃饱肚子的同时，脑袋也充实了不少。

A brown bag seminar or session is generally a training or information session during a lunch break. Brown bag is a symbol for meals brought along by the attendees, or provided by the host. In the USA, those are often packed in brown paper bags. Brown bag seminars normally run an hour or two.
午餐研讨会（brown bag seminar/session）就是在午餐时间进行的培训或信息共享会。Brown bag（棕色袋子）代表参与者自带或者主办方提供的午餐。因为在美国，午餐盒饭多半都装在棕色纸袋里。午餐研讨会通常都持续一到两个小时。
The aim is to use regular breaks, e.g. the lunch break, to provide some information to the attendees in a voluntary and informal setting. It is often followed by a discussion of the topic. They are an interesting medium for knowledge management and internal communications.
午餐研讨会的目的是利用午餐休息时间以自发的、非正式的方式为参与者提供一些信息。信息分享之后一般都会就某个话题进行讨论。这是知识管理和内部交流的一种有趣媒介。
In universities, especially for graduate students, brown bag seminars are often offered to update the researching community about ongoing research. Usually held by schools, universities and governmental institutions, they involve lectures, presentations, or talks by researchers, mostly professors about their ongoing research.
高校尤其会针对研究生举行这样的研讨会来让大家了解最新的研究。这些研讨会通常由学院、大学和政府机构主办，采用讲座、演示或研究人员的发言等形式，多数都是一些教授介绍他们正在进行的研究。
