Popular subtitles are srt, smi and ssa. Because it is a text format, it is relatively small, generally not more than 100 K, among which srt text subtitles are the most popular, because its production specification is simple, one code at a time+one subtitle, and it is quite simple to make and modify.

With style files, srt can also bring some special effects to fonts.

SRT can also refer to the research and training of college students:

In foreign countries, there is a graduate research opportunity program implemented by MIT, which gives undergraduates an "opportunity" to participate in scientific research and training. 70% of MIT undergraduates have participated in this activity during their four years in college.

At home, Tsinghua University first learned from the UROP plan and started to create and implement the SRT plan from 1996. Many domestic universities have launched SRT projects. The form of SRT plan is to carry out extracurricular scientific research activities with students as the main body under the guidance of teachers. Participants are mainly undergraduates.

SRT plans to implement two-way selection of tutors and classmates, and students can choose projects according to their own conditions. Compared with classroom teaching, SRT project involves a wider range of knowledge fields.

In this process, we can give full play to students' independent working ability and initiative, and cultivate students' critical spirit of independent thinking and dare to doubt. Students can be "self-centered" and cultivate their independent ability in investigation and research, literature review, analysis and demonstration, scheme formulation, design or experiment, analysis and summary, etc., and the tutor plays a leading role.

Students who complete the SRT program can get corresponding credits and grades, and students who reach a certain level can also replace their related curriculum designs and even graduation designs.
