trunk code的意思|示意

At that point we can (and should) publish to the trunk, i.e. take all new code on the work branch and copy over to the trunk.

此时我们可以(而且应该)将此分支公开发布到主干上，比如将工作分支上所有的新代码复制到主干上。

Each team has their own work branch, since they each need somewhere to test their code before publishing to the trunk.

由于每个团队都要在发布代码到主干前进行测试，因此他们有各自的工作分支。

Developers integrate their code into the trunk as often as possible — typically every few hours — while making sure that all the unit tests pass.

开发人员应当尽可能频繁地把他们的代码集成进主干——典型的是几小时一次，同时还要确保所有单元测试都能通过。
