对于需要延迟执行的函数，目前有了两个选择。

For lazily evaluated functions, there are now two options.

youdao

这么做的主要原因在于，从 XML 树检索的大多数集合都是用延迟执行生成的。

The main reason for doing this is that most of the collections you retrieve from an XML tree are yielded using deferred execution.

其次，通过流程标准化、流程延迟执行及流程重组再造可以实现大规模定制生产流程的优化。

Secondly, the thesis optimizes the process by standardizing, delaying and reengineering to make it more adapted to MC.
