One technique I remember was using the location of an object to date it, like how deep it was buried.

我记得有一种方法是利用物体的位置来确定它的年代，比如它被埋得有多深。

youdao

These elements are buried four deep in the response (hence the line that sets the returnElement object).

这些元素位于响应的第 4 层深度位置（即设置 returnElement 对象的那一行）。

youdao

When properly done, the database access is buried behind a business logic object so that Web site developers who use JSPs don't know how the underlying database is organized.

在正确完成处理之后，数据库访问被隐藏到了业务逻辑对象之后，因此，那些使用JSP的Web站点的开发人员并不知道如何组织数据库。
