Treat global concerns globally: Program elements should not have much say in the participation of concerns such as tracing and profiling in a crosscutting implementation.

要全局地对待全局关注点：程序元素不应当对关注点(比如在横切实现中进行跟踪和分析)的参与起什么作用。

Because this tracing work is interleaved with program execution, the GC can lose track of certain objects that the application can "hide" through executing loads and stores.

由于这种跟踪工作与程序的执行是交叉进行的，应用程序通过执行加载或存储将某些对象“隐藏”，因此GC可能会丢失这些对象的跟踪。

In this program, NVIDIA showed us ray-tracing, a computationally intensive 3D imaging feature, which only became available in After Effects with the release of CS6.
