“focusing on attributes and reflection”是什么意思？

Part III gets to the heart of the .NET Framework, focusing on attributes and reflection, remoting, threads and synchronization, and streams. Part III also illustrates how to intemperate with COM objects.你说的是这一句吗?翻译:
第三部分将介绍有关.net framework的核心部分.重点是属性,放射,远程对象访问,线程,同步,流对象.还将用图例介绍有观如何使用COM对象的情况.
