在一定程度上降低了信息物理系统中节点的能量消耗，减少了多跳传输中的延时。
On some degree, it reduces energy consumption in Cyber-physical systems, and lessens time lapse in multi-hop transmission.
在信息物理系统中如何能够减少不必要的能量消耗，保证较小的传输延时，提高网络的整体性能，是目前所面临的首要挑战。
The primary challenge at present is how to cut down unnecessary energy consumption, guarantee less time lapse in transmission, and improve the overall performance of the network.
按照相同的方式，您都可以使用单独的拓扑表，来将物理系统的具体硬件信息对于程序隐藏起来。
In the same way, you can use separate topology diagrams to hide the details of the physical system from the application.
对于应用来说，虚拟机系统看起来就像物理系统一样，运行虚拟机系统的物理系统的具体硬件信息对于应用程序来说被隐藏起来了。
The virtual system appears just like a physical system to the application, and the details of the physical system that hosts the virtual system are hidden from the application.
这是在真实物理系统里面很明显的一个简化，但是它抓住了足够的物理特征，给人们提供了很有用的信息。
This is obviously a major simplification of the real physical system, but the hope is that it captures enough of the physics to provide useful insight.
但脆弱的迭加性使得量子信息过程很难在实际的物理系统中得到实现。
However, quantum superposition is quite fragile so that quantum information processes are hard to be implemented in the practical systems.
