So, it is a very concerned question how the optical network base on SDH system evolve to intelligent light network.

因此，基于SDH体制的光网络如何向智能光网络演进是业界非常关注的问题。

In this paper, the mathematical model of multihop light network is established, and it is divided into connectivity problems and routing problems.

研究并建立了多跳光网络的数学模型，把该模型分解成连接问题模型和路由问题模型。

The light network will carry on the evolution in 3 domains: High-capacity light exchange, ultra long-distance solution and based on ASTN netted network overhead construction.

光网络将在3个领域进行演进：高容量的光交换，超长途解决方案和基于ASTN的网状网网络架构。

The polymers return to a pre-defined shape when heated to a certain temperature, and, when damage is detected, an infrared laser sends light through the network to the damaged area, triggers the shape-memory, and commands the area to repair the crack or tear -- regaining up to 96 percent of its original strength.

French Foreign Minister Alain Juppe told a radio network Thursday that "light must be shed" on events leading up to the shootings by Merah.

CNN: France asks: Were warnings missed on Toulouse killer?

Using his unique format that presents science in an exciting way, he has volunteered at schools both locally and in communities where he travels by connecting with underserved schools through the volunteer network of Points of Light.
