The properties of the new optical fibre made of BP-81-16 cladding glass and F626/356 core glass are satisfactory.

其中BP-81-16包层玻璃已投入生产，它与F626/356芯玻璃组合拉制的光导纤维性能良好。

The total internal reflection phenomenon, as well as the high purity of the core glass, enables light to travel long distances with little loss of intensity.

全内反射现象与核心玻璃的高纯度一样，使光线几乎无强度损耗传递长距离成为可能。

One of the earliest methods developed for making glass containers is called core-forming.

The Edge sports a dual-core 1Ghz CPU, tempered glass (instead of acrylic), 5-megapixel camera, 4-inch 233-ppi display and Android Jelly Bean.

ENGADGET

Embedding the structural support in the core made it possible to cantilever the roof and thus wrap a glass facade around the building, using vast expanses of insulated, triple-pane glass and mahogany mullions.

One example the company has developed is a crystal fibre that squeezes light into such a narrow core that the intensity of the light modifies the optical properties of the glass itself.
