btn怎么记

This article mainly concentrated on the ferroelectric, piezoelectric and upconversion luminescence properties of the rare-earth-ion Tb3+ and Yb3+ co-doped BTN ceramics. First, upconversion emissions were studied in order to expand the optical properties of ferroelectric ceramics.

首先研究其上转换发光性质，以期拓展铁电陶瓷材料的光学特性。

The edge weight straight-line distance between every two stations will be got by computing the vertex weight. Further we model the BTN to a weighted complex network.

在此基础上，引入了网络点权，即站点的经纬度，进而得到网络的边权，即站点间的直线距离，把公交网络进一步建模成一个加权的复杂网络模型。

In this review article, the advances in control and synchronization methods of beam halo-chaos in the beam transport networks ( BTN) is reviewed and summarized.

总结了一类规则网络&传统的规则束流输运网络中束晕-混沌的控制与同步方法的研究进展。
