The line-measuring dimension Dlinc has been developed and selected to describe the curved and branched pattes of multi-branched domains (MBDs) formed by using the "low-bias-field method" in magnetic gaet bubble films.The definition of Dline is given. The domain patte processing and the "double boundary description" of MBDs are introduced. It has been verified that the MBD pattes truly possess the characteristic of fractal structure over a certain range. The meaningful Dline seems to be a better parameter to quantitatively describe the curved and branched structure of MBDs, and can be related to the nucleation of vertical Bloch lines in their walls.

进展 互相“交谈”的汽车即将上路 如果汽车能够互相“交谈”，就可以避免很多交通事故的发生。例如，车辆如果能够获得别的车辆、障碍物或行人的信息，就可以更安全地行驶。要实施这些，还面临很多障碍：它们需要一个法律框架和无线频谱的分配方案，以实现车辆对车辆（V2V）通信。美国交通管理部门宣布，正在努力加快推动V2V系统的实施，并为自动驾驶汽车的上路做准备。 探索 石墨烯打造超级蛛丝 石墨烯是最强
