Can be produced to anti-static, safe and super density material, suitable for precise electronic equipment. 可制成抗静材料,安全超高密度(SD)等成品,适合精密电子使用。
Pulsar is a kind of neutron star with super strong electro-magnetic field and super density. It spins rapidly and extremely stably. Its long-term stability could even be better than the best atomic clock in the world. 脉冲星是一种具有超强电磁场、超高密度(SD)的高速旋转的中子星,其自转周期极其稳定,长期稳定度甚至优于目前世界上最好的原子钟。
A new process ( NCI-8888 ) of replacement Sn plating can be applied for super thin flexible PCB with super density. Sn plating obtained by the process was lead-free, dense, non-whisker, and could stand long time bake at high temperature and reflow for many times. 新型NCI8888置换镀锡工艺获得的锡镀层致密、无铅、无锡须,能承受长时间高温烘烤和多次回流,可用于超高密度(SD)超薄型挠性印制板。
The experiment proved that proceeding two-photon three-dimensional optical data storage with DVD pickup head was feasible, which indicated that two-photon photobleaching technology combined with the current CD / DVD and provided a base for realization of high density and super high density optical data storage. 实验证明了用DVD光头进行双光子三维光数据存储的可行性,表明双光子吸收光致漂白技术可以与现有CD/DVD兼容,为实现多层高密度和超高密度(SD)光信息存储打下基础。
