自动化检测设备及系统可靠性的提高越来越依赖于设备及系统的整体设计方案。模块式结构是一种容错系统,小型化模块使得储备冗余技术得以实现,大大提高了系统寿命。文中并从该
Tantalum nitride (TaN) thin films are achieved on Si(111) and SS317L substrates by cathodic vacuum arc technique, which is rarely reported in the literature. Th

We show that the scattering between two solitary waves in the Fermi-Pasta-Ulam model with interaction potential V(x) = αx2/2 + x4/4 can be classified into four
