Based on first‐principles calculation, we found a new type of three‐dimensional (3D) topological semimetal: β‐PbO2. When spin–orbit coupling (SOC) is ignored, β‐PbO2 behaves as a node‐line semimetal, but in the presence of SOC, the system turns into 3D Dirac semimetal, and the Dirac points are protected by C4 crystal symmetry. Moreover, the surface states and Fermi arcs on the semi‐infinite edge...
This article introduces the background of the design and a unique idea of PCI interface circuit at first. The circuit mainly focuses on the Linux-based driver by introducing interrupt. Then the paper describes the compilation and installation of driver and interruptions which include requesting, handling, and releasing. At the same time, the application of PCI interrupt in data acquisition card is...
