; 文章编号:1672-7207(2011)02-0419-08 Synchronous reference frame method for reactive and harmonics currents detection based on sequence component extraction MU Long-hua, L? Jun... current, an improved synchronous reference frame method based on sequence component extraction in the time domain was presented. The results show that for the use of general dq0 theory without PLL......
of direct preparation of lead sulfatepowders from galena concentrates QIN Wen-qing, LIU Hui, SUN Wei (School of Minerals Processing and Bioengineering, Central South University, Changsha 410083, China) Abstract: In traditional process of lead sulfate there exists some disadvantages such as longer flow and higher energy-consumption. In order to explore a new process to produce PbSO4, the methods......
steel frame (CSF) distributes uniformly; and each high-strength bolt (HSB) primarily delivers vertical shear force. However, the stress in the CSF redistributes when the walls develop into the elastic... words:precast shear wall; vertical joint; seismic behavior; high-strength bolt; connecting steel frame......
rock mass and frame beam with pre-stressed anchor cable. Furthermore, the conception of the best anchorage-angle in pre-stressed anchor cable was proposed. At last, the parameters of the interaction between transverse isotropy rock mass and frame beam with pre-stressed anchor cable were investigated by finite element method, and the best anchorage-angle in pre-stressed anchor cable was obtained......
