A series of and co-doped phosphors, whose features qualify them for consideration in white-light UV or blue light-emitting diodes (LEDs), was synthesized via a high temperature solid-state reaction under reductive atmosphere. The dependence luminescence properties the produced powders on concentration an activator coactivator investigated. experimentally recorded spectra calculations efficiency energy transfer from to critical distance between suggest resonance-type energy-transfer mechanism...
The rectifier transformer is the power of equipment. characteristic device AC input, DC output by rectifying original. Converter and voltage regulation connect through oil gas casing Shanxi medium aluminium Huarun Co., Ltd. In order to solve problems such as high test current caused 200 kW no-load loss, insufficient capacity single frequency conversion supply, complicated field environment, great interference, a complete plan presented according conditions field, whole process successful...
To resolve the problem of ductile fracturing beam flanges in traditional connections with concrete-filled steel tube columns using site-welded side plates, an alternative connection design requiring minimal site welding was designed and studied. An explicit analysis method, considering fracture strain criterion developed by stress triaxiality path, adopted to study seismic performance resistance proposed connection. The results a verified finite-element model indicated that flange never...
Serve earthquake often cause large deformation to structures which might deteriorated or degraded seismic performance level. Installing shape memory alloy (SMA) dampers the structure is one of most effective approaches mitigate disasters. The mechanical behaviour superelastic Ni-Ti wire tested and a multi-linear constitutive model appropriately describes elucidates property material characteristics obtained by simplifying hysteretic response. A new axial type SMA damper with energy...
Cyclic loading tests on superelastic and plastic yielding shape memory alloy (SMA) wires are conducted to investigate the phenomena of superelasticity (SE) degeneration yielding.Parameters influencing mechanical properties SMAs investigated variation tendencies discussed.The results indicate that both SE in SMA affected by cyclic numbers; The wire exhibits severe phenomena; Superior is demonstrated wire.
Summary An innovative self‐centering‐energy‐dissipation device (SCED) based on a superelastic shape memory alloy (SMA) is developed. This exhibits asymmetric, flag‐shaped hysteretic behavior and tension–compression symmetry property. The attributed to the tension‐only state of SMA wires in during loading process. working principle described, theoretical model describing mechanical properties proposed. Uniaxial cyclic tests are carried out investigate influence section area wire, amplitude,...
