摘要:Abstract(#br)A series of composites composed of 3C–SiC nanoparticles and metal oxide is fabricated by direct dispersion. Some vibrational modes observed from the 3C–SiC nanoparticle-based nanocomposites exhibit significant red shifts whereas other modes exhibit blue shifts, ...

摘要:Abstract(#br)It is well known that there would be stress singularity different from 1 / r near a notch tip or an interfacial edge, and there may be even multiple or oscillatory singularities. The fracture evaluation for such a case is somewhat difficult due to the arbitrary singu...

摘要:Abstract(#br)By introducing effective fatigue stresses, multi-axial fatigue problems can be transformed into equivalent uni-axial problems. A damage evolution law has been proposed from the view of cyclic motion of atoms׳ balance position, and the life evaluation formula has...

摘要:Abstract(#br)The impact of a low frequency MHD mode crash on triggering the H-mode has been studied in detail on the HL-2A tokamak. The mode manifests fishbone characteristics with a precession frequency f ≈ 14 – 19 kHz . The abrupt mode crash evokes substantial energy relea...

摘要:Abstract(#br)A nominal strain energy density of interface has been introduced to represent the deformation state of interface. By assuming that there are deformation capacities for volume and distortional deformation energy of interface, the interfacial fracture criterion fo...

摘要:Abstract(#br)Well-sampled optical and radio light curves of BL Lacertae in B , V , R , I bands and 4.8, 8.0, 14.5 GHz from 1968 to 2014 were presented in this paper. A possible 1.26 ± 0.05 yr period in optical bands and a 7.50 ± 0.15 yr period in radio bands were detected ...

摘要:Abstract(#br)In recent decade, deficits in the mechanism of Supervisory Attentional System (SAS) have become increasingly influential in explaining the nature of dysexecutive syndrome experienced by schizophrenic patients. The SAS model is characterized by having a detailed ...
