Quantum criticality in the iron pnictides and chalcogenides

open access: yes, 2011
Superconductivity in the iron pnictides and chalcogenides arises at the border of antiferromagnetism, which raises the question of the role of quantum criticality.

平面连杆机构摆动力完全平衡的质量矩替代法

open access: yesJixie chuandong, 2000
This paper improves the mass moment substitution method for shaking force complete balancing of planar linkage. The basic thought is that the shaking force complete balancing of planar linkage is reduced to the mass moment substitution of two pairs link ...
