Research on the Servo Loading Systems of High Aspect Ratio Wing Test

open access: yesHangkong gongcheng jinzhan, 2019
It occurs that the loading point changes with the test piece in the aircraft structure test. In particularly, the large deformation of the wing will cause the issue that loading point is not perpendicular with the plan of the wing.

Test of the QCD vacuum with the sources in higher representations [PDF]

open access: yes, 2000
Recent accurate measurement by G.Bali of static potentials between sources in various SU(3) representations provides a crucial test of the QCD vacuum and of different theoretical approaches to the confinement. In particular, the Casimir scaling of static
