Abstract:
1) Briefly introduce some basic information on the astronomy in China.
2) The measurements of solar magnetic fields and the relevant questions at Huairou Solar Observing Station in China.
3) From observations of solar vector magnetic fields to some questions on the non-potentiality of magnetic field and helicity.

Annular kinematic segmentation of galaxy disks
Joan Font
Instituto de Astrofísica de Canarias, La Laguna, Tenerife, Spain
Abstract:
Our technique (“FB”) for the precise measurement of corotation radius, based on using the phase change by π of the radial component of stellar or gas motion expected at this radius, has recently been compared with the classical Tremaine-Weinberg method showing complete agreement where both could be applied. However FB is more generally applicable and can be used over complete galaxies, from the innermost zones with nuclear bars to the outermost spiral arms. When this is done, the result is to uncover more than one corotation radius per galaxy. In this talk I will present the main results of applying our method to samples of disk galaxies, barred galaxies, double barred galaxies and barred spiral galaxies.
