Functional magnetic resonance imaging （fMRI） technique has been more widely applied to related studies of acupuncture central integration mechanisms with the advantages of non-invasion and real-time monitor, etc. Discovery of resting state brain activities and the default brain network challenges to the acupuncture-related studies based on traditional block design. The paper reviews some obvious advances of fMRI in studies of acupoint specificity, and research methods and progresses of the resting state brain functional network in recent years, and raises the thinking about leading the resting state fMRI and the brain functional network into acupuncture-related studies, in the hope of probing into the effect and modulation of acupuncture on the default network, promoting development of acupuncture mechanism studies and strengthening scientific basis of acupuncture and moxibustion theories.

This paper reports the high-energy proton irradiation effects on GaAs/Ge space solar cells. The solar cells were irradiated by protons with energy of 5-20 MeV at fluence ranging from 1×109 to 7×1013 cm-2, and then their electric parameters were measured at AM0. It was shown that the Isc, Voc and Pmax decrease as the proton energy increasing, and the degradation is relative to proton irradiation-induced defect with a level of Ec-0.4. eV in irradiated GaAs/Ge cells.

The orientation of the dimple increases the flow distance in the dimple and produces fluid cumulative effect in the dimple length direction, which leads to obvious hydrodynamic effect as a result. In order to investigate the hydrodynamic effect of orientation dimples, a series of experiments was carried out on a ring-on-ring test. Multi-pored faces were tested with different dimple inclination angles and slender ratios. Film thickness and frictional torque were measured under different conditions of load and rotation speed. Experimental results showed that the orientation dimple could produce obvious dynamic effect by change of the flow direction and the increasing dimple orientation leads to increase of the load capability. The hydrodynamic effect strongly depends on dimple orientation parameters such as inclination angle and slender ratio. A larger load capability can be available by increasing dimple orientation and rotation speed. Experimental results agreed well with the theory that orientation micro-pores can significantly improve hydrodynamic performance of surfaces.
