A Graphical Approach for Human Skin Moisture Evaluation by Electrical Impedance Spectroscopy Yuxing He1,a, Yonggui Dong2,b 1,2State Key Laboratory of Precision Measurement Technology and Instruments, Department of Precision Instruments and Mechanology, Tsinghua University, Beijing 100084, People’s Republic of China aheyuxing01@126.com, bdongyg@mail.tsinghua.edu.cn Keywords: skin moisture evaluation; graphical approach; electrical impedance spectroscopy; Abstract: A pair of concentrically placed gold electrodes is utilized in contact with human skin surface for moisture evaluation.
As this probe will be used in a dry-contact way with the skin, the measuring surface(the inner circle and the outer ring) is covered with gold material to protect the surface and reduce electrode polarization effect.

Sichuan Higher Education Engineering Research Center for Disaster Prevention and Mitigation of Village construction, Dujiangyan 611830, China Key words: deep-buried small net distance tunnel, full-face excavation method, benching tunneling construction method, both side heading method, numerical analysis Abstract.
Besides, it can supply better theoretical basis to similar engineering design and construction.
（2）The deep-buried tunnels with small net distance under engineering geological condition, both side heading method is better than full-face excavation method and benching tunneling construction method for controlling the deformation of intermediate surrounding rock, stress amplitude , stress concentration of surrounding rock and displacement restrictions, therefore, we recommend this scheme.
