Introduction The guitar’s quality is directly affected by chords’ thickness, density, length and speakers’ materials and shape.
This paper assumes guitar speaker’s structure and materials are ideal value, only having finite element analysis on chords, on the basis of chords vibration theory analysis, using the finite element method to analyze the chords inherent frequency, and compared with the theory the results.

Determining the Contact Angle of Hardened Cement Paste Using Thin Layer Wicking Method Qian Tiana, Hang Zhang, Yujiang Wang, Fei Guo, Ting Yao and Jiaping Liu State key Laboratory of High performance Civil Engineering Materials, Jiangsu Research Institute of Building Science aemail tianqian@cnjsjk.cn Keywords: Contact angle, cement paste, superplasticizer, thin layer wicking method Abstract.
The thin layer wicking method based on wash washburn dynamic method for measuring the contact angles of powdered materials was successfully applied to all minerals, even those with irregular shapes, including nonswelling clays, dolomite, basalt, limestone, a variety of silicates, etc[2-7].
Then, the solid material is penetrated by non-spreading liquids, in which case cosθ<1.
One end of the degreasing cotton was dipped into the liquid, and the other was touched to the end of the thin layer in the starting moment of the penetration process The chambers were made of transparent PMMA materials, so the moving boundary of the ethanol liquid penetrating the thin layer is visible.
