Thus, the pure bending deformation equation of beams can be directly used in mechanics of materials.
QSn4-3 has good processing properties and electrical conductivity, easy melting and low cost [7], so it’s the main materials of mechanical instruments and hairspring measurement.
Characteristics of the materials used to manufacture hairspring are given in Table.1.

Mechanical properties index of the material.
Mechanical properties index of the material are shown in Table 2 and the steel bars are grade one with the diameter of 6mm.
Four displacement transducers were placed at two side faces and strain gauges were attached to U-shaped tie bars and surfaces of specimens in order to measure deformation and strain of the material.

Secondary battery chemistries beyond lithium-ion, such as sodium-ion batteries (SIBs), have been intensively investigated these days because of the natural abundancy of sodium raw materials [1-2].
Raman spectra for all the GPEs as well as for the raw materials were recorded by using RAM II FT-Raman module connected to a Bruker Vertex 70 FTIR spectrometer with a laser wavelength of 1064 nm.
Fig.3 shows the Raman spectra for all the six GPE compositions as well as for the raw materials.
