When building finite element analysis model, the authors make the following hypothesis: ①after electrodes contact with lithium-ion battery poles, there is no longer any relative motion; ② the driving force F2’ equably exerts on the contact surface where the head of electrode clamps connected with driving boards. ③the material of electrode clamps are isotropic.
A couple of clamp deformation figure and its stress distributing graph As is shown in Fig 5, when Δs is 0.5mm, the electrodes grip the poles, the maximal stress occurs on point A, the value is 169.49Mpa, while the yield strength of 55Si2MnB is 1176 Mpa, the maximal stress is much smaller than the yield strength of the material.

Abstract.
According to Gordon [1], the major cause for soils to become acid are rainfall and leaching, acidic parent material, organic matter decay and also harvest of high yielding crops.
The process of soil acidification takes place when the subsoil or parent material containing acidic ion was exposed to the atmosphere.

The XRD patterns for all samples were measured at the “Structural Materials Science” beamline [9] in the Kurchatov Synchrotron Radiation Centre (Moscow, Russia).
Taking in to account the weight concentration (3 %) of iron oxide introduced to our glass composition, we can estimate the FR value observed to be comparable with data of Ref. [11], what allows considering them as a perspective material for the magneto-optical applications.
This difference reflects the particles anisotropy which can include several contributions: crystal anisotropy of nanoparticles material, surface anisotropy, the shape anisotropy, anisotropy of the nanoparticles interaction, etc.
