It’s necessary to stack fixed end force; While finite element method mainly bases on the known load and the material nature of structure after structure discretization.
Finite element method firstly divides structure into limited discrete units according to the loading and the nature of the material.

The following reactions occur: The anode reaction: Fe -2e→Fe2+ E0 (Fe2+/Fe)= -0. 44 V The cathodic reaction: 2H++2e→2[H]→H2 E0 (H+/H2)=0. 00 V When O2 is present: O2+4H++4e→2H2O E0(O2)=1. 23 V O2+2H2O+4e→4OH- E0 (O2/OH)=+0. 40 V The iron and carbon occurred internal electrolysis reaction in the solution, and iron is easy to form Fe2+ after dissolved in the acidic solution, Fe2+ has strong reduction for the azo dyes, which makes the macromolecules dye dissociated to low molecular weight material, and also has decolorization effect.
The biological carbon has the unique surface and physical and chemical properties of good adsorption materials.

The frequency range of AE, a transient elastic wave under material deformation, is usually 100kHz-1MHz and its displacement is 10 -10-10-13m.
While the AE in a real structure is emitted from the inside of material, the AE in PLF is emitted on the surface of material.
The resonant frequency depends on both the length of a cantilever and material properties of an optical fiber.

Materials like chemigum, polypropylene, polythylene, polyvinyl in the equipment and pipeline (if any) should be replaced by stuff such as fluorated polyethylene, fluorated polypropylene, teflon.
The parts material is suggested to be replaced by teflon or copolymer of ordinary rubber and TFE.
The original copper, plastic and rubber sealing elements (like the plastic washer of delivery valve, seal washer of oil return pipe and fuel oil delivery line), if possible, should be substituted by aluminum or teflon material.
