Objective Establishes through the experiment normally with the arsenic poison optic nerve tension stress-strain relational expression,results in data and so on stress,strain,load,displacement,for studies the arsenic poison looking at each other nerve the influence to provide the biological mechanics parameter.Methods Is poisoned normally with the arsenic big mouse optic nerve each 10,can on the testing machine carry on the stretch experiment in the electronic side.Under 36.5 ℃±0.5 ℃;By the 5mm/min experimental speed to the test specimen infliction stretch load,after the experiment ended the printer to print the load,the displacement,the stress,the strain data and the curve automatically.Results The normal control group optic nerve biggest load is 1.79 N±0.09 N,the biggest displacement is 2.52 mm ±0.21 mm,the biggest stress is 4.66 MPa±0.24 MPa,the biggest strain is 62.8 %±5.1 %,the arsenic poison group biggest load is 1.48 N±0.30 N,the biggest displacement is 2.08 mm±0.16 mm,the biggest stress is 3.84 MPa±0.20 MPa,the biggest strain is 52.1%±4.02%.Conclusions The stress-strain curve is by the index relations change,the arsenic poison animal optic nerve mechanics characteristic has the change.
