The invention relates to a measuring method and a measuring platform for biomechanical performance parameters of in vitro corneas. The measuring method comprises the following steps: 1, fixing a cornea sample and spraying powder; 2, continuously exerting pressure to deform the cornea sample and recording a pressure value; 3, recording the variations of intervals of powder particles; 4, computing the three-dimensional deformation in each area of the surface of the cornea sample; 5, computing the biomechanical performance parameters through a general constitutive equation. The measuring platform comprises a mounting platform, wherein a cornea fixing device is mounted on the mounting platform and provided with an inner chamber; a clamping end for clamping the cornea sample is arranged at one end of the inner chamber; the other end of the inner chamber is connected with a pressure unit; shooting equipment is arranged at the front end of the cornea fixing device; the pressure unit is connected ...

A system for improving saline-alkali soil through industrial carbon dioxide comprises an industrial waste gas treatment system, a liquid carbon dioxide storage device, a carbon dioxide water dissolving device, a drip irrigation system and a salt discharging device. The method for reducing carbon and increasing yield by using the system comprises the following steps: 1) preparing industrial carbon dioxide with the purity of not less than 95% by using the industrial waste gas treatment system; 2) dissolving industrial carbon dioxide gas in water by using a gas water dissolving device to form an acidic aqueous solution; (3) applying the acidic aqueous solution into crop root layer soil by using a drip irrigation system to neutralize alkali metal ions in the soil so as to form bicarbonate easy to flow; and 4) discharging the eluent containing the bicarbonate out of the soil by using a salt discharging device.

According to the saline-alkali soil improvement method, before autumn turning in the first year, 4.5-7.5 t/hm < 2 > of composted cow dung, 6.75-11.25 t/hm < 2 > of composted chicken manure, 70-80 kg/hm < 2 > of urea and 15-30 kg/hm < 2 > of potassium fulvic acid are applied in a broadcast mode, and 8.44-14.06 t/hm < 2 > of desulfurized gypsum is applied to ditches with the depth of 2.5-7.5 cm along a drip irrigation zone during sowing in the second year. After the method is used, the salt content of the soil is reduced. Particularly, when the under-film drip irrigation rice is planted on the saline-alkali soil, the yield is remarkably increased after the method is used, and the appearance quality of the rice is greatly improved.
