The utility model discloses a footboard linkage mechanism and body builder, and relates to the field of body building equipment. Its technical scheme includes: stress structure, and this structure contains the first rotary joint part of rotatable connection with external support structure, and its both sides are equipped with first force connecting part and first linkage connecting part respectively; footboard unit, including footboard; guide unit, and footboard linkage; first linkage structure, between stress structure and footboard, when the stress structure rotates with the first rotary joint part as the axle, first linkage structure drives footboard to move in the range of guide unit limit. Advantageous effects are: realize the linkage of crouching action and footboard, make shank and foot at the ankle joint place always be in the close vertical range during training, reduce the ankle joint injury probability, and can complete the maximum degree crouching simultaneously, distribute the training resistance as much as possible to the target hip muscle group, improve training efficiency greatly.

A bio-based coordination-type foam dust suppressant, its preparation method, and its application belong to the field of dust control technology. The bio-based coordination-type foam dust suppressant comprises the following components in parts by weight: 10-30 parts sodium alginate, 1-8 parts α-hydroxycarboxylate, 0.2-2 parts coordination intermediate stabilizer, 6-20 parts lauryl alcohol, 3-15 parts dodecyl vinyl ether, 2-5 parts ethylene glycol laurate, 1-2 parts isopropyl myristate, 2.5-10 parts dodecyl diethylene glycol ether, 1-10 parts dodecyl carboxylate, and 50-200 parts water. The bio-based coordination-type foam dust suppressant of this invention possesses coordination charge regulation capability, good biodegradability, and excellent foam stability, enabling efficient dust suppression.

The application discloses a solution containing natural macromolecule and a coagulation molding method. The fiber stream obtained by wet spinning of the solution containing natural macromolecule is coagulated and molded through at least one coagulation bath. The solution containing natural macromolecule contains metal hydroxide and an additive selected from at least one of urea, zinc oxide and thiourea. Bicarbonate or bisulfite or a combination of bicarbonate and carbonate or a combination of bisulfite and sulfite is used as a component of the coagulation bath. The low-cost, green, efficient, non-toxic, harmless and inexpensive inorganic salt solution does not contain strong acid and organic solvent, and can be used to prepare long fibers with circular cross section and excellent mechanical properties. The long fibers have smooth surface, softness and luster. In the coagulation bath, the bicarbonate and carbonate or the bisulfite and sulfite can be easily separated and recovered.

According to the high-strength and high-plasticity FeNiAl eutectic high-entropy alloy and the preparation method thereof, through the collaborative design of B microalloying, homogenization, cross cold rolling deformation and medium-temperature heat treatment optimization, a fine and uniform eutectic lamellar structure and a high-density dislocation structure are formed in a plate, the brittleness brought by an as-cast coarse structure is effectively relieved, and the high-strength and high-plasticity FeNiAl eutectic high-entropy alloy is obtained. The tensile strength and the yield strength are remarkably improved, meanwhile, high ductility and fracture resistance are kept, and the performance anisotropy caused by the rolled texture is further weakened. The technological process is simple, parameters are easy to control, and the method is suitable for industrial amplification application and is suitable for high-temperature structural parts, molds, impact load components and other scenes with high requirements for comprehensive mechanical properties of materials.

This invention discloses a pea peptide, its preparation method, and its application, belonging to the technical field of plant polypeptide preparation and application. A mixture of sodium bicarbonate and sodium alginate is sprayed onto pea protein powder, and then dried at 70-80℃ for 3-5 hours. The dried pea protein powder is mixed with water to obtain a mixed solution, which is then heated to 45-55℃. Alkaline protease is added for enzymatic hydrolysis, and papain is added to the hydrolysate for further hydrolysis. After hydrolysis, enzyme inactivation is performed. The hydrolysate is filtered, concentrated, and spray-dried to obtain the pea peptide. The pea peptide prepared by this invention has a high recovery rate, low free amino acid content, and more than 85% of the molecules with a molecular weight less than 600 Da. It also exhibits high enzymatic hydrolysis efficiency, short hydrolysis time, and good antioxidant activity.
