The invention discloses a method for reinforcing structures through a method of externally pasting a reinforced concrete frame with ductility column energy dissipators, and belongs to the field of reinforcement of concrete structures. The reinforced concrete frame with the ductility column energy dissipators is externally pasted on the outer side of an original reinforced concrete frame structure. The intensity grade of the concrete and the intensity grade of the reinforcing steel bars of a newly added frame beam and those of a newly added frame column are higher than those of an original frame beam and those of an original frame column, and the intensity grade difference should not exceed two. The newly added frame beam and the newly added frame column are connected with the original frame beam and the original frame column respectively through an adhesively bonded anchorage mode. The adhesively bonded anchorage mode is achieved through the fact that embedded steel bar glue is implanted by drilling anchor bars to be fixedly connected with original frame concrete. The anchor bars and the newly added frame structure are cast in situ. Each reinforced concrete ductility column energy dissipator comprises a reinforced concrete ductility column and rigid supports at the two ends of the corresponding reinforced concrete ductility column. The intensity grade of the concrete and the intensity grade of the reinforcing steel bars of the reinforced concrete ductility column energy dissipators are identical to those of the newly added frame. The reinforced concrete ductility column energy dissipators and the newly added reinforced concrete beam are integrally cast in situ. The method is quite beneficial to reinforcement effects.

The invention provides a flexible extensible joint device for a cross fault tunnel lining in strong earthquake area and a tunnel lining structure, and relates to the field of transportation infrastructure. The flexible extensible joint device for the cross fault tunnel in high intensity earthquake area is able to maintain the safety and stability of the structure under the condition of static load. A variable structure is become under the fault dislocation and strong ground motion to achieve the transverse, vertical and circumferential deformation in a tunnel, so that a tunnel structure can follow the ground motion displacement on the degree of freedom, and the influence of the forced dislocation displacement and ground motion displacement on a lining structure is reduced. The stiffness ofthe tunnel structure itself is not weakened, and the earthquake damage caused by the mismatch between the lining structure and the stiffness of a flexible joint is reduced, so that the safety is guaranteed. The tunnel lining structure can ensure normal use function under the action of fault forced dislocation or strong ground motion, a damaged flexible extensible device assembly is quickly replaced and quickly restored, and the smooth passage of life is guaranteed.

The invention belongs to the technical field of fruit and vegetable preservation and particularly relates to a fruit and vegetable preservative, fruit and vegetable preservative paper and a method for preparing the fruit and vegetable preservative paper by using the fruit and vegetable preservative. The fruit and vegetable preservative consists of the following components in percentage by mass: 97.85 percent to 98.5 percent of starch, 0.5 percent to 0.65 percent of acrylate, 0.5 percent to 0.85 percent of nano silica and 0.5 percent to 0.65 percent of nano titanium dioxide. The fruit and vegetable preservative paper with the fruit and vegetable preservative takes bamboo fiber paper as a carrier, wherein the fruit and vegetable preservative is adhered onto the bamboo fiber paper. The fruitand vegetable preservative, the fruit and vegetable preservative paper and the method have the advantages that the humidity of a fruit and vegetable storage space can be reduced, bacteria can be sterilized, mold can be prevented, the air cleanness can be improved, the preservation effect is excellent, the repetitive use can be realized and the cost is low.

The invention belongs to a plant beverage for improving the constitution of patients with hyperglycemia and diabetes mellitus. The beverage is prepared from the following raw materials in parts by weight: 1-50 parts of kudzu vine root, 1-60 parts of Chinese yam, 1-70 parts of malt, 1-50 parts of polygonatum kingianum, 1-60 parts of rhizoma phragmitis, 1-50 parts of semen ziziphi spinosae, 1-50 parts of fructus mume, 100-2000 parts of erythritol and 1000-50000 parts of water. The plant beverage has the advantages of integral recuperation under medical treatment, safety without toxicity, good blood glucose reduction effect, unique flavor and good taste, and can be used for effectively reducing the blood glucose of patients with diabetes mellitus and improving the constitution of patients with hyperglycemia and diabetes mellitus.

The invention relates to a spring made of novel materials and a manufacture method thereof, and aims at providing a corrosion-resistant polytetrafluoro ethylene (PFA) spring and the manufacture method thereof. The PFA spring is made of PFA, and the manufacture method comprises the following procedures: 1 choosing a PFA tube with required tube diameter, and cutting the tube into sections with proper length; 2 fixing the cut PFA tube on a fixture, and cutting the tube into spiral strip shapes through a blade; 3 winding the spiral PFA strips on a sizing lead screw, placing the strips into an oven, setting the temperature to be 250 degrees and baking for 2 to 3 hours; and 4 taking the spiral PFA strips out from the oven, and placing the spiral PFA strips into pure water for cooling. Accordingly, the PFA spring is obtained.
