The invention discloses a multi-pose lower-limb rehabilitation robot and a use method thereof, and belongs to the field of medical apparatuses. The rehabilitation robot comprises a pedestal, a liftingmechanism and a bed body which are arranged sequentially from bottom to top; a pair of thigh training mechanisms and a pair of leg training mechanisms are symmetrically arranged on the two sides of the bed body correspondingly; the thigh training mechanisms and the leg training mechanisms are used for performing lower-limb rehabilitation training on a patient whose lower limbs have dyskinesia; the patient is subjected to lower-limb rehabilitation training by multiple modes; furthermore, the bed body and a seat cushion are overturned, so that training of three poses of sitting, lying and standing can be realized, the training mode is comprehensive and the training effect is good. By the method adopting the multi-pose lower-limb rehabilitation robot, the training effect is excellent.

One embodiment of the present invention provides a thermoplastic resin composition comprising: (A) a grafted acrylic copolymer; (B) an aromatic vinyl-cyanovinyl copolymer; and (C) a polyalkyl (meth)acrylate resin. The aromatic vinyl-cyanovinyl copolymer (B) can comprise 5-25 wt% of a monomer derived from a cyanovinyl compound.

The invention relates to a wear-resistant hydraulic-oil additive composition with excellent anti-emulsifying property for a lubricating oil additive composition of a hydraulic transmission system, belonging to the technical field of a lubricating oil additive. The wear-resistant hydraulic-oil additive composition comprises an extreme-pressure anti-wear agent containing sulfur, an anti-wear agent containing phosphorus, a metal deactivator, a detergent, an anti-rusting agent and an antioxidant. The raw material contains the following components in percentage by weight: 5-20 % of extreme-pressure anti-wear agent containing sulfur, 20-55% of anti-wear agent containing sulfur, 1-10% of metal deactivator, 5-20% of detergent, 2-5% of anti-rusting agent, 12-25% of antioxidant, and the balance of base oil, and the sum of the percentage of all the components is 100%. The additive composition adopts the existing mannich amine detergent usually used in the gasoline detergent to replace polyisobutylene succinimide, alkaline calcium sulfonate and a magnesium detergent used in the traditional lubricating oil additive, and obviously improves the anti-emulsifying property of industrial wear-resistant hydraulic oil.

The present invention provides a gallium nitride based semiconductor light emitting diode having high transparency, and at the same time, capable of improving contact resistance between a p-type GaN layer and electrode and a process for preparing the same. These objects can be accomplished by forming, on an upper part of a upper clad layer made of p-GaN, an ohmic contact forming layer using MIO, ZIO and CIO (In₂O₃ including one of Mg, Zn and Cu), and then a transparent electrode layer and a second electrode with ITO thereon, so as to improve contact resistance between the upper clad layer and the second electrode while providing high transparency.

The invention relates to the field of preparation processes for tempered films, in particular to a tempered film and a preparation method thereof. The preparation method includes the following steps:S1, rough shape cutting; S2, CNC fine carving; S3, thorough sweeping; S4, ultrasonic cleaning; S5, tempering; S6, coating of anti-fingerprint oil; S7, drying; and S8, bonding via AB glue. The temperedfilm has the beneficial effects that the thin tempered film has better structural strength, and can meet both the requirement for protecting the structural strength of a mobile phone screen and the use requirement of a user.

The invention discloses a glass ceramic crystallization method and device. The crystallization method comprises melting, calendaring molding, roller-bed coring, tin-pond crystallizing, roller-bed annealing, cutting and batching out, wherein the crystallization device comprises a tin pond brick through beam, a tin pond top cover brick, a heating element, a lifting device, a tin pond, a front transition roller bed and a rear transition roller bed, one end of the lifting device is fixedly mounted at the bottom of a cross beam, the other end of the lifting device is connected with the tin pond topcover brick, the heating element is connected with the bottom of the tin pond top cover brick, a crystallization tin pond is arranged at the lower part of the heating element and comprises a tin pondbottom brick, a tin pond wall brick and a tin pond breast wall, and the front transition roller bed and the rear transition roller bed are respectively arranged on the two sides of the tin pond. Thethree-step heating melting method and the three-step calendaring molding method greatly improve the transparency, the toughness, the compressive strength and the crack resistance of a glass sheet; theroller-bed coring is adopted, then the high-temperature conveying of the glass sheet is facilitated, and the roller-bed coring is favorable for the even heating of the glass sheet; and the tin-pond crystallizing improves the flatness of the surface of the glass ceramic glass sheet.

The invention relates to a polymethyl methacrylate and polycarbonate composite board which comprises a polymethyl methacrylate layer. The upper layer and the lower layer of the polymethyl methacrylatelayer are respectively covered with an upper polycarbonate layer and a lower polycarbonate layer; the polymethyl methacrylate layer is attached to the matte surface of the joint surface of the upperpolycarbonate layer and the lower polycarbonate layer in a thermal attachment manner; the invention relates to a preparation method of a polymethyl methacrylate and polycarbonate composite board. Thepreparation method comprises the following steps: (1) respectively heating and melting polycarbonate and polymethyl methacrylate raw material particles in different preheaters; (2) respectively extruding polycarbonate and polymethyl methacrylate from different channels of the multilayer die head; (3) carrying out three-roller calendering molding on the extruded polycarbonate and polymethyl methacrylate; and (4) laminating and cutting a polycarbonate and polymethyl methacrylate composite board finished product.
