The invention discloses a method for strengthening joint stability by using an rhBMP-2 release coating on the surface of an artificial joint, which relates to a method for strengthening the joint stability. The invention solves the problem that a function of inducing the bone formation of BMP-2 is difficult to realize in the whole process of forming a new bone by using a method of combining an HA coating and the BMP-2 on the surface of the traditional artificial joint, and the action time of the release is not controllable by using a method of combining the BMP-2 and polyethylene glycol. The method comprises the following steps of: 1, adding EC and PEG 4000 into chloroform, ultrasonically dissolving the EC and PEG 4000, adding BMP-2 and carrying out ultrasonic dispersion to obtain a BMP-2 mixed liquid; and 2, spraying the BMP-2 mixed liquid on an artificial thighbone steam, placing the artificial thighbone steam in an ultra-clean working table to air, packaging into a seal bag, and sterilizing the seal bag at a low temperature to complete the process. The invention has the advantages of even and tight combination of the rhBMP-2 release coating and the joint surface, smooth coating layer, difficult damage, strengthened stability of the artificial joint and adjustable release performance.

The invention relates to an exterior wall glass-fiber reinforced concrete coping type installation method. The exterior wall glass-fiber reinforced concrete coping type installation method is characterized in that fabrication in sections is conducted on a glass-fiber reinforced concrete line according to an on-site actual size, coping type installation is conducted, a joint is reserved, and the joint is set as a visible joint surface which is sealed through silicone adhesive. The exterior wall glass-fiber reinforced concrete coping type installation method has the advantages that the firmness of the line installation can be effectively strengthened, and the phenomenon of water leakage is effectively avoided; in the process of line installation, on one hand, the installation speed is increased, and the joint strength is improved; on the other hand, the phenomena of excess materials and waste materials and the like rarely occur, and the construction cost is greatly reduced.

The invention relates to an organic film solar battery element as well as a forming method and a manufacturing method thereof. The organic film solar battery element at least comprises a semiconductor film layer with a rough surface. The semiconductor film layer with the rough surface can be a P type semiconductor layer or an N type semiconductor layer, and a rough appearance is generated on a joint surface of the P type semiconductor layer and the N type semiconductor layer.
