The invention discloses an ion implantation system. The system comprises an ion source and an extractor, wherein a mass analyzing magnet, a correcting magnet and a workpiece scanning device are arranged on the transmission path of the ion beams in sequence. The system also comprises a scanning magnet arranged on the upper stream of the correcting magnet and a beam current measuring device arranged in the implantation position, wherein the scanning magnet is used for scanning the passing ion beams so as to ensure distribution of the ion beams which are arranged in the implantation position and in the preset energy range in the ion beam scanning direction to cover the workpiece; and the beam current measuring device is used for measuring the intensity and angle distribution of the beam current in the scanning direction of the ion beams. The invention also discloses an ion implantation method realized by the ion implantation system. The system and the method have the following positive effects: accurate control of the implantation angle uniformity and implantation intensity uniformity of the ion beams can be realized; the production cost is lowered; and the process flows are simplified.

The invention provides a vehicle component (1, 26, 36, 82) in the form of a trim part, body part, or bumper. The vehicle component (1, 26, 36, 82) forms at least one housing part (2, 28, 38, 84) for an emitter (4, 50).

The invention relates to a steel pipe punching and shearing machine which is particularly suitable for machining the end parts of steel pipes in T-shaped connectors of steel pipe railings of ladder platforms for electric power and constructional engineering construction, and belongs to the technical field of mechanical equipment. The steel pipe punching and shearing machine comprises a support auxiliary system (1), a locking device (2), a knife rest device (3), a transmission device (4) and a pressure rod (5) and can shear the side pipe wall of a pipe (7); as an improvement, the steel pipe punching and shearing machine further comprises a shifting block device (6); a cam plate (403) is adjusted into an outer cam through a first shifting block device (601), the pressure rod (5) is pressed down so as to drive the cam plate (403) to rotate, and a transmission plate (401) and a transmission plate (402) are driven to move through a movable shaft (409) so as to drive a sliding knife rest (302) to move downwards to complete shearing of the pipe wall at the lower side of the pipe (7); and the pressure rod (5) is reset, the cam plate (403) is adjusted into an inner cam through a second shifting block device (602), the pressure rod (5) is pressed down, and the pipe wall on the upper side of the pipe (7) is sheared. According to the steel pipe punching and shearing machine, the punching and shearing operation of the end parts of the steel pipes with various pipe diameters can be completed, machining and forming can be realized at a time, and therefore the pairing efficiency and the welding quality of the T-shaped connectors of the steel pipe railings can be improved.

The invention discloses a cement concrete curing method which is characterized in that: concrete shrinkage reducing solution is directly sprayed or coated on the concrete surface during curing process; when no liquid shrinkage reducing solution remains on the concrete surface, concrete curing agent is sprayed on the concrete surface. In the method, the shrinkage reducing solution is firstly sprayed, and then the concrete curing agent is sprayed, therefore the efficacy loss situation caused by mutual interference of the shrinkage reducing agent and curing agent is avoided, the volatilization of shrinkage reducing agent and the water dispersion of concrete interior are prevented after the curing agent is filmed, and the concrete shrinkage and crack prevention effects are further reinforced;compared with prior art, the cement concrete curing method effectively prevents the concrete shrinkage and crack, reinforces the cement hydration effect and improves the curing effect.
