The present invention is related to a thin film semiconductor which can be regarded as substantially a single crystal and a semiconductor device comprising an active layer formed by the thin film semiconductor. At least a concave or convex pattern is formed intentionally on a insulating film provided in contact with the lower surface of an amorphous silicon film, whereby at least a site is formed in which a metal element for accelerating crystallization can be segregated. Therefore, a crystal nuclei is selectively formed in a portion where the concave or convex pattern is located, which carries out controlling a crystal diameter. Thus, a crystalline silicon film is obtained. A crystallinity of the crystalline silicon film is improved by the irradiation of a laser light or an intense light having an energy equivalent to that of the laser light, whereby a monodomain region in which no grain boundary substantially exit is formed.

The invention discloses a hydraulic system for hydraulic rock drill testing. The hydraulic system comprises a hydraulic oil tank, a check valve C, a hydraulic pump, an overflow valve, a reversing valve, a liquid control one-way valve, an impacted oil cylinder, a one-way valve, a check valve D, a pressure sensor, a pressure gauge and a gravity energy accumulator. When the system is used for testing a hydraulic rock drill, an impacted piston is subjected to rock drill impacts, a balance weight block in the gravity energy accumulator ascends by a certain height under the action of hydraulic oil, and the impact energy of the hydraulic rock drill is measured according to the ascending height of the balance weight block. Energy equivalent to the ascending height of the balance weight block can be calibrated and converted according to a heavy hammer with the fixed height. The check valve D in a system loop can be opened, and the durable running test of the rock drill can be conducted. The system is applicable to testing of performance of various hydraulic rock drills different in power, operation is simple, and calculation is convenient.

The invention discloses a prediction method of automobile active safety system effectiveness on the basis of collision deformation depth. The prediction method comprises the following steps: 1) determining an automobile group with similarity rigidity; 2) determining a relationship between EES (Energy Equivalent Speed) and the deformation depth and the relationship between the deformation depth and an injury risk; and 3) establishing an accident reconstruction database, building a control system to carry out accident simulation, combining the relationship between the EES and the deformation depth with the relationship between the deformation depth and the injury risk, calculating and comparing whether the injury risk of the safety system in an accident scene is in the presence or not, and obtaining whether the safety system is effective in improving automobile safety through a comparison result. The prediction method discusses and looks forwards a way of utilizing a deformation degree to predict the automobile active safety system effectiveness on an aspect of the reduction of passenger injury risks only on the basis of the accurate deformation degree information in the accident database. Compared with a method which utilizes speed information, the prediction method disclosed by the invention can obtain more accident data support and more comprehensively evaluates the automobile active safety system.

The invention provides a method for quantitative detection of nugget crack by using energy equivalent of an acoustic emission signal in a resistance spot-welding process. The method comprises the following steps: acquiring a structural load acoustic emission signal of the resistance spot-welding process in real time, drawing a dynamic oscillograph; extracting the acoustic emission signal of the crack; counting amplitude distribution; dividing the amplitude into a plurality of grades Mi, and accumulating according to ringing count Ni of the acoustic emission signals exceeding each amplitude grade, respectively, to obtain the log value log10Ni of the ringing count, so as to obtain a splattering distribution diagram; fitting a straight line to form a right triangle, calculating out the area, so as to obtain the energy equivalent of the corresponding resistance spot-welding nugget crack; setting an energy equivalent threshold value, determining an acoustic emission source to be a low-energy acoustic emission source when the energy equivalent is lower than the threshold value, and determining the acoustic emission source to a dangerous crack acoustic emission source when the energy equivalent is higher than the threshold value. Due to the adoption of the method, the grade and size of the resistance spot-welding nugget crack defect can be evaluated relatively exactly and quantitatively, and the rapid and nondestructive detection for the nugget crack is realized.
