摘要： A method of predicting at least one physical change in crack geometry of a crack in a pipeline based on in-line inspection operating pressure is presented. In one method, a first test on a pipeline is performed at a first pressure, which obtains a first set of test data. A second test is performed on the pipeline at a second pressure, obtaining a second set of test data. The first and second sets of test data are compared for any difference. A run comparison software processing device may be employed. In other methods, finite element analysis of crack-like dimensions is performed to predict Crack Mouth Opening Displacement (CMOD) for a given set of crack dimensions for a surface-breaking crack and inline pipe inspection operating run pressure. Another method predicts probability of detection of a crack associated with a given CMOD as a function of pressure in successive inspections.

摘要： A backlight control circuit includes a logic unit, a drive unit, a decoder, a current setting unit, a current stabilizer, a pulse width modulated generator, a plurality of light sources, and a control unit. The control unit controls the brightness of each light source according to the pulse width modulated signals from the pulse width modulated generator.

According to a decoded signal from the decoder, the current setting unit sends a second control signal and an output voltage to the current stabilizer, the current stabilizer generates a steady current.

摘要： Water-cooling U-valve is composed of a downcomer (1), a riser (2), and a return chute (3), which are sequentially connected. An intermediate partition (4) is disposed between the downcomer (1) and the riser (2), the lower parts of which are interconnected. A material returning partition (5) is disposed between the riser (2) and the return chute (3), the upper parts of which are interconnected. The casing of U-valve is membrane walls, the inside of which are laid with refractory. Some water-cooling tubes of the membrane walls extend into the inside of the U-valve, forming the water cooing intermediate partition (4) and material returning partition (5). There are headers (40, 50) for both the intermediate partition (4) and the material returning partition (5), and the headers (40, 50) are connected with the headers (33, 13) formed by some water-cooling tubes of membrane walls by connecting tubes (7, 8). The invented U-valve can guarantee that there is no expansion difference between the partitions and the casing, which can extend the working life of the partitions and realize the long-term safe and stable operation of the U-valve.
