This invention provides a transistor metal connection wire reliability on line test method, which comprises the following steps: using the transistor cutting channel test circuit and exerting test voltage on any point of the test circuit comb circuit; testing the leakage current between the connection wires of the comb circuit; step by step increasing the test voltage, if the leakage current tested is small and the voltage is basically stable, which means the metal transistor connection wire electric characteristic has good reliability, otherwise, there is some problems existing.

The invention provides a scale type micro-fluidic chip for quantitative immediate diagnosis and a preparation method of the scale type micro-fluidic chip. The scale type micro-fluidic chip comprises micro-reaction chambers and micro-channels, wherein the micro-reaction chambers have sample feeding holes and sample discharging holes, openings at one ends of the micro-channels are communicated to external environments, and indicating liquid is locally encapsulated in the micro-channels; scale marks and corresponding numerical values are arranged outside the micro-channels to facilitate the quantitative reading of a detection result, the other ends of the micro-channels are communicated with the micro-reaction chambers through buffer tanks to form complete independent working units, and meanwhile, multiple working units can be arrayed on a chip to realize multichannel detection. The scale type micro-fluidic chip has the advantages of no complex instruments, convenience in carrying, low cost, simplicity and convenience in operation, easiness in reading, multi-target detection, little use amount of sample, sensitivity and the like and can be widely applied to biochemical analysis fields including medical diagnosis, food security, environmental pollution and the like.

A Brillouin distributed optical fiber sensing based structural joint monitoring device is characterized by comprising steel plate bases (9), a linear steel sheet (5) and an L-shaped steel sheet (8) are mounted on each steel plate base (9), a pulley (6) is mounted at each of a suspension arm end of each linear steel sheet (5) and a corner end of each L-shaped steel sheet (8), an optical fiber (1) for stretching detection is wound on the two corresponding pulleys (6) at the suspension arm ends of the linear steel sheets (5) on two sides of a structural joint, an optical fiber (2) for contracting detection is wound on the two corresponding pulleys (6) at the corner ends of the L-shaped steel sheets (8) on two sides of the structural joint, an optical fiber (3) for temperature compensation detection is connected between the optical fiber (1) for stretching detection and the optical fiber (2) for contracting detection, and each of the optical fiber (1) for stretching detection and the optical fiber (2) for contracting detection is connected with a Brillouin distributed optical fiber demodulating system through a respective connecting optical fiber (4). The Brillouin distributed optical fiber sensing based structural joint monitoring device is capable of monitoring the stretching quantity and the closing quantity of the structural joint, achieves temperature self compensation and effectively overcomes the shortcomings when the optical fibers are simply laid.
