The invention provides a codominant SSR (simple sequence repeat) marker closely linked with a tobacco xanthophyll gene qXant and an application method of the codominant SSR marker. The serial numbers of the codominant SSR marker closely linked with the tobacco xanthophyll gene qXant are TMy82029 and IDYK01541, and the nucleotide sequences of PCR (Polymerase Chain Reaction) amplification products of the codominant SSR marker closely linked with the tobacco xanthophyll gene qXant are respectively shown as SEQ ID No. 1, SEQ ID No. 2, SEQ ID No. 3 and SEQ ID No. 4. The application is the application of the codominant SSR marker closely linked with the tobacco xanthophyll gene qXant in detecting whether the tobacco xanthophyll gene qXant exists in a tobacco genome DNA (Deoxyribose Nucleic Acid) or not. Compared with a method in the prior art, the codominant SSR marker has the characteristics of accuracy, high efficiency, stability, convenience, low cost and no detection opportunity limitation, so that the molecular marker can be applied to molecular marker-assisted selection of the lutein gene qXant in tobacco breeding.

This utility model discloses an elevator guide shoe wear detection mechanical probe assembly, including a detection mechanical probe body with a guide shoe threadedly fixed to its lower end and rubber pads fixed to three sides of the inner side of the guide shoe; a prediction component, which includes a connecting block welded to one end of the detection mechanical probe body, rectangular grooves symmetrically opened on both sides of one side of the connecting block, a threaded hole in the middle section of the rectangular groove, a detection probe threadedly fixed to the middle section of the connecting block, and an observation ruler threadedly fixed in the rectangular groove; and a reminder component, which includes a central fixing block fixed to one side of the upper end of the rubber pad, a torsion spring fitted inside the fixing block, and rotating blocks fixed to both ends of the torsion spring. This utility model, through its prediction component, can quickly and intuitively detect whether the elevator guide shoe is misaligned or tilted, causing the detection mechanical probe to malfunction, thus improving maintenance efficiency, enhancing safety performance, and preventing personal injury.

The present invention relates to the field of cable detection, and specifically to a method for identifying cracks in a cable and its insulation layer. A transient simulation model is set and verified with actual samples, and the components of a first comprehensive magnetic field in the X-axis and Y-axis directions are evaluated, and the changes of the two at different speeds are comprehensively considered to obtain a standard speed for better detecting cracks in the cable. Subsequently, a second cable sample is used to obtain the position of a wave crest in an eddy current to set the relative position of an excitation coil and a probe module in an eddy current probe, so that cracks can be detected more clearly. Finally, a third sample is set to obtain two standard crack intervals for detecting cracks in the cable, so that the position of the crack in the cable can be quickly detected when detecting cracks in batches of cables, which is convenient for employees to evaluate and repair. The problem that the crack detection error is larger when the cable speed is larger due to the influence of eddy current and comprehensive magnetic field traction is solved.

The invention discloses an integrated biological photoelectrode with an active noise reduction function. The integrated biological photoelectrode with the active noise reduction function comprises a light emitting diode, an active noise control line and at least one microelectrode. By arranging the light-emitting diode and the microelectrode, the nerve cells can be subjected to light stimulation through the light-emitting diode, so that the nerve cells move to generate nerve impulse signals, and the nerve impulse signals are collected through the microelectrode to be processed, analyzed and studied; by arranging the active noise control line, an electric signal can be applied to the active noise control line, so that the noise influence generated when the light emitting diode works is counteracted, the active noise reduction function is achieved, and it is guaranteed that the integrated biological photoelectrode detects clearer signals. The method is widely applied to the technical field of biosensing.
