The present application relates to a kind of spectral analysis system and method, specifically, a kind of laser-induced breakdown spectroscopy analysis system and method based on suspended electrode and filter paper.The system includes filter paper, adjustable sample stage, high-voltage discharge device, suspended electrode, laser ablation device and spectral signal acquisition and analysis device.The present application uses suspended electrode to change the distribution characteristics of high-voltage electric field, increase local electric field line density and electric field intensity, improve the collision frequency of charged particles in plasma, so as to further enhance the detection sensitivity of LIBS to trace elements, and reduce its detection limit.High-voltage discharge device is used to excite laser plasma again, to improve the detection and analysis ability of target elements.Filter paper enrichment method is used for pretreatment of the sample to be measured, which can effectively reduce the interference of liquid matrix on plasma spectral signal, and improve the sensitivity and stability of detection signal.

The application relates to the technical field of mine mechanical equipment, and provides an underground multifunctional carrier vehicle, which comprises a main vehicle frame, a directional caster wheel arranged at the front end of the main vehicle frame, a rotary connecting rod, one end of the rotary connecting rod being rotationally connected with the main vehicle frame, a split vehicle frame, the split vehicle frame being connected with the other end of the rotary connecting rod, and a universal caster wheel arranged at the connecting end of the split vehicle frame and the rotary connecting rod. In a first mode of the split vehicle frame, the split vehicle frame is rotated and folded around the rotary connecting rod, the split vehicle frame and the main vehicle frame are parallel and superimposed, the universal caster wheel is lifted and suspended and is accommodated in the inner side of the directional caster wheel, and the directional caster wheel independently supports the main vehicle frame. In a second mode of the split vehicle frame, the split vehicle frame is rotated and unfolded around the rotary connecting rod, the split vehicle frame and the main vehicle frame form a preset included angle, the universal caster wheel falls and supports the main vehicle frame together with the directional caster wheel. Through the rotary deformation structure between the main vehicle frame and the split vehicle frame, function integration and conversion are realized.

This invention discloses a design method for an all-steel radial railway tire. The tire has a centrally symmetrical cross-section and includes an external contour structure, an internal contour structure, and the thickness of key components. The method includes the following steps: S1: Determine the tire's outer diameter and end face width, and calculate the tire's section height based on the outer diameter; S2: Design the external contour structure, which includes the crown contour line, shoulder contour line, sidewall contour line, and bead contour line; S3: Design the thickness of key components, which include the crown, shoulder, sidewall, and bead; S4: Design the internal contour structure, which includes the inner contour arc of the crown, shoulder, sidewall, and bead. After determining the tire's outer diameter and section width, the remaining parameters can be automatically calculated using coefficients. The entire process is not only time-efficient but also reduces the requirements for designers.
