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 equipment installation, and particularly discloses a pit edge mounting base and a construction method, which comprises a pre-buried plate, the pre-buried plate is installed on the bottom of the inner wall of a pouring groove arranged at the edge of a pit body, a supporting piece is fixedly installed on the pre-buried plate, a guard angle steel is installed on the top of the supporting piece, the top of the guard angle steel is flush with the top of the pouring groove, an angle steel supporting lug is fixedly connected to the side of the guard angle steel close to the pit, a gap is formed between the upper surface of the angle steel supporting lug and the upper surface of the guard angle steel, and the gap is used for mounting a pit cover plate; the pre-buried plate is used for connecting the structure of the pit foundation, the top of the pre-buried plate is provided with a civil engineering formwork during the civil engineering process, so that the pre-buried plate can be effectively leveled through the civil engineering formwork; and the pre-buried plate is arranged in a plane, after pouring the foundation, no protrusion is formed, and compared with the inclined steel bar used as the pre-buried piece, the safety hidden danger of tripping the installation personnel is eliminated.

This utility model discloses a shower pipe fixing structure. It includes a suction cup base and a sleeve for mounting the shower pipe. The suction cup base comprises a base body, a turntable, and a suction cup made of soft rubber. The suction cup is located at the bottom of the base body, and a raised ear is provided at the center of the suction cup. A shaft passes through the ear. The turntable is rotatably mounted on the base body. The center of the turntable is located within the base body and has a clearance hole. Two centrally symmetrical arc-shaped bosses are provided on the turntable at the clearance hole. One side of each arc-shaped boss has a slope. The two ends of the shaft are respectively placed on the slopes of the two arc-shaped bosses. The sleeve is fixedly connected to the base. This utility model uses a suction cup to fix the pipe to the wall, eliminating the need for drilling and nails, protecting the wall surface. Furthermore, the suction cup is secured directly by rotating the turntable, further optimizing operation and making it simpler and easier to use.
