The optical fiber cable connects to the one optical engine.

The invention discloses an immune lateral chromatography detection method and device for carrying out external drive on a biomarker. The device comprises immune lateral chromatography test paper consisting of a bottom liner 1, a sample pad 2, a combination pad 3, an analysis membrane 4 and a water absorption pad 5, wherein the analysis membrane is provided with a detection belt 6 and a quality control belt 7; the device further comprises an upstream drive electrode 8 and a downstream drive electrode 9; the upstream drive electrode is connected with the end part of the upstream outer side of the sample pad; the downstream drive electrode is connected with the end part of the downstream outer side of the water absorption pad. According to the method disclosed by the invention, strong and uniform external drive force generated by the electrodes is used as a power source to carry out external drive on surging of the biomarker, so that the precision, the accuracy and the detection speed ofvarious existing immune lateral chromatography technologies are greatly improved; on the basis, the detection sensitivity is improved through promoting release of the biomarker.

The invention discloses a floating sizing die, which comprises an upper template, an upper die cutter block, a lower template, a lower die cutter block, a guide part and a floating sizing cutter block transversely arranged between the upper die cutter block and the lower die cutter block. Negative angle forming parts which are matched and used for generating negative angles by extruding a U-shaped punching piece are arranged on the upper die cutter block, the lower die cutter block and the floating sizing cuter block. The U-shaped punching piece is sleeved on the negative angle forming parts of the floating sizing cuter block. By adopting the technical proposal, the problem of incapability of producing the U-shaped punching piece with the negative angle in the prior art can be well solved; the die is simple in structure and high in production efficiency and capable of punching and forming at one time; the accumulative tolerance caused by fractional assembly can be avoided; the product precision is increased; the tooling number is reduced; the process is shortened; and the production cost and the production and quality control difficulty can be reduced.

A preparation system of a panel rock-fill dam bedding material comprises a coarse crushing segment. A first screening segment, an intermediate crushing segment, a second screening segment and a fine crushing segment are arranged below the coarse crushing segment. A main screening segment is arranged below the fine crushing segment, and an ultra-fine crushing segment is arranged below the main screening segment. A first-grade finished bedding taking point is arranged behind the intermediate crushing segment. A second-grade finished bedding taking point is arranged behind the fine crushing segment. A third-grade finished bedding taking point is arranged behind the ultra-fine crushing segment. Finished bedding materials taken from the three grades of finished bedding taking points are all conveyed to a finished product stock dump through a belt conveyor. Under treatment of the effective crushing and screening technology, gradation compositions of materials at all joints in the technology process are controlled, the upstream and downstream multi-grade technology joints are selected as the taking points along with the technology process, and the cost of the finished bedding materials is greatly reduced by means of four segments of crushing and three grades of finished bedding material taking; and the first part and the second part are long-gradation continuous mixtures, a mixing link generated in the stacking, taking and transporting process is gathered into a subsequent sealing-tape machine, and the quality control difficulty is reduced.

The invention relates to the field of engineering machinery, and discloses a method and device for calibrating the displacement current of a pumping pump and construction machinery. The method includes determining the initial displacement current of the pumping pump; In the case of the pumping pump and the displacement of the pumping pump being controlled by the initial displacement current, determine the pumping times of the pumping pump in the pumping cycle; determine whether the determined pumping times are in the within the range of preset pumping times; and in the case that the determined pumping times are not within the preset pumping times range, updating the initial displacement current until the determined pumping times are within the preset pumping times Send within the range of times to complete the calibration of the displacement current. In this way, the automatic calibration of the displacement current is realized.
