The invention relates to an automatic sample preparation system of electric steel. The system comprises a shearing system (1) which comprises a punch (101), a first fixture (102), and a first screw propulsion system (103). The punch (101) is arranged in front of a running bulk sample (5) of the electric steel; the first fixture (102) is used for clamping the rear end of the running bulk sample (5) of the electric steel; the first screw propulsion system (103) is driven by a first step motor (104); the punch (101) and the first step motor (104) are controlled by an industrial control computer. The automatic sample preparation system of the electric steel uses the screw propulsion system to transmit the bulk sample of the electric steel so as to punch and slice; the screw propulsion system operates in pauses according to the set width of the industrial control computer; the sampling speed is high; and the slicing is highly accurate.

The invention discloses a method for preparing a micron-scale particle transmission electron microscope sample, which includes the following processes in a focused ion beam-scanning electron microscope dual-beam system: selecting sample particles of the order of micron size to be measured; applying an ion beam The deposition process deposits the first material on the outer surface of the sample particle to form a protective layer covering the sample particle; welding the sample particle covered with the protective layer to the sample carrier net; The sample particles covered with the protective layer are cut to form a test sample with a thickness on the order of nanometer size on the sample carrier. The method can simplify the sample preparation process of micron-sized particle transmission electron microscope samples, increase the speed of sample preparation, and increase the success rate of sample preparation.

The invention relates to a device and a method for preparing an undisturbed soil sample of a ring cutter. The device comprises a work table, a support column, a soil sample lower backing plate, a force transmission frame, a pressing head, a lever, a spring clip and other common tools for preparing the soil sample, wherein the preparation materials can be steel, aluminum, alloys and the like. By utilizing the device and the method, the original sample of the ring cutter is prepared under a condition that a sample box is not completely opened, so that an opportunity that the soil sample is damaged in the preparation process of the sample is effectively reduced; for soil samples of loess, cracked clays and the like which are easily cracked, the ring cutter sample with high quality can be prepared, and the sample manufacturing success ratio is high and the scrap ratio is low; and for sand soil with low cohesive force, the original sand soil sample can be sampled by a common soil taking device so as to further prepare the undisturbed soil sample of the ring cutter.

The invention discloses a sample preparation method for quantitative analysis of water elements based on a laser induced breakdown spectrum. The method includes the steps that S1, a metal substrate not containing to-be-detected elements is acquired, the surfaces of the metal substrate are polished, and the upper surface and the lower surface of the metal substrate are made parallel; 2, filter paper is cut, wherein the area of the cut filter paper is smaller than that of the surfaces of the metal substrate; S3, the cut filter paper is placed on the polished surfaces of the metal substrate, to-be-detected liquid drops drip on the filter paper on the surfaces of the metal substrate, and the filter paper is heated; S4, after heating is completed, the filter paper is removed, and a heavy metal containing dry sample which is evenly distributed and consistent in diffusion range is acquired on the surfaces of the metal substrate. The filter paper serves as an intermediate conversion layer of the liquid drops and the metal substrate, even diffusion of the liquid sample is achieved through the even hole diameter of the filter paper, the diffusion range of liquid is limited through the fixed size of the filter paper, and sample preparation is easy to control and good in repeatability.

The invention provides a soil cutting and segmenting device for cohesive soil. The soil cutting segment device for cohesive soil includes: a bottom plate; a fixed plate, the bottom of which is fixed on the top of the bottom plate; top, and is located on one side of the fixed plate; push block, the bottom of the push block is slidably connected to the inner surface of the sample conveying groove; the sample is sent into the push rod, and the sample is sent into the push rod One end is fixed on one side of the push block; a support frame, the bottom of the support frame is fixed on the top of the bottom plate. In the soil cutting and segmenting device for cohesive soil provided by the present invention, the sample is pushed into the sample conveying groove by the sample push rod, cut by the cutter and stored in the sampling sleeve, pushed out by the sample push rod, etc. For the work of hard plastic and hard cohesive soil, the sample preparation speed is fast, the segmentation is uniform, the quality is guaranteed, the structure is simple, and the operability is strong.
