The application discloses a kind of gastrointestinal early cancer pathological specimen auxiliary observation devices, including bottom plate, the mounting seat of detachable connection for outside specimen containment and to the specimen is fixed and the mounting structure for adjusting mounting seat on the relative position of bottom plate in the width direction of bottom plate and mounting seat is fixed on the bottom plate, the frame plate is erected at both ends of the bottom plate, sliding rail is arranged between two frame plates, the length direction of sliding rail is consistent with the length direction of bottom plate, sliding block is movably arranged on the sliding rail along the length direction of sliding rail, and endoscope assembly for outside observer to observe the specimen in mounting seat is arranged on the sliding block, the fixing assembly for fixing and limiting sliding block after sliding is arranged on the sliding rail.The application solves the problem that the volume of traditional gastrointestinal early cancer postoperative specimen observation device is too large, operation is inconvenient, and the cost is too high due to too many electronic components and parts.

The invention discloses a carbonate rock slice quantitative lithofacies identification method, and relates to the technical field of petrology analysis and image processing.The method is based on a microscope and an image processing technology, integrates rock specimen observation, slice preparation and rock structure analysis, performs layered labeling on slice scanning images through vector mapping software, and obtains a slice sample; the pixel proportion, namely the area proportion, of the rock structure is counted through ImageJ software, quantitative analysis of the rock structure is completed, and high-precision quantitative analysis of mineral components, structure types and pore parameters can be achieved. Through automatic quantitative analysis, the problems that traditional identification depends on subjective experience and is low in efficiency are solved, the precision and the standardization level are remarkably improved, and the method is suitable for oil and gas geological survey, reservoir evaluation and carbonate rock formation cause research.

The water bath box comprises a water bath box body, a control surface is installed at the position, close to the bottom end, of the front face of the water bath box body, the top end of the water bath box body is open, a cover plate is clamped at the top end of the water bath box body, and an isolation assembly is arranged at the position, close to the bottom end, of an inner cavity of the water bath box body. The isolation assembly comprises a limiting flange, a partition plate and a through hole, a test tube rack is placed on the top end face of the partition plate, and the test tube rack is used for storing specimen test tubes; the holding rod and the connecting rope are matched with the first hook and the second hook, so that when a sample needs to be taken out, a worker only needs to hold the holding rod and lift the holding rod upwards, the test tube rack can be lifted from water in the water bath box body, and the test tube rack can be stably hung after the test tube rack comes out of water by matching with the second hook; therefore, the test tubes on the test tube rack can be conveniently taken out to observe specimens.

A specimen observation assistance device is provided with an observation position display unit, a display processing unit, a representative image registration processing unit, a coordinate conversion processing unit, an input device monitoring processing unit, and a condition control unit. The input device monitoring processing unit acquires the position of the cursor, acquires stage coordinates associated with the representative image on the basis of the position of the cursor, and displays the stage coordinates on an observation position display unit while controlling the representative image to a size that is easily visible. The condition control unit performs processing so as to move the stage of the charged particle beam device to stage coordinates associated with the representative image.

The application discloses a microscope-based biological experiment operation evaluation method and device and readable medium, wherein the method comprises the following steps: acquiring and processing the light-focusing image of the microscope in the biological experiment operation, performing edge detection on the processed light-focusing image to obtain edge information and determine the state of the positioning circle in the light-focusing image; acquiring the component state detected by the light-focusing operation component detection sensor, determining the light-focusing step operation result according to the state of the positioning circle and the component state; acquiring the specimen observation image of the microscope at different times in the biological experiment operation and processing the specimen observation image, obtaining the black-and-white pixel point proportion and Gaussian blur difference value according to the processed specimen observation image, and calculating the clarity factor; acquiring the trigger state detected by the focusing operation component trigger sensor, and determining the observation step operation result according to the change process of the clarity factor corresponding to the specimen observation image at different times and the trigger state. The method can reduce the computer computing power requirement and reduce the deployment cost.

This invention discloses a method for processing the wingspan of Diptera spp. (Cryptospiridae), including steps of pre-softening, moisturizing, wing shaping, drying, and fixing. The processed wingspan can be preserved for a long time in the air and can be used for specimen observation and photography. It provides important evidence for photographing samples and recording the microstructure of wing veins, and as evidence, it can provide an important morphological basis for future research, providing evidence for species identification and identification of similar species, playing an important role in scientific research and rapid identification.
