Abstract: The present invention relates to the fields of microorgan-isms, feed, food and ecological restoration, in particular to a strain for degrading deoxynivalenol (DON) and the use thereof. The strain has the deposit number CCTCC No. M 2020565. The strain can grow by means of taking the toxic compound DON as a sole carbon source, and convert the DON into chemical components for itself. The reaction process is irreversible, the reaction conditions are moderate, and secondary pollu-tion cannot be caused. The strain provided in the present invention can be used for preparing a biological detoxification preparation for DON. The strain provided in the present invention can be used for degrading DON in feed and food raw materials, primary processing products, deep processing products and related processing byproducts. The strain provided in the present invention can be applied to various ecosystems such as soil or bodies of water polluted by DON to achieve the purposes of DON degradation and ecological restoration.

Abstract: A method for rock identification includes the steps of receiving a rock slice image transmitted by an image acquisition device, generating a geometric feature, a mineral feature and a structural feature corresponding to a rock slice based on the rock slice image, and generating an identification result of the rock slice based on the geometric feature, the mineral feature and the structural feature. After the rock slice image is obtained, the rock slice image is subject to feature extraction based on three dimensions, i.e., the geometric feature, the mineral feature and the structural feature, the properties of rock are determined based on multiple dimensional features, and finally the identification result comprising a textual description is generated. After a microscopic visual image corresponding to the rock slice is obtained, feature extraction based on multiple dimensions is performed on the image, and the rock slice is identified with reference to multi-dimensional features.

Abstract: A method of sampling ingredients of an oil-bearing inclusion includes a) providing a first container and a second container, an external diameter of the first container being smaller than an internal diameter of the second container, and the first and second containers both being transparent; b) adding a solvent into the first container and sealing said first container; c) adding an oil-bearing inclusion sample into the second container, and putting the first container that contains the solvent and is sealed in step b) into the second container; and d) using a laser to ablate the oil-bearing inclusion sample contained in the second container that is sealed in step c), and using the laser to break an end portion of the first container close to the sample on condition that the second container is maintained complete, so as to allow the solvent in the first container to enter the second container.
