Abstract: A breeding method for rapidly stabilizing cotton distant hybridization progeny is disclosed. It belongs to the technical field of plant breeding. The disclosure is based on VSG (G. barbadense semi-compatible material) as female parent, general G. hirsutum materials as male parent of the cross to get F1 generation of G. barbadense-G. hirsutum hybrid materials, and treats the F1 generation of young bolls with 0.03-0.05% of colchicine aqueous solution to induce F2 generation to separate the stable intermediate materials or new varieties with excellent genes of both G. barbadense and G. hirsutum, so as to produce new cotton germplasm resources. The main innovation of the present disclosure lies in that it changes the previous treatment position and method of colchicine on cotton plant, and the disclosure is not limited by haploid and directly treats the cotton bolls on F1 cotton plants.

Abstract: A method for training isolation forests includes: acquiring a plurality of categories by classifying uniform resource identifiers; acquiring sample behavior data by monitoring a behavior of a client from each of Internet Protocol IP addresses in a plurality of IP addresses accessing the uniform resource identifiers under the plurality of categories; encoding the sample behavior data as a sample access vector; and training, based on the sample access vector, an isolation forest for recognizing a web crawler from the client.

Abstract: The present disclosure provides an apparent resistivity-depth section generating method for short-offset electromagnetic exploration, including: determining, in field zones divided quantitatively based on the induction number, positions of a recording point for each of observation points and frequencies or a time window thereof; and taking determined positions of the recording point as the assignment point for the observation point and the frequencies or the time window thereof, where one survey line of an axial configuration generates one apparent resistivity-depth section along the survey line; and one survey line of an equatorial configuration typically generates one apparent resistivity-depth section along the survey line, and apparent resistivity-depth sections along connecting lines from the observation points to the source which are the same as observation points in the number.
