The application discloses an application of an animal domestication behavior related RRM1 gene mutant. Through population genetics, comparative genomics and ancient genomics analysis, the cause variation of the strongest selected gene of goat domestication, namely, the RRM1 gene c.1020A>G mutation, is determined; through association analysis with a hybrid population with wild goat blood, it is found that the mutation is significantly related to the domestication behavior in the goat domestication process; and through construction of a mouse containing the RRM1 gene c.1020A>G mutation, it is proved that the corresponding mutant of the RRM1 gene obviously increases the domestication behavior of the mouse. The application provides a basis and lays a foundation for phenotype selection of the domestication behavior and preparation of a tame animal model.

The utility model discloses a soil sample temporary storage tank for land reclamation, which comprises a bottom support, the upper surface of the bottom support is fixedly connected with a bottle body, the top end of the bottle body is in threaded connection with a bottle cap, and a protection component is arranged in the bottle body. According to the soil sample temporary storage tank for land reclamation, through cooperation of the bottom support, the bottle body, the bottle cap and the protection assembly, the volume of the cavity bag can be expanded after air pressure in the cavity bag is increased, the inner wall of the cavity bag can be attached to a soil sample placed in the bottle body, and then the stability of the soil sample in the bottle body in the transportation process can be improved; the collapse probability of the soil sample in the transportation process can be reduced, subsequent effective detection of the soil sample is facilitated, meanwhile, residual air in the bottle body is discharged into the cavity bag, the air allowance in the bottle body is greatly reduced, the water amount generated by air gasification in the bottle body can be reduced, the probability that water flows into the soil sample is reduced, and the water quality is improved. And accurate obtaining of subsequent detection results is facilitated.

The invention discloses a domain adaptive adversarial open set cross-domain intelligent fault diagnosis method, which relates to the field of mechanical intelligent fault diagnosis, and comprises the following steps: respectively constructing a feature extractor, a private class classifier, a first auxiliary classifier and a second auxiliary classifier; training a private class classifier and a feature extractor by using an adversarial training method so as to obtain good classification performance of shared classes of a source domain and a target domain, and establishing a boundary for the shared classes and the private classes in the target domain; and maximizing the prediction divergence of the first auxiliary classifier and the second auxiliary classifier so as to detect excluded outlier target domain shared class samples and forcibly generate target feature representations similar to the source domain features. The invention also discloses a domain adaptive confrontation open set cross-domain intelligent fault diagnosis system. According to the method, the private class samples of the target domain can be identified as the unknown class while the shared class samples of the target domain and the source domain are aligned, and the method has relatively high cross-domain intelligent fault diagnosis accuracy in an open set fault diagnosis scene.
