Cultivation method of selenium-enriched pleurotus geesteranus

The invention discloses a selenium-rich pleurotus geesteranus cultivation method, which comprises cultivation material stirring, bagging, sterilization, inoculation, cultivation, fruiting management, disease and pest control and picking, selenium salt is added into the cultivation material, and the selenium salt is added after being prepared into gel microspheres. Selenium salt is released in three different concentrations and is uniformly absorbed, the suitability and stability of the selenium content in pleurotus geesteranus sporocarp are ensured, no selenium residue exists, the selenium conversion and utilization capacity is high, in addition, modified calcium carbonate is added into the cultivation material to serve as a pH regulator, and the yield of the pleurotus geesteranus is improved. The stability of the selenium content in the sporocarp and the selenium conversion and utilization capability are further promoted.

Distributed system-oriented multi-component fault interpretation method and device

The invention discloses a multi-component fault interpretation method and device for a distributed system. The method comprises the following steps: acquiring historical operation data of a plurality of to-be-detected components from a distributed system; training a feature representation network based on a step-by-step attention mechanism, and obtaining an optimal network weight when the value of the hypercircle cost function is minimum; constructing an online fault interpretation network model by using the optimal network weight; constructing a classification decision rule based on majority voting; and taking k nearest neighbor fault samples as explanations of the to-be-detected fault samples. According to the fault interpretation scheme provided by the invention, the historical fault sample most similar to the to-be-detected fault can be accurately found, and a feasible elimination scheme is provided for the to-be-detected fault sample by taking the historical fault sample as a reference ...
