摘要： The application provides an access control method of parallel direct current power supplies and a device thereof. Direct current power supplies with single insulation resistances to ground failing to meet a first preset condition or causing a total insulation resistances to fail to meet a second preset condition are disconnected from a grid-connected inverter, and direct current power supplies with single insulation resistance to ground meeting the first preset condition and enabling the total insulation resistance to meet the second preset condition are connected with the grid-connected inverter for grid-connected inverting. Unlike in conventional technology, not all the direct current power supplies connected to a direct current bus are made stop outputting, thereby avoiding the loss of inverter power generation.

摘要： A gene expression data classification method and a gene expression data classification system are provided. With the gene expression data classification method, a gene feature data set is acquired, and then the gene feature data set is clustered using a clustering algorithm to obtain clustering sets, the number of which is a first preset parameter, the clustering sets are processed to obtain a second sample matrix, a second training set and a feature index set, to reduce dimensionality of gene expression data. In this way, redundancy among the gene expression data is reduced, thereby greatly reducing calculation resources and calculation time consumed in a subsequent process of performing feature selection on the second training set. Also, a few calculation resources and a little calculation time are consumed in a case of clustering the gene feature data set by using the clustering algorithm, therefore, a few calculation resources and a little calculation time are consumed by classifying the gene expression data to be measured with the gene expression data classification method.
