Abstract: Disclosed is a set of adhesive adapters containing sample barcodes for specifically tagging different samples. Further disclosed is a method for simultaneously detecting CpG methylation in a high number of samples, which is multi-sample reduced-representation bisulfite sequencing (msRRBS); and an alternative method thereof, which is multi-sample reduced-representation APOBEC sequencing (msRRAS). The adapters are used to specifically tag the plurality of samples, including all DNA fragments of the plurality of samples; then the plurality of samples are pooled to allow a single-tube reaction of the plurality of samples; and then the subsequent conversion, sequencing library construction and sequencing, distribution and decoding of readings of each sample, and downstream analysis are conducted. The library construction technology of the present application has advantages such as high efficiency, low cost, and stable and convenient operations.

Abstract: Disclosed are a household appliance, an apparatus and a method for detecting an arc fault in the household appliance. The apparatus includes: a grid current detecting unit, configured to detect a current from a power grid to the household appliance so as to generate a first current detecting signal; a filter protecting unit, configured to perform an attenuation processing on an arc signal in the power grid; a load current detecting unit, configured to detect an actual running current in a load of the household appliance so as to generate a second current detecting signal; and a control unit connected to the grid current detecting unit and the load current detecting unit respectively, and configured to identify and compare the first current detecting signal and second current detecting signal so as to determine a source of the arc fault.
