Abstract: The present disclosure relates to a method for microscopic examination of phytoplankton. The present disclosure solves the problem of decreased counting accuracy of perioptometry in a dry environment. The method is as follows: step 1, making an analyte into a glass slide, performing qualitative identification of the phytoplankton in the field of view; and step 2, drying the glass slide; after drying, counting the phytoplankton and full-slide rare algae on the glass slide microscopically. When the humidity of microscopy room is only 20%, the method of the present disclosure may count a sample accurately, which has a significant increase in counting accuracy compared with the existing perioptometry. The method of the present disclosure effectively solves the problem of failure to perform the perioptometry accurately due to dry ambient humidity.

Abstract: The disclosure provides a method for fast reconfiguration of power supply grid in tens of milliseconds after power grid failure. The master station of fast reconfiguration of power grid concentrates the network status information from the client stations at transformer substations or power plants, and compares it with the built-in control strategy table which deals with possible faults. When an expected power gird disconnection fault is detected, the pre-start switch-on instruction is sent to the client stations with multiple breakers which can reconnect the grid. When the fault is cleared, the client stations shall identify the fault clearing time according to the local information, and send the instruction of synchronous switch-on to the corresponding local breakers which can reconnect the separated grids.
