Abstract: A method for driving a display panel, a method for debugging a display panel, and a storage medium. The method for driving a display panel includes acquiring target black insertion ratios corresponding to a display frame, dividing the display frame into display sub-frames that each include a black insertion stage in which the target control signal is at a non-enable level and a light-emitting stage in which the target control signal is at an enable level, and providing the target control signal obtained based on the target black insertion ratios to the display panel. The target black insertion ratios includes black insertion ratios that respectively correspond to the black insertion stages of the plurality of display sub-frames in the display frame, and at least two of the black insertion ratios that correspond to at least two of the black insertion stages are different from each other.

Abstract: A low-carbon urban land layout optimization simulation method includes establishing a land layout optimization scheme by determining the objective function and constraint conditions of the adjustable land layout optimization; the objective function includes the first objective function to achieve low-carbon transportation, the second objective function to reduce the urban heat island effect, and the third objective function to control and adjust the carbon cost; the vector plot with internal nested grid points is used as the simulation analysis unit, and the genetic algorithm is used to simulate the land layout optimization scheme. In the simulation process, the simulation analysis unit is used to select, cross, and mutate in the genetic algorithm, and finally, the optimal land layout scheme is selected. The method uses the global and holistic characteristics of a genetic algorithm to screen out the optimal land use layout scheme.

Abstract: Disclosed are a base station and a cleaning equipment. The base station includes: a first box defined with a sewage inlet for solid-liquid mixed garbage to enter the first box; a second box communicated with the first box, for receiving liquid garbage from the first box; a cyclone separator communicated with the first box; and a fan communicated with the cyclone separator, the fan is configured to drive an external airflow into the first box from the sewage inlet, and drive the external airflow to enter the fan after passing through the cyclone separator, such that the solid-liquid mixed garbage enters the first box through the sewage inlet.

Abstract: Disclosed are an air duct assembly and a cleaning device. The air duct assembly comprises a dirt collecting box, a filter, a cyclone separator and a fan. The dirt collecting box is provided with a dirt collecting cavity and the dirt collecting box is also provided with a dirt inlet and an air outlet communicated with the dirt collecting cavity. The filter is arranged in the air outlet, the cyclone separator is connected with the air outlet, and the fan is connected with the cyclone separator. The fan drives an air flow to enter into the dirt collecting cavity from the dirt inlet, and enter the cyclone separator from the air outlet after being guided, and then enter the fan from the cyclone separator.

Abstract: A composite organic binder and methods for preparing and using the same are disclosed. The composite organic binder is made of the following components in mass percentages: 0.97-1.13% of polyethylene oxide and 98.87-99.03% of a papermaking sludge. The composite organic binder could solve the problems of high residual rate, poor pellet strength and low pellet iron grade existing in the process of producing iron ore pellets with bentonite and other binders. Results of examples show that green pellets have higher strength and shock temperature and the finished pellets have higher iron grade and excellent metallurgical properties, if the composite organic binder is used in an amount of 0.4-0.6% of the dry weight of iron ore concentrate.

Abstract: What is concerned is a power supply having a power status indicator, in which the power status indicator is powered by a constant voltage source, such as a constant voltage provided by an auxiliary power supply or a reference voltage provided for the internal control circuitry. Or otherwise, the power status indicator is connected in series with a feedback circuit or a protection circuit of the power supply, and the current-limiting resistor thereof is eliminated. In this way, the power consumption of the power supply under the standby mode is reduced, and the energy utilization of the power supply is enhanced.
