Abstract: Embodiments of this application provide a heating control method and apparatus, an oil pump, and a heat exchange system. The method includes: in a cold state, injecting a heating current into an oil pump motor, where when the oil pump motor is not started, a torque that the heating current is capable of generating is zero, and after the oil pump motor is started, heating power of the heating current is greater than heating power of an energy-saving current, where the energy-saving current is a current capable of enabling a first motor to reach a target operating condition when oil temperature is greater than a preset temperature threshold.

Abstract: The present invention relates to a molecular marker, a specific primer pair, and an identification method of the high-quality Ganoderma lucidum strain HMGIM-M624. The high-quality Ganoderma lucidum strain HMGIM-M624 was preserved in Guangdong Microbial Culture Collection Center (address: 5th Floor, No. 59 Building of No. 100 Yard, Mid. Xianlie Road, Guangzhou City) with the preservation number of GDMCC No: 60889 on Nov. 7, 2019. The molecular marker is an InDel molecular marker. The high-quality Ganoderma lucidum strain HMGIM-M624 has a base deletion of CATGCTGTA at the 246451th-246460th site of the chromosome sca34. The present invention provides reagents for detecting the molecular marker of the high-quality Ganoderma lucidum strain HMGIM-M624. The reagents can distinguish the high-quality Ganoderma lucidum strain HMGIM-M624 from the other 11 G. lucidum strains for commercial cultivation, thus specifically identifying the high-quality Ganoderma lucidum strain HMGIM-M624.

Abstract: An antioxidant for use in treatment for a radiation-induced bystander effect to a transplanted cell in a host is provided. The antioxidant is N-acetyl-L-cysteine, sulforaphane or resveratrol, or a combination thereof. The RIBE on transplanted human hematopoietic cells impaired the long-term hematopoietic reconstitution of human HSCs as well as the colony-forming ability of HPCs, and the RIBE-affected human hematopoietic cells showed enhanced DNA damage responses, cell cycle arrest and p53-dependent apoptosis, mainly due to oxidative stress. Taken together, these findings suggest that RIBE impairs human HSCs by oxidative DNA damage. The present disclosure provides definitive evidence for RIBE in transplanted human HSCs and further justifies the necessity for conducting clinical trials to assess the ability of multiple antioxidants to improve the efficacy of HSC transplantation for patients with hematological or non-hematological disorders.

Abstract: A power supply circuit includes a first input end (IN1), a second input end (IN2), a first output end (OUT1), and a second output end (OUT2). An input end of a first voltage conversion circuit (VCC) is used as IN1 and connected to an output end of a solar panel. A first output end of the first VCC is used as OUT1 and connected to a first power supply end of a monitoring chip. A second output end of the first VCC is connected to an input end of an energy storage module. An input end of the rectifier circuit is used as IN2 and connected to an AC power network. An output end of the rectifier circuit is connected to an input end of a second VCC. An output end of the second VCC and an output end of the energy storage module are used as OUT2 and connected to a second power supply end of the monitoring chip.

Abstract: An insulation resistance detection circuit and method are disclosed. The circuit includes a controller configured to: open a first relay, and close second relays, or switch an on/off status of at least one of the second relays; determine, based on a first measurement value between a positive input terminal of an inverter circuit and an earthing point, whether the positive input terminal of the inverter circuit is short-circuited or has low resistance to protective earthing; and determine, based on a second measurement value between a negative input terminal of the inverter circuit and the earthing point, whether the negative input terminal of the inverter circuit is short-circuited or has low resistance to protective earthing, where the first relay is one of in M relays and is connected to at least one impedor in parallel, and the second relays are relays other than the first relay in the M relays.

Abstract: A heating apparatus includes: a motor control unit, having an inverter and a controller that are connected to each other; an electric heater; and a motor, having three-phase windings, where ends of the three-phase windings are connected to the inverter, the other ends of the three-phase windings are connected to a connection point, and the connection point is connected to the electric heater. Therefore, the electric heater can be controlled by using the motor control unit that controls the motor, without a need to independently dispose a control circuit for controlling the electric heater, so that a quantity of controllers, a weight of the heating apparatus, a required occupation space of the heating apparatus, and costs of the heating apparatus can be reduced.

Abstract: Disclosed is a washing machine. The washing machine comprises an impeller, a decelerating clutch and an impeller connection assembly, wherein the decelerating clutch has a rotary shaft; and the impeller connection assembly is clamped and clamped and fixedly connected to the rotary shaft, so that the impeller is clamped and fixedly connected to the rotary shaft in a detachable way, thereby reducing the difficulties of the assembly and disassembly of the impeller, and prolonging the service life of the washing machine.

Abstract: Provided are a washing machine and a washing drum thereof. The washing drum comprises a large container and a small container. The small container is detachably disposed in the large container, and an opening of the small container and an opening of the large container are positioned opposite to each other. In a washing process, clothes needing special care can be placed in the small container so that water in the large container does not enter the small container, thereby realizing separating washing of the clothes needing special care. If there are no clothes needing special care, the small container can be detached from the large container to perform a normal washing operation.
