Abstract: A powertrain including an integrated housing, a motor, and a motor controller. The integrated housing includes a motor accommodating cavity, a controller accommodating cavity, a direct-current input interface mounting hole, and an alternating-current output interface mounting hole. The motor includes a motor shaft and a motor winding. The alternating-current output interface mounting hole and a wiring terminal of a winding of the motor are arranged on one side along a first direction. The direct-current input interface mounting hole and an output end of a shaft of the motor are arranged on the other side along the first direction. A projection of the direct-current input interface mounting hole, a projection of the alternating-current output interface mounting hole, and a projection of the motor shaft do not overlap along a third direction. The powertrain in this application has a compact layout to implement miniaturization.

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: A screen component includes a screen body and at least one vibration assembly. The vibration assembly includes a movable member made from a giant magnetostrictive material and at least one coil surrounding the movable member, and the movable member is partially attached to the screen body. The at least one coil forms a magnetic field when the coil is supplied with an input current. The movable member deforms under the effect of the magnetic field. The magnetic field changes according to a change in parameter of the input current. A deformation amount of the movable member changes according to the change in magnetic field of the coil to drive the screen body to vibrate to output corresponding sound information by the screen component.
