The invention discloses LncRNA related to chicken residual feed intake or heterosis, a target gene regulated and controlled by the LncRNA and application of the LncRNA. Data analysis shows that the residual feed intake and heterosis of the chickens are remarkably related to the oxidative phosphorylation process; a non-additive expression gene LncRNA and a target gene COX5B are further analyzed and screened through a weighted co-expression network and are highly related to the residual feed intake character and the heterosis of the residual feed intake character, and an analysis result is verified by detecting the ATP content; besides, by detecting the content of liver tissues of individuals of the next generation of a sequencing group, it is found that the LncRNA, the COX5B and the LncRNA are remarkably related and are all remarkably related to the residual feed intake of the chicken, and therefore it is determined that the LncRNA and the COX5B affect ATP generation of the body by participating ...

Multi-range processing type deburring device for motor magnet ring processing

Номер: CN116460684A
Автор: SUN YANYAN
Принадлежит:

The invention discloses a multi-range processing type deburring device for motor magnet ring processing, which comprises a bottom plate, a support frame is fixedly mounted at the top of the bottom plate, a moving device is arranged in the support frame, a clamping device is arranged between a right support plate and a left support plate, and the clamping device comprises a rotating unit and a clamping unit. The clamping unit is arranged on the inner side of the rotating unit. According to the multi-range machining type deburring device for motor magnet ring machining, a handle is rotated to drive a rotating rod to rotate, and the rotating rod drives a gear to rotate while rotating, so that the gear is engaged with a rack at the bottom of a connecting piece, and the connecting piece moves left and right along a fixing rod; by controlling the rotating direction of the handle, the connecting piece moves back and forth to grind the machined workpiece for multiple times, so that the deburring ...
