Embodiments of this application provide a middle frame, a battery cover, and an electronic device. The electronic device may include a mobile or fixed terminal with an edge frame or a housing, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a POS machine, a personal digital assistant (PDA), an event data recorder, a wearable device, a virtual reality device, a wireless USB flash drive, a Bluetooth speaker/headset, or a vehicle-mounted device. Two types of materials: ceramics and plastic, are used to form a middle frame and a battery cover, thereby reducing a weight of the electronic device. This resolves a problem that is of a relatively large weight of an existing electronic device and that is caused when a pure ceramic middle frame and a pure ceramic battery cover are used in the electronic device.

Middle frame, battery cover, and electronic device

Disclosed are a pentacyclic triterpene compound as shown in general formula (I) and a preparation method therefor. The compound has an effective antagonistic effect on FXR receptors. 

Pentacyclic triterpene compound and preparation method therefor, and pharmaceutical composition and use thereof

A system for multi-chassis interconnection and a method for chassis connection are disclosed. The system includes at least three chassis; each chassis includes a first switch fabric unit (SFU) and a second SFU; the first SFU in the first chassis is connected to the first SFU in other chassis; and the second SFU in the second chassis is connected to the second SFU in other chassis. In the embodiments of the present invention, different SFUs in the chassis of the multi-chassis interconnection system are connected to different main chassis, thus overcoming the technical defect in the prior art that other chassis in the multi-chassis interconnection system are unable to exchange data when the main chassis is faulty. Therefore, in the embodiments of the present invention, other chassis in the multi-chassis interconnection system can still exchange data normally when the main chassis is faulty.
