Abstract: Disclosed are a polyethylene glycol conjugate drug, and a preparation method therefor and the use thereof. Specifically, the present invention relates to a polyethylene glycol conjugate drug represented by formula A or a pharmaceutically acceptable salt thereof, a method for preparing the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof, an intermediate for preparing the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof, a pharmaceutical composition comprising the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof, and the use of the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof in the preparation of a drug.

Abstract: The present disclosure provides a parameter configuration device, including a first signal modulator, a second signal modulator and an operating member electrically connected with the first signal modulator or the second signal modulator. The first signal modulator and the second signal modulator have a connection state and a separated state. In the connection state, the first signal modulating element is electrically connected with the second signal modulating element, and the first signal modulating element and the second signal modulating element enclose a configuration space for a cable to pass through In the separated state, the first signal modulator is separated from the second signal modulator.

Abstract: A toaster has a housing has an operation cavity and a heating cavity. One side of the housing has a first opening, at least one second opening is disposed at the bottom of the housing, the operation cavity is connected to the heating cavity; a longitudinal groove with same number with the second opening, the longitudinal groove is disposed inside the housing, the longitudinal groove is extended upwards from the second opening; at least one transparent movable baffle, which is sliding and connected to the longitudinal groove from the bottom of the housing from down to up, part of the side surface of the movable baffle is exposed to the first opening; and at least one positioning mechanism, which is fastened to the housing and positioned or supported the movable baffle.

Abstract: A data retransmission method, apparatus, and system can improve a success ratio of data packet retransmission. A data retransmission method includes: after a source node continuously transmits at least two data packets to a destination node according to a go-back-N automatic repeat request, monitoring and decoding, by a relay node, the at least two data packets; storing a copy of a successfully decoded data packet; monitoring a response message to each data packet, where the response message is returned by the destination node to the source node; and sending a copy of a data packet that corresponds to a reception negative acknowledgment message to the destination node, when the monitored response message is the reception negative acknowledgment message.

Abstract: The present invention provides a processing method and processing device for automatically setting an Internet access mode. The method includes separately sending a PPPoE request message and a DHCP request message; if a DHCP response message corresponding to the DHCP request message is received first within a set time, determining that the Internet access mode is a DHCP mode; if a PPPoE response message corresponding to the PPPoE request message is received later within the set time, determining that the Internet access mode switches from the DHCP mode to a PPPoE mode. Embodiments of the present invention can improve accuracy of mode detection.

Abstract: The present invention is provided with a toaster, which comprising a housing, a longitudinal groove, a transparent movable baffle and a positioning mechanism. It can be observed from the exterior with the heating status of the toast, making it convenient to use. The movable baffle is sliding and connected to the longitudinal groove and positioned by the positioning mechanism, making it able to be drawn out of the housing to clean, so that the present invention is used with health, clean and it makes the food more delicious finally.

Abstract: A method for transferring test messages includes a Network Element (NE) A and NE B negotiating and determining a logical channel type. The Link Management Protocol (LMP) entity of NE A constructs a test message packet which includes the local Ethernet data interface ID, and transfers the test message packet to the local packet control module. The packet control module of NE A encapsulates the test message packet according to the logical channel type determined through negotiation, and transfers the encapsulated packet to the local transmitting interface. The receiving interface of NE B identifies and receives the packet. The packet control module of NE B obtains the packet from the local receiving interface and then encapsulates the packet. Next the packet control module of NE B transfers the test message packet obtained after decapsulation to the local LMP entity.
