  • Publication number: 20200140761
    Abstract: A triphase organic matter pyrolysis system includes multiple devices cooperating with each other. The feeding device delivers organic matters into the preheating device. The preheated organic matters are delivered into the pyrolysis and carbonization reaction device. The steam generating device produces a saturated steam which is delivered into the water ion generating device which heats the saturated steam into a superheated steam which is dissociated into water ions which are delivered into the pyrolysis and carbonization reaction device. The water ions cut, dissociates and carbonizes the organic matters to form carbon residues and gas-liquid wastes. The heat energy is recycled by the heat recycle device and is delivered into the preheating device. The gas-liquid wastes are processed by the gas-liquid separation device and the gas purifying device to form gas and liquid that are harmless.

  • Patent number: 10601554
    Abstract: The present invention discloses a packet transmission method and user equipment. The method includes: transmitting, by a sending node, multiple packets to a receiving node; receiving multiple acknowledgement packets from the receiving node; after determining, based on the received multiple acknowledgement packets, that a first packet is lost, retransmitting the first packet; and if it is detected that the retransmitted packet is lost, continuously retransmitting, by the sending node, the first packet to the receiving node in a preset time interval for at least twice. According to the solutions of the present invention, the retransmitted packet can be detected and recovered in time after the retransmitted packet is lost, thereby reducing a quantity of times of timeout retransmission, improving a transmission rate, moreover, reducing a packet loss probability of a retransmitted packet, and further reducing a probability of timeout retransmission.

  • Publication number: 20200029243
    Abstract: This application discloses a method and an apparatus for adjusting a data sending rate. In the method, when determining that a return time of feedback information of a first data packet has timed out, a terminal reduces a data sending rate of a connection to which the first data packet belongs from a first value to a second value. Then the terminal detects return times of feedback information of a plurality of subsequent data packets after the first data packet and determines a cause of the timeout of the feedback information of the first data packet. The terminal further increases a data sending rate from a current third value to a fourth value when determining that the timeout is caused by a packet loss on a wireless link in a communications link.

  • Publication number: 20190319889
    Abstract: A packet transmission method and related apparatus are disclosed. A transmit end retransmits a first packet to a receive end and decreases a congestion window and a slow start threshold upon determining that the first packet has been lost. The receive end sends an ACK in response to the retransmitted first packet to the transmit end on receipt of the retransmitted first packet for the first time, where the ACK contains a proactively constructed DSACK option for informing the transmit end that the first packet has been received repeatedly. The transmit end therefore compensates the congestion window and/or the slow start threshold.
