摘要:
The present invention discloses a method and device for reestablishment at packet data convergence protocol (PDCP) layer. On the receiving side of the PDCP layer, the method comprises: clearing resident control messages (501); processing resident service messages, and clearing feedback information generated during processing (502); and resetting a decompressor, and updating configuration of a decryption module (503). On the transmitting side of the PDCP layer, the method comprises: resetting a compressor, and updating configuration of an encryption module; clearing the resident control messages; and reprocessing the resident service messages. With the differentiated processing for the resident messages at the PDCP layer during the reestablishment, the present invention can avoid the abnormal mode switching of the compressor, and accelerate the user plane restoration after the reestablishment. The present invention can further avoid the transmission of invalid feedback, thus improving the utilization of air interface resources; meanwhile, by avoiding the influence of the invalid status report on uplink and downlink transmission policies, the present invention can reduce retransmission of the service messages, thus improving the utilization of air interface resources.

A method for improving the uniformity of high-frequency discharge plasma by means of frequency modulation is disclosed. In a plasma discharge chamber, there is a pair of parallel electrodes. A high-frequency power supply is adopted to feed the electrodes. The frequency range of the electromagnetic field is 13.56 MHz˜160 MHz. Discharge gas is input to form plasma. The frequency of the fed-in high-frequency electromagnetic field is under automatic tuning control, and keeps changing cyclically without stop in the course of plasma discharge. The range of the frequency change may fall into either a portion of or the entire range of 13.56 MHz˜160 MHz and makes the locations with higher plasma density on the plane in parallel with the electrodes and in the plasma discharge space changed cyclically. In a time slot longer than one frequency change cycle, the average plasma density between the parallel electrodes is uniform.

A conducting substrate made of a nickel coating on paper that can be used in a dye-sensitized solar cell (DSSC or DSC). Zinc oxide is the preferred wide-band semiconductor deposited as a nanoparticle layer on the nickel-coated paper to form a photoanode once a dye is deposited on the nanoparticles. A method of constructing the nickel-coated paper substrate is also contemplated.

摘要:
A damping device for a stay cable including a rotating lever, a lever support saddle, a longitudinal connecting member, and a rigid connection rod. When the stay cable vibrates inside or outside the plane thereof, the vibration displacement is transferred to the rotating lever through the rigid connection rod. One end of the rotating lever is connected to the lever support saddle via the longitudinal connecting member, and can rotate up and down with the lever support saddle as the axis and rotate around its central axis. The other end of the rotating lever is connected to a mass block and a damper. The damping device effectively inhibits vibrations inside and outside the stay cable plane, is easy to install and maintain, and does not negatively impact the appearance of a cable-stayed bridge.
