    摘要： The present invention provides a method and apparatus for determining a transmission power of a secondary transmitter in a hierarchical spectrum sharing system. The method can comprise steps of obtaining channel quality information on a primary link from at least one primary receiver within a transmission range of the secondary transmitter; and determining the transmission power for the secondary transmitter based on the channel quality information, wherein the transmission power is matched with the channel quality indicated by the channel quality information. According to the embodiments of the present invention, a power control scheme is applied to the secondary transmitter based on the channel quality information on the primary link. In such a way, the secondary transmitter' throughput can be improved with controllable rate loss to the primary receiver and accordingly the spectrum efficiency for the whole system can be further upgraded.

    摘要： The present invention belongs to the field of surface modification of solid materials, specifically relates to a method of changing the surface wettability of polymer materials. The method of the present invention comprises of rubbing the surface of the polymer materials various times by using sand paper of different grades (GB/T 15305) with a determined pressure at the ambient temperature, so as to change the contact angle of said surface of polymer material with water thereby changing the surface wettability of the polymer materials to different degrees. The method of the present invention has advantages of using devices that are simple, low cost, and the surface characteristics of the polymer materials could be changed from hydrophilicity to hydrophobicity, from hydrophobicity to super hydrophobicity, or from hydrophilicity to super hydrophilicity, at ambient temperature without any special requirement to the polymer materials or the preparation process thereof.
