Abstract: The present disclosure discloses an atmospheric-pressure plasma equipment for fabric functional finishing and its application, and belongs to the field of textile printing and dyeing engineering. The atmospheric-pressure plasma equipment, including a discharging system, a grafting instrument and a cloth guider, can conduct continuous plasma treatment on fabrics under an atmospheric pressure, including plasma etching and plasma grafting, which breaks through the disadvantage of batch processing of vacuum plasma equipment. The equipment and method of the present disclosure realize functional finishing of the fabrics in the absence of water, and this finishing process is cost efficient, environmentally friendly, uniform, shorter treatment time and higher reactivity, and applicable to many materials and can keep the bulk properties of the treated substances.

Abstract: The present invention provides a method for preparing a microgroove array surface with a nearly cylindrical surface based on an air molding method, and relates to the technical field of functional surface preparation. The method includes the following steps: (1) preparing a microgroove array surface, uniformly spreading a layer of a liquid polymer film to be formed on the auxiliary plate, and placing a spacer block in an empty position on the microgroove array surface; (2) placing the auxiliary plate spread with the liquid polymer film on the spacer block on the microgroove array surface, maintaining this state, and feeding the auxiliary plate into a vacuum drying oven; and (3), setting a pressure in the vacuum drying oven according to a designed pressure, heating and solidifying the liquid polymer film, and separating the microgroove array surface to obtain the microgroove array surface with the nearly cylindrical surface.

Abstract: It has now been found that in some transmitter implementations which transmit multiple code channels, for example CDMA transmitters, the observed power for each code channel at the output relative to the other code channels is dependent upon the total transmit power due to non-linearities in the transmitter. Methods and apparatus are provided which use pre-set digital gains or digital gain adjustments to compensate for the non-linearities as a function of total transmit power such that at the output, the desired relative powers are observed.
