The X-ray coaxial phase-contrast imaging method disclosed by the invention can be used for effectively increasing the contrast of a phase-contrast image under a deterioration effect and guaranteeing the fidelity of a recovered image.

The invention discloses a flocking embroidery process. The flocking embroidery process comprises the following steps: (1) pattern drawing; (2) base cloth setting; (3) primary pattern embroidering; (4) flocking treatment on patterns; (5) secondary pattern embroidering, namely embroidering all of the patterns by use of mutual match of long, short, sparse and dense stitches, and enabling the stitches to pass through the flocked surface; (6) flock fixing treatment, thus completing the embroidering of the patterns. In the way, the flocking embroidery process creates a pioneer of adding flock to embroidered clothing, and as a result, the reality and the beauty of the embroidered patterns, particularly animal patterns or some flower patterns, are guaranteed, and the obtained embroidery is high in third dimension and lifelike.

The invention provides a method and device for adjusting a video playing interface. The method and device are used for a smart television. The method includes the steps of obtaining a target network video according to a received actual playing address of the target network video, and stretching an obtained display scale of the target network video according to a preset screen ratio of the smart television so that the target network video can be played at the preset screen ratio. According to the method, after the target network video is selected, when the target network video is played, the target network video is automatically stretched and played according to the screen ratio of the smart television, the vividness of images is guaranteed, a user does not need to operate manually, operations are simple and user experience is improved.

A nanoimprint method is provided. A substrate and a master stamp are first provided. The substrate has a first resist layer, a transition layer, and a second resist layer orderly formed thereon. The master stamp has a nanopattern defined therein. The second resist layer is a layer of hydrogen silsesquioxane. The nanopattern of the master stamp is then pressed into the second resist layer to form a nanopattern in the second resist layer at normal temperature which is in a range from about 20 centidegrees to about 50 centidegrees. Finally, the nanopattern of the second resist layer is transferred to the substrate.
