    摘要： Block copolymers containing block having pendant fluoro-containing groups and block having pendant hydrolyzable ester containing groups is developed at lower pressures and temperatures than random copolymers of the same monomers. Where the block with ester groups is from polymerization of 2-tetrahydropyranyl methacrylate and the block with pendant fluoro-containing groups is from polymerization of perfluoroalkyl methacrylate or semifluorinated alkyl methacrylate, resolution of sub 0.3 &mgr;m features is enabled.

    摘要： The adjustable clothes hanger includes a main frame. Shoulder sliders are movably disposed at two ends of the main frame, and sliding racks of which one ends extend inside the main frame are disposed inside the shoulder sliders. Driving gears that engage with the two sliding racks are movably disposed inside the main frame. An upper hook of which one end extends inside the driving gears is disposed at a top of the main frame. The two shoulder sliders may be synchronously driven by pressing the upper hook downwards and rotating the upper hook, so that widths of a right end and a left end of the main frame are the same. The clothes can be adjusted based on an actual width of the clothes. Therefore, the clothes are not bulged and deformed. The upper hook may be reset through the spring when not used, to maintain the upper hook in a normal freely-rotating state.

    摘要： In the field of communication technologies, a method and an apparatus for acquiring a Precoding Matrix Indicator (PMI) and a Precoding Matrix (PM) are provided. The method includes: acquiring a reference PMI and a differential PMI according to a first non-differential codebook and a first diagonal differential codebook, where codewords included in the first diagonal differential codebook form a diagonal matrix. The apparatus includes a PMI acquiring module. Acquiring a reference PMI and a differential PMI according to a non-differential codebook and a diagonal differential codebook can reduce the feedback overhead or improve the feedback precision; and the fact that codewords included in the diagonal differential codebook form a diagonal matrix can maintain amplitude characteristics (for example, a constant modulus characteristic, and a finite character set constraint characteristic) of elements of the non-differential codebook or facilitate power distribution among antennas.
