摘要
将ＤａｖｙｄｏｖＦｉｌｉｐｐｏｖ的非轴对称转子模型推广到超形变核态，给出了一个新的超形变带的转动谱公式；并应用该公式，确定了１９０区偶Ａ核超形变带的带首自旋；将轴对称四极形变β和非轴对称度γ参数与正常形变带作了比较．结果表明：前者比正常形变核态大得多，而γ形变虽然普遍较小。
Synthesis and analysis filters in DWMT system are investigated. Based on the requirements of computational complexity and subchannels spectral separation properties in DWMT system, ELT fast algorithm is used. And in filter optimization procedure, the minimum peak error criteria are employed instead of the minimum stopband energy criteria originally used in ELT algorithm.
