Based on the combinatorial counting theory,the formulae of enumeration of such special binary cyclic sequences as self-mutual reverse sequences and self-complementary sequences,and that of primitive cyclic sequences after removing equivalent sequences are deduced so that the work of calculations can be reduced nearly four times.
以组合计数理论为基础,推导出特殊序列(自互反序列和自互补序列)计数公式和排除等价序列(互反、互补序列)后的本原周期序列计数公式,使搜寻可用序列的基序列数目约缩为原来的1/4。
补充资料:组合模式或组合振动
分子式:
CAS号:

性质:在红外光谱中通常出现很多的弱吸收,组合模式或组合振动系指对应于两个或多个基本振动频率之和起源,它的弱吸收于多原子分子振动态相互作用的振子的非谐性。与基频振动及倍频所引起的吸收相比,这些吸收是比较弱的。
