Fingerprint image watermarking algorithm using the quantization of parity based on Contourlet transform;
基于奇偶量化的Contourlet变换域指纹图像水印算法
A related method for stereo center classification, recognition and parity calculation from structure diagram was developed, and expanded to atropisomers and dummy axial stereo centers.
利用奇偶值在计算机中对立体化学进行表征可以避免复杂的CIP规则。
The difference to achieve parity ending among sense groups has three forms,with the first one ending by pure even or uneven sentence,the second one ending by the resumption between even and uneven sentence and the last one ending by independent sense group called Ao Style.
意群间以收句奇偶的不同呈现三种形式:一为纯奇纯偶收结;一为奇偶交错收结;一为独立意群示拗收结。
The result shows that molecules with non-alkyloxy substituent are nematogenic and short alkyloxy chains (n= 1～3 ) in the homologue lead to nematic phase with odd-even effect, the molecules with longer alkyloxy chains (n=4～1.
当Y为非烷氧基时,呈向列相液晶;当Y为较短的烷氧基时(n=1～3),液晶化合物具有向列相(N);Y为较长烷氧基时(n=4～16),液晶化合物只有近晶B相(SB)和近晶A相(SA);SA-I相变的熵变随烷氧链原子数而奇-偶变化,但与N-I相变的“奇-偶效应”相反。
