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。

本文研究中等和重质量核14MeV中子(n,t)反应截面的系统学特征,在考虑奇偶效应的基础上给出了系统学经验公式,计算结果和实验值符合较好,还讨论了Q值效应及可能的反应机制。
The value of the first-move advantage can be calculated after studying the even-odd effect in computer gaming programs.
还结合奇偶层效应对先行权作了量化,指出空着裁剪的本质同其他基于Alpha-Beta窗口的诸多裁剪算法是一致的,并阐述了诸多裁剪算法的作用被空着裁剪算法所掩盖的原因。
As an example, numerical fits to even-odd mass differences in the 154—171Yb isotopes shows that the new model is applicable to well-d.
