1) perfect nematic order
理想向列序
1.
The perfect nematic order is assumed in the theoretical treatment, that means the orientation of the molecular long axis coincides with the director of liquid crystal and the total free energy equals to the total interaction energy.
理论处理中假定具有理想向列序,这意味着分子长轴取向方向与液晶指向矢是重合的,而总自由能等于总相互作用能。

2) ideal principal series
理想主序列
3) best environmental sequence
理想环境序列
1.
A new environmental impact assessment(EIA) method-the grey relational analysis for the overale EIA is presented based on the thought using the grey relational grades of the environmental sequences without project and with project to the best environmental sequences as indices to judge project's impact on total environmental factors.
如何确定理想环境序列是该方法的关键。
