反式构型（ transconfigurationpolymer），是分子以反式构型为主的聚合物，主要作用是替代石膏用于固定骨折。
计算结果表明，NMF的顺式和反式构型都可以与水分子形成线型的氢键结构。
The results show that both cis - and trans - form of NMF can form a linear hydrogen bond with water.
结果表明，在不同基组水平上，由MP2，QCISD，B3LYP方法均能得到草酰碘分子的交叉式构型和平面反式构型，与实验所得草酰卤化物的构型完全相符。
The result shows that MP2, QCISD, B3LYP can gain the gauche and anti conformers of oxalyl iodide, which is in good agreement with configuration of oxalyl halides in experiment.
这是因为，按照线性拟合外推的结果仅仅适用于线型构型（均为反式）的碳链。
This is because the linear extrapolation only holds for a chain that adopts a linear (all-trans) configuration.
