刚性的

The most interesting thing is that the space group of a non-chiral macrocycle was a chiral symmetry one. With a p-chlorophenyl substituent, the structure of the aromatice macrocyclic oligomer was unsymmetrical.

利用晶体结构参数计算出大环分子环状孔穴的有效直径，为这类刚性环状齐聚物作为一类纳米结构材料的应用作了理论上的准备。

An optimum combination of rigidity and lightweight engineering ensures the monocoque passenger cell of the original model is extremely strong while weighing an absolute minimum - it is a central element of the vehicle's structure.

一个最佳组合的刚性，重量轻工程确保了原模型单体乘客舱非常大，而体重降到最低-这是该车辆的结构的主要内容。
