方法采用二次抛物拱的原理来分析和计算足部纵弓的受力状态。
However, it is restricted in application owing to the lack of a sound theory about the calculation of force of the parabolic oblique arch bridge.
但对抛物线斜板拱桥的受力计算尚无成熟理论，使之应用受到限制。
We have argued that Asian conversations show a pattern which can be described as a parabolic arch, beginning with incidental topics and minor points. The main topic is introduced somewhat later.
亚洲人的谈话方式可以描述为一个拱形，开始的时候谈论一些比较随意的话题，然后再引入主题。
