The most likely polymethylene bridge lengths within the pitch end-cut molecules were estimated from the CAMD results; a value in the range of C4 to C6 was most likely.The probability of C1 and C2 bridges was less because their total energies were comparatively high.

Athabasca沥青残渣组分中长度为C5到C7的桥链存在的可能性最大，而C1和C2桥链则由于其总能量相对较高，存在的可能性较小。

Based on the postulated 2D average molecular unit structures proposed by Zhao et al, 3D conformations for the end-cuts of Athabasca bitumen pitch in Canada were created using polymethylene bridges with different lengths by the Computer Aided Molecular Design method.

利用分子模拟技术对加拿大Athabasca油砂沥青超临界萃取分馏残渣组分的化学分子结构进行了研究，首先选用长度不同的桥链构建了其三维平均结构，然后采用分子力学和分子动力学方法得到能量最低也即最稳定的构象。

Objective: the pontic s with cavity were used in PFM bridges to avoid additional blebs.

目的：应用改良桥体结构的方法避免在铸造中产生的缩孔缺陷。

These bridges often use precast concrete beams.

这些桥梁经常使用预制混凝土射线。

Results It showed that the prolabium of complete BCL had no muscle, there were only weblike collagen fibers of bundles of them, capillaries, fats and fats and fiber－blasts. There were muscle fibers in prolabium and bridges of incomplete BCL,but ultra structure variations were found. The prolabium of complete BCL operated on with straight line suture method had muscle fibers proliferated from the lateral lips, but the fibers were sparse and also had ultra structure variations.

结果 发现完全性双侧唇裂的前唇部无肌纤维，双侧不完全性唇裂的前唇及桥部有少量肌纤维，但其超微结构有变异；用直线缝合法修复的完全性双侧唇裂的前唇部，有从侧唇增生的肌纤维，但稀少，超微结构亦有变异。

When the network topology changes, switches and bridges recompute the spanning-tree and cause a disruption in network traffic.

当网路拓扑改变，交换器与桥接器会重新计算扩充树，此时会导致网路流量的中断。

However, the safety of the long-span bridges is increasingly prominent because of the reciprocity of wind, vehicle, temperature and seism.

悬索桥是应用于大跨桥梁的一种新型结构型式，具有跨度大、造型优美和节省材料的优点。

With the development of technology and transportation enterprise, the continuous rigid frame bridges develop rapidly and grow towards long span and more flexibility. It makes the analysis of the stability, temperature and seism more important.

近年来，随着科学技术和交通事业的发展，连续刚构桥也因此被广泛应用而发展起来，并逐步向大跨、轻柔方向发展，这样使得结构的稳定问题、温度问题、抗震问题日益突出。
