梁

Gary Packard of Colorado State University and his colleagues do not deny that creatures like Apatosaurus, Brachiosaurus and Diplodocus were big—and bigger than any terrestrial mammal.

来自科罗拉多州立大学的Gary Packard及其同事并不否认一些动物如虚幻龙、腕龙、梁龙很大——比任何陆地上的哺乳类动物都要大。

A complete and beautifully preserved saurischian hip girdle was the most stunning, but many other sauropod bones were collected, including sections of backbones from an Apatosaurus and a Camarasaurus.

在以前发现剑龙、跃龙，鸟脚类和其它梁龙类的遗址上，采集到了一个令人十分欣喜的、保存极其完好的蜥臀类腰带。

Apatosaurus（Saurischia,Sauropoda,Diplodocimorpha）,Late Jurassic,up to 26m

雷龙（蜥臀目，蜥脚类，梁龙形类），侏罗纪晚期，体长最长可达26米。

New bone formation was observed to be increasing significamly in both DCN bone cements and DC bone cements with the passage of time. By the end of 24 weeks, new bone had bridged the gap between the proximal and distal fragments in DCN bone cements and DC bone cements. By histomorphological detection in DCN bone cements, Abundant of chondral and new bone islands were seen at the site of defects 4 weeks after the operation and a number of new bones formed and enlarged by both enchondral ossification and appositional formation by the 8th weeks.

研究发现，DCN骨水泥植入4周大量间充质细胞分化，在材料与骨端之间出现一层软骨细胞，软骨细胞继续增生并向编织骨分化；8周材料降解的同时，小梁骨出现；12周新骨长入材料并已经基本替代完成，形成初步骨性连接；24周骨缺损完成骨性连接，新骨进行结构改建，材料内部形态结构明显变化。

Many methods on calculation of deflection of prestressed concrete beams have been proposed both at home and abroad, most of which were empirical formulas for approximate engineering calculation.

有关预应力混凝土梁的挠度计算，国内外学者提出了不少计算方法，但几乎都是以满足工程要求为前提的近似经验公式。
