Leaves simple, rarely trifoliolate, opposite, sessile or shortly petiolate, no more than 5 mm; blade ovate to oblong-ovate, 11-14(-16.5)× 5.5-7(-8) cm, coriaceous, glabrous, adaxially lustrous green, abaxially pale green, main vein impressed adaxially and prominent abaxially, lateral veins 5-9(-11) pairs, slightly discernible adaxially and conspicuous abaxially, base subcordate, rarely rounded, margin glandular crenate or -serrate, apex apiculate, cusp 5-10(-15) mm.

单叶，很少具三小叶，对生，无梗或短具叶柄，顶多5毫米；叶片卵形到长圆状卵形， 11-14(-16.5)* 5.5-7(-8)厘米，革质的，无毛，正面的是有光泽的绿色，背面的淡绿色，主脉正面凹陷和突出背面，侧脉5–9(–11)对，正面稍可见，背面明显，基部近心形，很少圆形，边缘腺状圆齿或腺锯齿，先端具细尖，尖突5–10(–15)毫米。

The simulation results show that the asymmetry structure of the ratchet die cavity influences the BMG's flowing behavior greatly. During the material filling tooth cavity, dead zone volumes exist and situate on the areas with sparse teeth distribution. The full filling or not of the ratchet tooth tips, as the final filling region of the forming process, determines the super-plastic forming quality. Adopting smaller punch speed or longer load holding time is necessary for full filling of the tooth tips.

研究结果表明，棘轮模腔结构的不对称性对材料的流动行为影响显著；在材料向齿形的充填过程中存在流动死区，死区的位置处于齿形分布较稀疏的部位；齿形尖角是成形的最后充填部位，在终成形阶段采用较小的压下速度或较长的保压时间，有利于齿形尖角的完全充满。

However, I m amazed at how often that doesn t happen, and I wind up landing the sharp-toothed fish on my fly rod.

不过，我小惊讶多久，又何妨笔发生，我总结登陆尖齿鱼，对我的鱼鳔。

Walking on all fours allowed animals to carry more weight, and size was often their only defense against sharp-toothed carnivores, said one of the report's co-authors, Matthew Bonnan of Western Illinois University.

该报告的共同作者西伊利诺大学马修巴南说，以四脚行走可让动物更可携重，而身体大小往往是它们对尖齿肉食动物唯一的防御。

From the simulations, we can see the distributions and transmission of strain and stress in model under different loadings, and the results explained the fractures very well. 4. Similarly, a axis FEM model was constructed to simulate the axis fracture, emphasized on the odontoid process. Three kind of odontoid process fracture were analysed on this model, which occurred respectively on the tip, the middle and the fundus. The results gave the best angle to fracture the odontoid process of the axis.

四、建立了枢椎的三维有限元模型，对枢椎齿状突骨折机理进行了理论上的研究，重点针对临床上齿突骨折的三种分类：1、齿突尖骨折；2、齿突腰部骨折；3、齿突基底部骨折，赋予齿状突在矢状面沿各种角度下受力条件，模拟衰椎前弓、襄椎横韧带以及CZ－3棘间韧带对枢椎造成的暴力破坏，确定了最可能引起齿状突暴力骨折的受力角度。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
