Leaves opposite; petiole 4-7 mm; leaf blade elliptic to obovate, 3-8 × 1-4 cm, leathery, pubescent when young but glabrescent and shiny with age, abaxially gray tomentose, secondary veins 1 on each side of midvein, originating near leaf blade base, and meeting at apex, tertiary veins 4-6 on each side of midvein and connecting midvein to secondary veins, reticulate veins obvious, intramarginal veins 3-4 mm from margin, base broadly cuneate, apex rounded to obtuse and often slightly emarginate or sometimes slightly apiculate.

叶对生 叶柄4-7毫米；叶片椭圆形到倒卵形， 3-8 * 1-4 厘米，革质，幼时具短柔毛但老时脱落无毛和发亮的，背面灰色被绒毛，次脉在中脉两边各1，近叶片基部发出，在先端会集，第三脉在中脉两边各4-6和连结中脉和次脉，网脉明显，近边缘内脉距边缘3-4毫米，基部宽楔形，先端圆形到钝和通常稍微凹或有时稍具细尖。

The present author attempts to explore the nature of the mystery elements in his work by studying his masterpieces, The Scarlet Letter, The House of Seven Gables, and The Blithedale Romance, and other stories,"Young Goodman Brown","Roger Malvin's Burial", and "The Hollow of the Three Hills" etc.

通过分析霍桑的三部长篇小说《红字》、《有七个尖角阁的房子》、《福谷传奇》，以及短篇小说《好小伙布朗》、《胎记》、《罗杰·马尔文的葬礼》、《三丘之谷》等作品中的神秘因素，本文主要揭示了神秘因素的用途。

Trituberculatus, China's coastal areas are production, back on both sides have developed a sharp protrusion, fifth right pereiopod bian wide, suitable for swimming.

三疣梭子蟹，中国沿海均产，背甲两侧有发达的尖突，第五对步足扁宽，适于游泳。

Sea dragons, seahorses and pipefish are the only species where the male carries the eggs, Gladish said.

他说，海龙，海马，还有尖嘴鱼是仅有的三种由父亲来孕育后代的物种。

Premolar is short, simple structure in front of three, single-pointed.

前臼齿短，前面的三个构造简单，单尖。

The apex of the third molar root is mea-sured 11.3mm to the medial alveolarridge.

第三磨牙根尖至内侧牙槽嵴的距离为11.3mm。

In this paper,the comparative studies on the effects of triazine herbicide Atrazine on seedlings growth,contents of chlorophyll and soluble protein,chromosome structure of root meristem,protein compositions of root meristems and chloroplast have been made in Oryza sativa.

比较研究了不同浓度三氮苯类除草剂对水稻幼苗生长、叶绿素及可溶性蛋白质含量、根尖分生组织染色体结构、分生组织和叶绿体蛋白质组分的影响。

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。
