In addition , parameterized design of involute columnar vertical gear ' s 2 - d part drawing and calculating the basic parameter of gears outer - mesh are available in this software 此外，该软件还实现了渐开线圆柱直齿轮二维零件图的参数化设计，并能够计算外啮合齿轮的基本参数。
At low magnification , one can see the pointed or blunt finger - like papillary projections lined by pseudostratified columnar epithelium and enclosing delicate fibroascular stroma 低倍镜下，可见其表面呈绒毛状或细乳头状突起。肿瘤表面覆盖一层假复层柱状上皮，包绕着纤维血管基质。
Detail of simple columnar epithelium with striated border ( microvilli ) . notice that the border is quite thin and the striations close together , looking like very regular , closely set brush bristles 单柱上皮表面纹状缘（微绒毛） 。注意：纹状缘很薄、排列规则精密，状如鞋刷的毛簇
The round columnar joints show that the dyke swarms are in upper crust brittle tectonic setting , and the western shandong block is brittle extensional in the mesoproterozoic time 岩墙发育圆柱状节理表明岩墙侵位时地块已经处于上地壳脆性构造环境,中元古代鲁西地区是一个脆性伸展的大地构造环境。
These all show pronounced stratification . there are three kinds of neurons related to the optic lobes : amacrine cells , columnar neurons and tangential neurons , only a few of which are stained 视叶包含三种神经元：无长突神经元、柱状神经元和切向神经元，其中只有少数被标记，与前脑间的神经通路呈弱阳性反应。
This is chronic cervicitis at the squamo - columnar junction of the cervix . small round dark lymphocytes are seen in the submucosa , and there is also hemorrhage . chronic cervicitis is quite common 图示宫颈柱状上皮、鳞状上皮交界处的慢性子宫颈炎，粘膜下层可见小而圆且染色深的淋巴细胞，以及出血。慢性宫颈炎是常见病变
The round columnar joints are one of the flow structures showing the horozontal emplacement of basic dyke swarms . the round columnar joints show that the basic dyke has rheological behaviour of the viscous shearing in magma emplacement 岩墙发育圆柱状节理表明出露的是岩墙的顶部，反映基性岩墙群侵位时岩浆具有黏滞性剪切作用的流变学特征。
The results showed that the lumen of small intestine was lined by the simple columnar epithelium , most of the cells were high columnar absorbing ones with abundant developed microvilli 结果表明，中华鳖小肠黏膜上皮为单层柱状上皮，以高柱状吸收细胞为主，具有发达的微绒毛、线粒体、粗面内质网和膜包小囊泡，其结构的发达程度已接近高等哺乳动物和鸟类。
