As a result of analysis to many of the results of experiment, checked up on specimens, field investigation and combining with the theories of palaeobotany, comparative morphology, evolutional morphology of vascular plants and taxonomy, it can be concluded as following: the primitive sorts of Cycadaceae are the sorts that pinnate leafs are dichotomy; among these, the sort that pinnate leafs are tripinnate-dichotomy is most primitive, from this sort gradually evolve to bipinnate-dichotomy, to only for monopinnate-dichotomy, from this sort evolve to the sorts that pinnate leafs are simply pinna; among the sorts of simply pinna, the species that segments of megasporophyll possess much more triplicate to monodichotomy are most primitive.

经过大量的实验结果分析、查阅标本和野外调查，结合古植物学、比较形态学、演化植物学和分类学等理论进行分析，认为苏铁科原始的类型为羽叶呈二歧状分叉的种类，其中最原始的又是羽叶呈三回二歧状分叉的种类，从这个羽叶类型逐渐演化出一回二歧状分叉的羽叶类型，再演化出羽叶为单羽状的类型；而单羽状叶的类群中，又以大孢子叶侧裂片具三回、二回及一回二歧状分叉数量多的种类为最原始，而侧裂片二歧状分叉数量少的为较进化，侧裂片无二歧分叉的如拳叶苏铁类为最进化的种类。

objective study on the nature of medicine and biology of medpor plasty plate,and its clinical results and pinna support in reconsurction of auricleⅰstage.methods 25cases with congenital absense of auricle were operated useing medpor plasty pinna support.results twelve five cases were successfcelly.the pinna support were easy to process,not easy to be out of shape,no toxin,and its histocomitibility was good.conclusion it is sugˉgested that using medpor plasty to be pinna support iyas good for reconstruction of auricle.

目的 探讨使用一种新材料medpor支架医学生物学性能及其在耳廓再造术中的临床应用效果。方法 25例先天性小耳廓畸形采用medpor为支架行ⅰ期耳廓再造术。结果25例耳廓再造皆成功，耳廓支架易加工，不易变形，无毒，与组织相容性良好。结论采用medpor材料作为耳廓再造的支架是可行的新材料。它无须切取自体肋软骨之苦，既能缩短手术时间，立体感又强，微细结构清晰。

There were six themes in this study. First of all, the geometry of in-vivo human pinna and ear canal was measured non-invasively. The 3D model of pinna and ear canal was reconstructed and then measured based on the image processed by HRCT. Second, the 2D curvature of in-vivo human ear canal was measured non-invasively. The angles and curvatures of superior and inferior walls of first and second bends were measured. The 2D curvature of ear canal was computed by sine and cosine laws. Third, the in-vivo human ear canal was reconstructed by RE. The distribution of sound field was analyzed by FEM. The data obtained in this study can be the reference for clinicians and audiologists. Fourth, the 3D model of earmold of hearing aids, including the ear shell and the housing, was reconstructed by RE based on the image of in-vivo human ear canal obtained by CT.

本研究主题其四，对於听力受损之患者往往皆须选配助听器帮助其放大声音，其中耳模是助听器的外壳，也是接触到耳朵的仪器，而耳道型助听器系位於耳甲艇及耳甲腔延伸至耳道第一弯道处，在制作耳模必须利用灌模方式来取得紧配之耳模，其中耳模在助听器的使用过程中，常因耳模松脱，无法与人耳道紧密配合而造成漏音，因此，利用活体人外耳道电脑断层影像，重建耳道型助听器耳模之三维立体模型影像，其中耳模包括了耳壳及耳模内部空间，并进行几何外型量测，探讨耳道型助听器之体容积大小，也提供了制作耳模时快速、精确度高、减少翻模及修模次数，可减少误差率之方法。

The two species are similar in stomatal character and in the absence of accessory transfusion tissue, but they are very different in stomatal distribution, pinna venation pattern and pinna marginal shape, presence or absence of mucilage canal, differentiation of palisade and spongy parenchyma, characteristics of girder parenchyma and epidermal anticlinal wall.
