The mechanical property testing shows that the seamless PLLA tubes perform excellent radial strength,which indicates that the mechanical properties of biodegradable stents made of these tubes was supposed to be excellent.PLLA and its composites were first used in preparing seamless tubes as antecedency of laser-cut biodegradable coronary stents in china.Finite element analyses of the biodegradable coronary stent model indicate the explorative design basically meets the requirement of reasonable and applicable stents.There is not such kind of research yet in domestic.Optimum laser-cuttting parameters of CO2 laser was cauculated based on experiential formula,within it,biodegradable coronary stents,especially those with complex structure would be manufacutured from seamless tubes quickly by laser microprocessing with high consistency to the design model.The processing efficiency of the CO2 laser demonstrated in experiential formula by us will play an important guiding role in manufacturing biodegradable stents by laser-processing.Our stents that ascribed to laser-cutted,slotted tube stent are proved to be biodegradable, self-expandable and good biocompatible,basically reach the international level on the aspest of manufacturing procedures and design.

研究结果表明：壳聚糖改性材料综合性能优于纯PLLA，更适合于作为可降解冠脉支架的原材料；自主设计的探索性自膨胀管状闭环型可降解冠脉支架的性能符合冠脉设计要求，设计、验证生物可降解冠脉支架模型的研究在国内还未见报道；制备的改性PLLA无缝管的力学性能优越，可通过激光切割获得冠脉支架，这是国内首次采用聚乳酸材料来制备通过激光加工出可降解冠脉支架的无缝管；二氧化碳激光器加工精度能达到加工要求，加工出来的血管支架名义设计与实测值误差小，实现了冠脉支架、尤其是带有复杂外观设计冠脉支架的快速化、规范化加工，对二氧化碳激光器加工聚乳酸材料的效果研究在国内外属于首创，获得的经验公式对日后的深入研究有重要的指导意义；制备的支架为激光切割管状闭环型冠脉支架，支架外观设计、支架加工手段、支架的性能都基本接近国际水平，支架样品符合设计的理念，可以实现自膨胀功能。

Epithelium type tumour cell's Epithelium structure having various diversity the mammilla shape tubulous be in charge of the mammilla shape tape meritorious service slice a shape for instance.

恶性璋皮瘤的病理组织学分型有上皮型、纤维型和混合型三种。上皮型肿瘤细胞的上皮有各种不同的结构，例如乳头状、管状、管乳头状、带状功片状。

The first and second tubular portions comprise materials of different stiffness, with the tubular portions being connected to one another in end-to-end relation.

第一和第二部分包括管状不同刚度材料，管状部分被连接在终端到终端的相互关系。

According to the investigation of hydrophobic properties of ACNT films, we expect that it is not limited to ACNT films, all nanoscale tubular or fibrillar surface/interfacial materials with the alignment structure are probably superhydrophobic or super-amphiphobic through hydrophobic reagent treatment.

根据对阵列碳纳米管膜疏水性能的研究，我们预期，不限于阵列碳纳米管膜，所有其它的具有阵列结构的纳米级管状或纤维状材料，经过疏水试剂适当处理后，都可能会具有超疏水或超双疏效果。

Corolla tubular, tubular-funnelform, or salverform; lobes each with 1 or 2 basal scales; scales fringed with nonvascularized white fimbriae; plicae absent.

All specimens are of small size, mostly less than 150 μm in diameter. In gross morphology, those problematical microfossils consist of stout tubes with closed base, tiny internal mold of elongated tube, parallel clustered unbranching tubes, spicule-like structure with expanded circular base, and branching tubes of various bifurcating styles.

The contribution of water concentration on the growth of carbon nanotubes was investigated. Scanning electron microscopy results showed that the grown CNTs in CH4/H2 gas mixure had chain-shaped structure and the diameter was about 40—90nm. With the addition of proper amount of water, the diameter of CNTs became uniform, and the surfaces of nanotubes were fully covered with nano-sized node-like structures. When more water was added, branched carbon nanotubes were synthesized.

场发射扫描电子显微镜结果表明，不加水时，制备出的碳纳米管直径不均匀，分布在40—90nm之间，呈链节状的结构；加入少量水时，制备出的碳纳米管直径比较均匀，集中在70nm左右，表面为瘤状结构；当水的流量进一步增加时，得到的碳纳米管表面光滑，出现了枝状结构。
