Fabrication and investigation of bioactive coatings on Ti alloys by micro-arc oxidation

医用钛合金由于其良好的材料力学性能以及化学、生物性能而被广泛用于骨科、齿科以及整形外科，但钛合金属于生物惰性材料，直接植入体内不能被组织细胞识别，会发生免疫排斥反应导致植入效果不佳。通过表面处理技术对钛合金表面进行改性，构筑具有生物活性以及生物相容性和其他相关性能的优异膜层，对医用钛合金材料的长期安全植入以及促进组织细胞攀附、增殖、分化和生长具有重要意义。 本论文在前期调研的基础上开发了一种制备钛合金微弧氧化生物活性黑色涂层的工艺，实现了钛合金表面改性，其中重点研究微弧氧化过程中电解液参数以及电源参数对膜层表面形貌以及组成、相结构、孔径、色度值、耐腐蚀性能、亲水性能以及力学性能等综合性能的影...Titanium alloys have been extensively used as orthopedic, dental and plastic surgery materials due to their excellent mechanical properties and biochemistry properties. However, the titanium alloys cannot be identified by tissue cells when implanted into human bodies due to their poor bioactivity.

The image and deification of Long (龍)in the Han dynasty (漢代)

Long (龍)is considered the symbol of China and the ancestor of Chinese people as well. Known as a god of water and sky，Long also has a great influence to history and the way people think about the world of East Asia. There have already been several studies about the origin of Long since its deification. However the previous researches which refer to reasons and the process of long\u27s deification are not enough. And the character of Long by Han dynasty，as an important reason of its deification，is still unclear

小钝头锥无粘平衡、非平衡绕流流场的数值分析

本文给出钝头细长锥无粘、平衡和非平衡高超声速绕流流场的数值分析。对存在化学反应的空气,考虑了13种气体组分和22个化学反应,包括N_2、O_2和NO的振动松弛与离介过程之间的耦合反应。头部亚-跨声速区和后身高超声速区分别用直线法和有限差分法进行计算。在来流条件M_∞=20～26,Re_∞=(p_∞u_∞α)/μ_∞=1.5×10~3～5.5×10~6(α为头部半径)的参数范围内,给出了绕流流场和等离子体鞘层诸特性,如激波形状、电子密度和电子碰撞频率等

The precedent recognition and studies of Long（龍）

This paper focuses on the precedent studies of Chinese Long （龍） and those derivative legends and cultures about it, which spread all over East Asia and even have a global influence nowadays. There are already many researches talking about the origin of Long and its spread, or about those pictures of Long picked up from excavated articles. But of these studies there are still some methodological problems such as a misunderstood starting point of what we think the Long is today, and also the easy means of combining the pictures and the historical texts.This paper shall attempt to discover a new method to find out the originof the recognition of today’s Long and those derivative legends and cultures about it.研究ノー

The Images of long （龍） on the Stone Reliefs of the Han Dynasty ― the episode of the first distribution area

It is common to look at the Chinese Han dynasty as being unified in every aspect. However according to some recent discoveries regarding Han political and financial systems in local and central authorities, it seems that this view is untenable. And what of Han culture? Was Han culture indeed united completely under the imperial government? This paper discusses these matters by looking at the carved images of long （龍）, or dragons on the stone reliefs of the Han dynasty. Through this study, the variations of the long carvings based on differing chronological periods and regions of the Han dynasty should become clearer.東アジアの歴史と動

One the indentification of the icon of animals: Take the icon of Long (龍) on the Stone Relief of the Han daynasty for example

This paper discusses the methods of identification of the icon of animals. The problem that how to identify the icons in the pictures precisely has come up to us, as the importance of images and pictures in study of history being claimed in latest years. And the icons of animals, especially those were created by people as fictions, are facing a serious situation of hard to be identified. Usually, to identify an icon of a fiction animal, we depend on our experience built of books and historical materials. But that could cause a problem as we always tend to ignore the time and place that the images or pictures were created. This paper will take the icon of Long (龍)on the Stone Relief of the Handynasty as an attempt to find out a more practical method to identify the icons ofanimals.東アジアの歴史と動態文部科学省グローバルCOEプログラム 関西大学文化交渉学教育研究拠
