本文从系统的角度，分析发展循环经济与产业结构调整之间的内在联系，以循环经济发展的微观、中观、宏观三个层次为基础，通过微观企业层面上改造价值链和中观层面上构建生态工业园来调整产业结构，推进循环经济发展，改变我国的经济发展模式，使我国从传统的产品经济模式，向资源经济模式转换，进而实现循环经济在整个社会层面上的大循环，从而找到在全社会建立一种以循环经济发展模式为核心的可持续发展的社会-经济系统的具体实践。

It connects different factories or enterprises by the way of transmitting material flow or energy flow, to form industrial symbiosis networks by sharing the resource and mutual exchange by-products. Under this pattern,"by-product" of one producing process may be the raw material of another process. In order to explore material closed circular, energy conservation system and minimum discharge of the waste, it set up the circular pathway by imitating the natural circular system as"producer—consumer-- decomposer"in the industrial system.

In this thesis, terahertz transmission properties through three kinds of simple sub-wavelength metallic structures, including single sub-wavelength metallic circular hole, single sub-wavelength metallic slit and double sub-wavelength metallic slits, are experimentally investigated in the far field by using our own THz time-domain spectroscopy system and are theoretically analyzed. Conclusions are obtained as follows:(1) a single sub-wavelength metallic circular hole exhibits the same terahertz transmission properties as that of round metallic waveguide, which are influenced by the diameter of circular hole and the thickness of metal foil.

It is found that the overall heat transfer coefficient of elliptic cylinder with k.0 is higher than that of a circular cylinder.At k=6.0,it has the maximum which is about 1.6 times that of a circular cylinder.At the same time,the drag coefficient drops down with the increase of k.For k=2.0,the drag coefficient is about 60％ that of a circular cylinder.

当k.0时，椭圆管的平均对流换热系数高于圆管；当k=6.0时，达到最大值，大约为圆管的1.6倍，同时，其阻力系数随着k的增大而减小；当k=2.0时，阻力系数约为圆管的60％。

In 1998, Longo described a method by which prolapsing hemorrhoids could be treated with a circular stapler, obviating the excision of either the anoderm or perianal skin. He postulated that the hemorrhoidal symptoms were primarily related to prolapse of the rectal mucosa and anoderm. The procedure for prolapsed hemorrhoids (PPH, a circular hemorrhoidopexy) resulted in simultaneous relocation and fixation of the hemorrhoids and anoderm. With the widening acceptance of hemorrhoids as prolapsed anal cushions, a circular hemorrhoidopexy has become a popular procedure for the treatment of symptomatic hemorrhoids.

在1998年Antonio Longo提出利用经肛门环形自动钉合器来治疗脱垂的痔疮，他认为痔疮的症状主要是因直肠黏膜及肛垫脱垂所引起，而环形的痔疮修补术可以将痔疮及肛垫组织重新定位回原来的正常位置，在随著普遍认为痔疮是脱垂的肛垫，环形的痔疮修补术已常用在治疗有症状的脱垂痔疮。
