In chapter I, we introduce the Jordan-Wigner transformation in detail, and illustrate its applications with three examples: the one-dimensional S = 1 XXZ model; the bilinear-biquadratic SU(2) invariant S = 1 chain; and the ionic Hubbard chain in the strong coupling limit. In chapter II, we review the S = 1/2 transverse Ising chain in detail.

在变换后发现隐藏在自旋为1的系统里自旋为1/2的SU(2)对称性及广义的U(1)规范对称性；(3)通过将推广的强耦合极限下的一维离子型Hubbard 模型变换为SU(3)反铁磁Heisenberg 模型，严格论证了离子型Hubbard 模型从能带绝缘体到莫特绝缘体的转变区域中自发二聚化绝缘体铁电性相即键序波相的存在。

In addition to abundant shells and exotic items, another trait of this site is small and granulous slag remains and fired clay. Outside of these slag remains is different from other slag remains found in northeastern coastal areas.

出土遗物除大量贝壳与多种外来物外，另一特色为型态与一般东北角地区遗址中所见铁渣型态相异的细碎铁渣以及火烧红土，总重约20多公斤。

In late Tang period,influenced by west Asian great cutting Dao,each 'country' is more powerful because of this shape.Because it's hard to find iron and ironstone,a lot of sword was needed to re-smelted.Moreover the former shape didn't reach the new war condition,so it's abandoned and there's little exsited(only inscribed in Tang poems and Tang drawings).

二、在唐末五代十国时期，受中西亚大砍刀的影响，各"国"因为此刀型比原有唐刀更加结实有力，先后装备这种刀型，加上当时各"国"贸易流通受政治影响极大，铁和铁矿石很难买到，故须将大量的刀剑重新回炉炼制此新刀型，加上原有刀型无法适应新的战争条件，导致此刀型被废弃，故现存实物极少（只在唐诗、唐画中有描绘）。

It is the fluorosilicic ion that exsits in the slurry and plays an important role in flotation, fluorosilicic ion not only reacted with Fe〓 on the surface of aegirine to form ionic compound, but also formed stable Si-F bond in Si-O etching reaction. Only ionic compound was obtained when it was attached to hematite surface according to the theories of coordination chemistry, Compared with SiF〓, Fatty acid ion preferentially acts with Fe〓 on the minerals surface, therefore, SiF〓 Can't obstruct the adsorption of collector on the surface of hematite completly, but can reduce the flotation recovery of aegirine selectively.

运用FTIR、XPS等测试方法仔细研究了氟硅酸盐抑制剂对含铁硅酸盐钠辉石的选择性抑制作用机理，氟硅酸盐在弱酸性条件下对赤铁矿浮选的抑制作用很微弱，而对含铁硅酸盐钠辉石强烈抑制，从而扩大了两者之间的浮选差异；SiF〓是矿浆中起抑制作用的主要成分，SiF〓不仅与钠辉石表面的Fe〓形成离子型配合物，而且还与Si-O键形成稳定的Si-F共价键，而与赤铁矿表面只能形成离子型配合物，根据晶体配位场理论，与SiF〓相比较羧酸根离子将优先与矿物表面Fe〓发生配位作用，因此SiF〓的存在并不能完全阻碍捕收剂在赤铁矿表面的吸附作用，却能够选择性地抑制钠辉石的上浮。

Furthermore, there is a great phenotypic diversity among the new strains isolated from the same host. Different groups consisted of the new strains from the same host, some were Rhizobium, some were Bradyrhizobium, such as the new strains isolated from leguminous plants of AMkora Prain, Trifolium repens Lam, Aeachynomene Mica L, Indigofera bungeana Steud.

同时，攀西地区豆科植物根瘤菌的多样性还表现在某些来自同一种寄主植物根瘤菌的多样性方面，如分离自山槐、白车轴草、合萌、铁扫帚上的同一种寄主植物内的根瘤菌分别聚在不同的表观群；且来自山槐、合萌、铁扫帚上的根瘤菌既有快生型，又有慢生型。

It can be particularly used in situ remediation of groundwater and soil contaminated with halogenated organic compounds.
