在主元素氧化物和微量元素、稀土元素含量上，克雷克特山、鸟角和博尼湖南岸的碧玄岩、碱玄岩成分比较类似，均具有较高的MgO、TiO〓、过渡元素和相容元素，较低的SiO〓、Al〓O〓、K〓O、Na〓O、不相容元素和稀土元素；罗德角和伊万思角安粗岩雷同，它们具有较高的SiO〓、Al〓O〓、Na〓O、K〓O、稀土元素和不相容元素，较低的MgO、TiO〓、过渡元素和相容元素，但五地区火山岩几乎具有一致的Sr、Nd同位素比值，〓Sr/〓Sr＝0.703115-0.703344、〓Nd/〓Nd＝0.512892-0.513076，在Pb同位素比值上，五地区的〓Pb/〓Pb＝18.664-19.913，其中碧玄岩和碱玄岩比安粗岩的比值稍低。

Interlayer oxidized zone can be divided accurately by Fe_2O_3, Fe_2O_3/FeO and U parameters. We can correct the field macroscopic color zoning by combining the macroscopic zoning and microscopic zoning. Univalent major elements components(Al_2O_3, SiO_2, K_2O, Na_2O) show remarkable activity at the process of interlayer oxidizing, their contents are variable and mingled in different zones and it can't be used in zoning. But we can speculate the developmental degree of interlayer oxidized zone and uranium mineralization according to the concentration trends and variation characteristics of sensitivity group, activity group and their ratios .(3)The comparatively steady elements such as lithiphile elements, sulfophile elements and high field strength elements change regularly at the process of interlayer oxidation except some radioactive elements. Trace elements and rare earth elements commonly enrich in thin rock clast such as mudstone, in which the enriched elements species are more than those in the whole rock, which indicate that the regeneration action in caulking matter are more deep than that in whole rock at the process of interlayer oxidation, and the reallocate intention of trace elements in main minerlized rock in Tuha basin are more intensive than that in Yili basin at the process of deposition ,diagenesis and later changes .

根据化学蚀变参数PC值和分离迁移位等将常量元素组分分为敏感组分组、活动组分组、次活动组分组和惰性组分组，不同组分可分别用于讨论层间氧化带低温地球化学中不同问题；敏感组分(变价元素组分Fe_2O_3、FeO)和U在层间氧化带中迁移富集规律明显，Fe_2O_3／FeOFe~(3+／Fe~(2+)比值具分带判别能力，配合U含量对层间氧化带进行较准确的分带，可克服野外宏观颜色分带偏差：提出Fe~(3+)／Fe~(2+)分带判别值在不同盆地、不同地段不同，除受氧化作用控制外，流体酸碱度不同也是重要因素的观点，对找矿实践有实际指导意义；活动组分(Al_2O_3、SiO_2、K_2O、Na_2O)在层间氧化作用过程中具有较明显的活动性，其含量值变化跳跃，在不同分带相互交织，不具分带指示意义；但利用敏感组分、活动组分及其比值在层间氧化带中的变化特征可推测层间氧化带发育的完善程度及其含矿性；次活动组分组(CaO、MgO、MnO_2)含量低，变化规律性差；惰性组分组(TiO_2、P_2O_5)含量低，活动稳定，可用来反映沉积物源特征。

This project studies the scale-dependent deformation behavior of the metal matrix composite, the void nucleation and void growth mechanisms at the micron/submicron scale. The main results are:(1) In prophase, growth and coalescence of the void embedded in the graded matrix are analyzed in detailed;(2) Based on the infinite solid model containing a micro-void, coupling effects of the void shape and the void size on the void growth are studied carefully, the results show that it seems to exist a critical equivalent void radius, which is associated with the material length. When radius of a microvoid is close to or smaller than the critical void radius, the micro-void growth rate is essentially eliminated;(3) The coupling effects of the particle shape and size on the mesoscopic stress fields within the particle and matrix are also investigated by introducing the conception of inclusion/matrix interfacial energy. The results show that the stress concentration factors within the particle and on the matrix/particle interface are also strongly size-dependent,so the void nucleation mechanism is size-dependent.(4) By employing a specific orthogonal curve coordinate frame and a 'kernel function' conception, a 'unified method'solving the spheriodal and spherical void problems is suggested; by this unified method, size-dependent plastic potentials of the porous materials containing the spheriodal or spherical voids are obtained, which extend the traditional Gurson model for the spherical void and GLD model for the spheriodal voids to the micron scale.(5) Based on the RVE model containing the spheriodal or spherical particles, the influences of the particle shape and size on the size-dependent mechanical behavior of metal matrix composite are studied.

中文摘要：本项目对金属基复合材料在微细观尺度下的尺度相关变形行为、孔洞形核及长大的机理和模型进行了研究，取得了如下主要结果：1）在前期研究中，探讨了基体的梯度分布对孔洞长大和聚合的影响；2）基于含孔洞的无限大体模型，探讨了孔洞形状和孔洞尺寸对其长大的耦合作用，结果表明：可能存在一个与材料特征长度相关的临界孔洞尺寸，当椭球孔洞的等效半径小于临界孔洞半径时，孔洞的长大受到明显抑制；3）通过引入基体/夹杂界面能的概念，分析了夹杂尺寸、夹杂形状对材料细观应力场的耦合影响，结果表明：颗粒内部和界面上的应力集中因子强烈地依赖于夹杂的尺寸和形状，因此，孔洞的形核机理是尺寸相关的；4）采用一种特殊的正交曲线坐标系和引入"核函数"的概念，"统一"地得到了含椭球和球形孔洞的材料的尺寸相关塑性势，它将传统的Gurson球形孔洞模型和GLD椭球孔洞模型推广到微尺度范围；5）基于含椭球和球形夹杂的体胞模型，初步研究了夹杂形状、夹杂尺寸对金属基复合材料尺寸相关力学行为的影响。

Most conventional methods for the extraction of substrate network were based on the use of frequency behavior of Y22 + Y21. However, we found that the feedback signal through the internal circuit elements makes the conductance of the substrate network underestimated while makes the susceptance of the substrate network overestimated. If conventional methods are directly performed on large area SiGe HBTs, a negative effective substrate resistance will be extracted. In the first part of the thesis, a new extraction method for the substrate network parameters of SiGe HBTs is proposed. When extracting the substrate network parameters, the feedback signal through internal circuit elements is considered. All the circuit elements of substrate network are extracted from Ysub instead of Y22 + Y21. The extracted substrate network parameters show a different bias dependence as compared to the conventional methods. By using a simple n+-p junction, we successfully explained the extracted bias dependent substrate network parameters. We developed a series linear regression equation to extracted the intrinsic circuit elements from the ABCD parameters. Compared with the conventional methods which extracted the circuit elements from Y-parameters or Z-parameters, the proposed method is much simple and easy to implement in the computer programs.

传统方法在萃取基板网路参数时，常常由所量得的Y22 + Y21来著手，但我们的研究发现，利用Y22 + Y21的频率关系来萃取基板参数时，基板网路的电导会被低估而基板网路的电纳则会被高估，另外传统基板网路参数萃取方法在萃取大尺寸元件基板网路参数时会得到负值基板等效电阻，以上的非理想效应皆因忽略部份信号会经由本质参数对基板网路做回授的影响，因此本论文中提出一个新的基板网路参数萃取方法，在萃取基板网路参数时考虑了由本质参数所回授的信号，并且由Ysub而非Y22 + Y21萃取基板等效电阻、基板等效电容及基板与集极空乏电容，成功的解决上述的一些非理想效应，所得到的基板网路参数与集极偏压的关系与传统方法所得的趋势相异，经由一个简单的模型成功的解释了所萃取得到的基板网路参数与偏压的关系，在萃取本质参数时，我们舍弃传统萃取方法中常用的Y参数或Z参数萃取方程式，而改用ABCD参数，并提出一系列的线性回归方程式，萃取所有的本质参数，与传统方法比较起来，比较简单而且容易建立在使用者的参数萃取软体中。

Taking Bendong and Xiqiu granitic bodies as an example, the thesis expounds geochemical characteristics of mantle-derived type granitoids in Sourthern China in REE and trace elements as follows: lower ∑REE, obvious fractionation of LREE and HREE, negative anomaly of Eu, relative higher ∑LREE/∑HREE,〓 and 〓 ratioes, rich in transitional elements and poor in large-ion lithophile and immobile elements compared with acidite means by Vinogradov.

In this study, the genomic structure and regulatory elements of ApoD from 10 representive species including protozoan, invertebrate, protochordate and vertebrate were analyzed and compared. The genomic structure of ApoD is less conserved in organisms from protostome to deuterostome invertebrates, while it is highly conserved among chordates including amphioxus and verebrates. All four conserved cysteine residues are present in amino acid sequence of deuterostome ApoDs, while there are only two cysteine residues in amino acid sequence of protostomes ApoD. Structure divergence between protostome and deuterostome ApoD proteins suggests their function difference. The majority of regulatory elements are present in nearly all organism ApoD genes ranging from unicellular protozoan to mammals, suggesting that ApoD plays a very fundamental role, and possesses a conserved regulatory mechanism. However, there also exist some specific regulatory elements, which are present only in certain species and may perform some special roles.ApoD mRNA expression in murine NIH/3T3 fibroblasts exposed to various stresses such as as hydrogen peroxide and UV light shows dose-dependent increase. And a fly homolog of ApoD, Glial Lazarillo, whose overexpression results in increased resistance to hyperoxia as well as a extension of lifespan under normoxia and resistance to starvation without altering lipid or protein content.

本文首先从生物信息学角度对分属于原生动物、无脊椎动物、头索动物和脊椎动物类群的10种动物ApoD的基因结构及调控区的调控元件进行分析及比较，发现：(1)ApoD基因外显子-内含子结构从原生动物草履虫到原口动物再到后口动物海胆的进化过程中不保守，但在分析的几种脊椎动物中相当保守；(2)文昌鱼ApoD基因扮演从无脊椎动物到脊椎动物承上启下的角色，可能代表了脊椎动物ApoD基因原型；(3)四个半胱氨酸保守位点在后口动物中都存在，而在原口动物中只存在两个，原口、后口动物ApoD蛋白一级结构上的差异反映蛋白功能上可能也存在一定差别；(4)调控区大多数主要调控元件为不同动物共有，说明ApoD主要功能及其表达调控在进化中相当保守；(5)ApoD基因个别调控元件是随着物种进化而出现并开始发挥相关作用，如SF-1；还有一些调控元件在进化过程中还没有发现其规律，这说明ApoD某些功能和基因表达调控模式可能因物种不同而存在一定的差异。
