The results indicate that the effect of alloying elements V and Cr on mechanical properties at room-temperature, creep behavior and microstructures are similar. With increasing contents of V and Cr, their mechanical properties produce little change, the creep resistant property decreases and microstructure grows, which is mainly due to their characteristics of β-stability element and smaller atomic radius compared with Ti. On the contrary, the effects of V and Cr on the thermal stability are quite different. With increasing V content or decreasing Cr content the thermal stability for the alloy becomes better, which may be due to the different solution characteristics of V and Cr element in titanium alloy that V belongs to isomorphous β-stability element and Cr belongs to eutectoid β-stability element.

结果表明：合金元素V和Cr对Ti40合金室温力学性能、蠕变行为和组织的影响具有相似性，即随V和Cr含量的降低，合金室温综合力学性能变化不明显、抗蠕变能力减弱、组织粗化：这与V和Cr同属于β稳定元素、且原子半径都小于Ti原子有关；而V和Cr对于热稳定性能的影响则完全相反，V含量的增加或Cr含量的降低含金热稳定性能优化，其主要原因可能与V属于同品型β稳定元素而Cr属于共析型β稳定元素有关。

Therefore the dispersion curves obtained in the field are primarily consisted of the first mode. For a heterogeneous elastic solid consisting of three homogeneous layers whose interlayer has low velocity, the phase velocity V〓 of the first mode will also close up to the Rayleigh wave velocity of the bottom layer when frequency f→OHz, but V〓 of the first mode will close up to the shear wave velocity of the interlayer when f→∞, and there is a cut-off frequency at high frequency region for the first mode and V〓 close up to the compressional velocity of interlayer when interlayer is liquid.

当三层固体介质中存在软夹层时，若f→OHz，则其基阶模式的相速度V〓→V〓（V〓为最底层介质的瑞利波速度）；若f→∞，其基阶模式V〓→V〓（V〓为中间层介质的横波速度）；若三层介质中存在液体夹层，当f→OHz时，基阶模式V〓→V〓，而基阶模式在高频段存在一个截止频率，截止频率处的瑞利波速度V〓→V〓；由此可判定，野外实测的相速度频散曲线不仅有基阶导波模式，同时还应有高阶导波模式波的存在，接收信号中存在模式间的跳跃，因此频散曲线会产生"之"字形现象。

The first chapter, main instead " duo-ring " condition of " every maximal left ideal is GW-ideal " condition,study strongly regularities of GP-V-ring on this condition.lt is shown that (1) R is strongly regular iff R is left GP-V-ring whose maximal left ideals are GW-ideal.(2)R is strongly regular iff R is left GP-V-ring whose maximal right ideals are GW-ideal. The second chapter, generalize some results of GP-V-ring to GP-V-ring, discuss regularity of GP-V-ring.It is shown that (1) R is left self-injective regular with non-zero socle iff R is left GP-V -ring with Soc = Soc and R contains an injective maximal left ideal.(2)R is regular ring and every maximal essential left ideal is ideal iff R is left GP-injective left GP-V -ring and every maximal essential left ideal is ideal.

第一章主要将"duo-环"条件替换成"每一极大左理想是GW-理想"条件，研究在此条件下，GP-V-环的强正则性，证明了：(1)R是强正则环当且仅当R是左GP-V-环且R的每一极大左理想是广义弱理想；(2)R是强正则环当且仅当R是左GP-V-环且R的每一极大右理想是广义弱理想，第二章，主要将GP-V-环上一些结果推广到GP-V′-环上，讨论GP-V′-环的正则性，证明了：(1)R是左自内射正则环且Soc≠0当且仅当R是包含内射极大左理想的GP-V′-环，且Soc=Soc；(2)R是正则环且每一极大本质左理想是理想当且仅当R是左GP-内射的左GP-V′-环且每一极大本质左理想是理想。

Then we apply it to a C-module V, where V is a n-dimensional vector space and the operator from C×V to V is defined by a linear transformation T of V, then we get a unique factorization of V and a right basis under which the transformation matrix of T is T's Jordan canonical form.

然后把它应用到一个具体的C-模V，其中V是n维线性空间，C×V到V的映射由V中的一个线性变换T定义，从而得到V的一个唯一分解，再结合线性代数有关知识给出V的一组基，T在这组基下的变换矩阵恰为T的Jordan标准形。

Therefore, on the basis of objective description of corpus example, this paper study and analyze the condition of "free form" and "bound form" of the verbal phrases such as "V + Particle + N"、"V+ complement"(including:"V+ trend complement","V+ result complement","V+ extent complement" and "V+ action-measure complement )、"V TO V"、"V+ adverb+ V"、"V of V "and "V+ D".At the same time, from the semantic and pragmatic perspective this paper discuss the conditions and causes from "bound form" to "free form",concluding that particle dynamics、exclamation at the end of the sentence、adverb and follow—up of the language and so on can act as the conditions from the bound verbal phrase to the free verbal phrase. The main reason for these conditions is rich in the amount of the sentence, making semantic self—contained; Finally, this paper simply describes the theoretical and practical significance of the phenomena of "free form" and "bound form in the aspect of verbal phrase; at he conclusion of the article, the author of the text further sum up the content and coverage and raise her own views of the text of underdevelopment and the questions yet continuing to study.

因此，本文接着在语料例证的客观描述基础上，针对"v+动态助词+N"、"V+补语"(包括："V+趋向补语"、"V+结果补语"、"V+程度补语"、V+动量补语)、、"V来V去"、"副词+V"、"V的V"、"V+D的"等动词性短语的"粘着"和"自由"的情况做了探讨分析，并且从语义和语用两个角度探讨了"粘着"向"自由"转化的条件及原因，认为动态助词、句末语气词、副词、后续语段等等都可以充当粘着的动词性短语向自由的动词性短语转化的条件，其主要原因则是这些条件丰富了句子的信息量，使得语义自足；最后，文章简要地论述了研究动词性短语的"自由"和"粘着"现象的理论意义和实践意义；在文章的结语部分，作者就文中所论述的角度和涵盖的内容做了进一步的总结，并对文中存在的不足和有待于继续研究的问题提出了自己的看法。

For any two vertices u and v of a graph G, a u-v geodesic is the shortest path between u and v. The set I consists of all vertices lying on a u-v geodesic. For SV, I is the union of all sets I for vertices u, v∈S. The geodetic number g is the minimum cardinality among the subsets S of V with I=V.

Chemiluminescent immunoassay is one of the advanced immunoassay ofnon-radioisotopic immunoassay because of its high sensitivity, wide dynamic range,high accuracy, stable labeled protein, full automation and extensive application field.CLIA using acridinium ester derivatives as chemiluminescent label has advantages oflow background, high signal-to-noise ratio, no need of catalyst and simpleluminescence system. Different aspects associating the DMAE·NHS-based CLIA were studied in thisthesis, including synthesis of acridinium ester, chemiluminescentcharacteristics of DMAE·NHS, labelling antibody or streptavidin with DMAE·NHS,two-site sandwich chemiluminescent immunoassay for TSH, two-sitesandwich chemiluminescent immunoassay involved biotin-streptavidinsystem for TSH, and competitive chemiluminescent immunoassay usingbiotin-streptavidin system for TT〓. The desired acridinium ester, DMAE·NHS, was synthesized according to thereference method with some modifications. The products were identified by IR, NMR,MS and elemental analysis. In our method, KOH was used in place of NaOH tosynthesize benzyl ester of 3,5-dimethyl-4-hydroxybenzoic acid,2',6'-dimethyl-4'-(n-succinimidyloxycarbonyl) phenyl-acridinium-9-carboxylate waspurified on a silica gel column with chloroform/ethylacetate(4:1, v/v) as eluent andfurther purified by triturating with hexane/acetone(2:1, v/v).

DMAE·NHS的合成是本论文的关键和难点，我们对文献方法进行改进：文献方法用氢氧化钠与3，5-二甲基-4-羟基苯甲酸反应制得3，5-二甲基-4-羟基苯甲酸钠，再用3，5-二甲基-4-羟基苯甲酸钠与苄氯作用制备3，5-二甲基-4-羟基苯甲酸苄酯，我们用氢氧化钾代替氢氧化钠，使合成取得成功；在合成2'，6'-二甲基-4'-苯基-吖啶-9-甲酸酯时，文献方法对粗产品进行两次硅胶柱层析纯化，第一次柱层析用氯仿／乙酸乙酯(4∶1，V∶V)作溶剂和淋洗剂，第二次柱层析用己烷／丙酮(2∶1，V∶V)作溶剂和淋洗剂，按照文献方法得到的不是所需要的化合物，我们只进行第一次柱层析纯化，然后用己烷／丙酮(2∶1，V∶V)进行研磨，过滤，洗涤，除去溶于己烷／丙酮(2∶1，V∶V)的部分，得到所需要的产品。

Important advance was made to Celastrus and ceangulin V after 20 years studies, but the target of Celangulin V was not verified and the metabolic dynamic of Celangulin V in organism was not touched because of the technique difficulty in testing and analysis of trace Celangulin V in organism.

The immunoassay of Celangulin V including the synthesis of artificial antigen, the preparation of antiserum, the immunoanalysis location of Celangulin V and the quantitative immunoassay of Celangulin V were studied systematicly in this paper.

苦皮藤素V是从卫矛科植物苦皮藤中分离出的一种具有杀虫活性的天然产物，可能作用于一类新的作用靶标。20多年对苦皮藤及苦皮藤素V的研究已取得了重要进展，但迄今还没有证实苦皮藤素V的作用靶标，对苦皮藤素V在生物体内的药代动力学研究也尚未涉及，这些方面的研究因为对痕量苦皮藤素V在生物体内分析、检测存在技术方法上的困难而受到限制，建立苦皮藤素V的免疫分析技术则可解决这些问题。
