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.

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.

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.

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.

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 )播放在线你懂、"V TO V"、"V+ adverb+ V"亚洲一区二区区、"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欧美在线情色、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.

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).

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. It will solve the difficulty that establishing the immunoassay of Celangulin V. 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.
