Theobserved strain is 10~2 times as local point strain at the same observed stress.This indicates that macroscopical symmetrical rock is quasi-brittle materialwith microcosmic heterogeneousness and its macroscopical mechanicalbehavior is the results of reciprocity and magnification between microcosmiccharacteristic, not simple sum.(4) The degree of irregularity of strain increases with the number of cycle.But degree of irregularity of transverse strain fluctuates larger at the samecycle. Moreover degree of irregularity of transverse strain is larger than that ofaxial strain. This shows that deformation and failure of rock is process ofevolvement of small crack. Small crack evolves from even and out-of-orderstatus to heterogeneous and ordinal status.(5) Ultrasonic speed decreases with the number of cycle. The decreasecourse is such: Firstly, ultrasonic speed fluctuates in a steady scope in somecycles; And then ultrasonic speed quickly decreases to a certain more smallvalue; Afterwards in succedent cycles, ultrasonic speed fluctuates about thevalue. That is to say, ultrasonic speed fluctuates and decreases at intervals ofcycles. In deformation process of rock, quantitative change and qualitativechange of its small crack evolvement carry through crosswise.(6) Strength and modulus of rock decrease with exponential function asscale of specimens increases.
同一表观应力下,局部点应变与表观应变相差可达2个数量级,表明宏观上均匀的岩石是具有细观特征的准脆性材料,其宏观力学行为是细观特征相互作用、放大的综合结果,而不是简单的叠加;(4)岩样轴向应变不均匀程度和横向应变不均匀程度随循环次数的增加渐进增大,但是在同一个循环内,横向应变离散系数随应力的变化波动较大,且同一循环级别下,横向应变不均匀程度大于轴向应变不均匀程度,表明岩石内部微裂纹的演化是岩石变形破坏的本质特征,这一演化表现为微裂纹从均匀无序分布逐渐向非均匀有序发展;(5)随循环次数的增加,所有岩样内部超声波速会出现衰减,衰减过程表现为在某几次循环内超声波速在某一相对范围内波动,然后急剧减小到某一较小值,在随后的循环内,超声波速又会保持在这一较小值附近波动,即超声波速表现为波动和急剧减小间隔形式衰减,表明从宏观看来平稳的岩石变形过程,内部结构演化过程(微裂纹发展及其相互作用)却表现为均匀量变和突发质变不断交叉进行的现象;(6)岩石强度和弹性模量随尺度增大呈指数函数规律减小。

The results indicate that the flow stress of the alloy increases with increasing strain rate and decreasing deformation temperature. The flow stress increases with increasing strain until the stress reaches the peak value, then the flow stress remains constant, which indicates that dynamic recrystallization happens during deformation. The flow behaviors are described by the hyperbolic sine constitutive equation, and the activation energy calculated is 337.75 kJ/mol. The as-forged microstructure consists of refined α2/γ and γ grains, and the grains are much homogeneous than before. The B2 phase distributes uniformly at the grain boundary of α2/γ and γ grains. The B2 phase decreases with increasing deformation temperature.

The UV and IR spectroscopic studies of the monomer films showed that the photoreaction ratio of monomer (about 50%) was higher than the corresponding photosensitive polymer (about 10%, PVCi). The polarized IR spectra proved that obvious anisotropic absorption was displayed in the irradiated photosensitive film. With polarizing microscopy method, we found that these kinds of photoalignment films exhibited good alignment ability, and the stability of the photoalignment film could reach about 100℃. 2 A photosensitive self-assembled monolayer was fabricated that contained photo-cycloadditable groups, such as, coumarin and cinnamate. The reaction process were detected by contact angle method because the IR absorption of monolayer was very weak. The photosensitive self-assembled monolayer promote uniform alignment of nematic liquid crystals by LPUV, and it thermal stability could reach about 130℃. 3 A cationic bolaform amphiphiles was synthesized that had two photosensitive double bonds, and can be polymerized by ultraviolet. A layer-by-layer self-assembled deposition film was prepared in aqueous solution by using this material and poly (sodium 4-styrenesulfonate). The UV-Vis. spectra proved that the multilayers film was uniform and layer-by-layer. When LPUV irradiated the film, the photopolymerizable double bond underwent [2+2] cycloaddition, and the production of the reaction distributed along the polarized direction of incident LPUV. Polarized UV-Vis. spectra indicated that the irradiated self-assembled multiplayer film was anisotropic, and the dichromic ration is about 0.09, it is higher than the spin-coating method of photosensitive polymer or monomer. We used this anisotropic film as alignment layer of nematic liquid crystals, and obtained a uniform and stability alignment result, the static contrast ratio is about 100, which is very close to application of liquid crystal device. This thesis is an instance that the photochemical material was used in the physics region of liquid crystals, the route that was from photosensitive monomer, self-assembled monolayer film to self-assembled multiplayer film was undergone, by this logical research method photoailgnment of liquid crystal was extended and consummated.

Results: Most synovial sarcomas located in the extremities close to joints. Synovial sarcomas detected by radiography typically appeared as round, oval or multilobulated juxtaarticular soft-tissue masses with calcification in some cases. The most common CT appearance of synovial sarcoma was heterogeneous deep -seated soft-tissue mass with attenuation similar to or slightly lower than that of muscle. On T1WI, synovial sarcomas typically appeared as prominently heterogeneous multilobulated soft tissue masses with signal intensity similar to or slightly higher than that of muscle. On T2WI, synovial sarcomas appeared as prominent heterogeneity with predominantly high signal intensity.
