It is found that the electric, field improves elongations in 2090 and 2090 + ce alloys markedly, especially in 2090 alloy, but has little effect on strengths. at the same time, the electric field lessenes percentages of intergranular delamination and increases transgranular fracture and microscopic plastic deformation. besides, the electric field makes both average particle size and its distributing range of 8 " phase smaller, and reduces the half width of pfz in aged alloys
研究表明：固溶電場可顯著提高2090合金及2090 + ce合金的延伸率，尤其是對2090合金，但對強度則無明顯的影響；同時，固溶電場減少合金的沿晶分層斷裂比例，並增加穿晶斷裂及微區塑性變形；固溶電場還使合金時效后相顆粒的平均尺寸減小、尺寸分佈范圍減小，並使pfz的寬度減小。 -
It is found that the electric field improves elongations in 1420 alloy markedly, but has little effect on strengths. at the same time, the electric field lessenes percentages of intergranular delamination and increases transgranular fracture and microscopic plastic deformation
研究表明：電場時效可在一定程度上提高1420合金的延伸率，但對強度則基本沒有影響；同時，電場時效減少沿晶分層斷裂比例，增加穿晶斷裂及微區塑性變形。 -
The microscopic plastic deformation of the local crazes cause the change of crack opening loads. therefore, the fatigue crack closure concept could be introduced. a crack closure model of mdyb - 3 pmma were recommended and phenomenologically formulated for positive and negative stress ratios separately, according to the testing results of fatigue crack propagation
本文討論了有機玻璃疲勞裂紋擴展機理，提出，銀紋的形成是裂紋形成和擴展的基礎，從微觀上解釋了裂紋形成和擴展的原因，並結合金相分析結果，明確提出塑變誘導閉合和粗糙誘導閉合是有機玻璃疲勞裂紋面閉合的兩個主要原因，成功的解析了裂紋面的閉合現象。 -
In present dissertation, firstly an analytical study on the force and deformation of an er single chain under poiseuille flow is presented from the point of microscopic view. an approximate solution of the poiseuille flow in a tube with rectangular cross is derived from galerkin approach. the balance equation of moment for the er chain is established to avoid using point - dipole model, which is not accurate enough in the case that dielectric particles are adjacent to each other
本文首先從微觀的角度，分析電流變鏈在poiseuille流動中的受力以及變形，分析過程中推導了矩形截面管內poiseuille流動速度分佈的galerkin近似解，並採用理論力學軟索模型對電流變變鏈的受力進行分析，從而避免了點偶極子近似在粒子相距較近情況下引起的誤差。 -
The authors have observed the progress of deformation and destruction of coal bodies in the experiment, carried out the macroscopic and microscopic research of the destruction progress of coal samples under load by means of servo electro - hydraulic loading test and electromagnetic radiation and audio emission monitoring, analyzed the cracking rate of coal samples under different situation, investigated the formation and development of cracking by use of fracture and elasticity mechanics, and thus established a sound experimental basis for the prediction by using gray classification
