phenomenologically 中文意思是什麼
-
So cross section and particle production are not calculated consistently. and it is difficult for gri5ov - regge theory to include hard process. the parton 6ased gri6ov - regge theory provide a solution : elementary scatterings happen in parajlel, described phenomenologically as pomeron exchanges
因此，在nexus中pomeron的色弦形成方式就與其它模型很不相同；即使只有一個pomeron交換，色弦的端點也是海夸克和反夸克，而不是價夸克。 -
In this research, fatigue life of laminate composite is predicted phenomenologically, dealing mainly with in - plane stresses without accounting for out - of - plane failures such as delamination. fatigue modulus is used as a physical parameter which helps to describe the basic fatigue behaviour of unidirectional laminates and obtain expressions for cumulative damages defined by strains. based on some typical fatigue test data for unidirectional composite laminates, a cumulative fatigue damage model is presented for predicting the fatigue life of multidirectional laminates with arbitrary stacking sequence under complicated fatigue loadings
本文以碳纖維/樹脂基t300 / qy8911層壓結構為研究對象，從唯象的觀點出發，以疲勞模量為參量構造損傷函數，基於幾組最典型的單向板疲勞試驗數據，建立單向板在多軸循環應力作用下的疲勞壽命模型，並以此為基礎，發展同種材料體系的任意鋪層形式的多向層壓板在復雜循環載荷作用下的疲勞壽命預測方法。 -
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。 -
Moving from single dislocations to ensemble effects, recovery and polygonization are reviewed. recrystallization is also introduced and described phenomenologically
由單一差排進而轉往整體效應，並回顧回復及多角形化。亦由現象面介紹及描述再結晶。
