查询词典 phenomenologically

Finally, we phenomenologically separate phase according to magnetic fields, the results is consistent with our new idea where we use the Hamiltonian with curved surface to analyze XY model. In chapter Ⅳ, we make two hypotheses: the system has one-step time correlation and two-step time correlation. We find the effect of Ratchet potential is similar to OSTC which changes the system's relaxation. TSTC may facilitate the system to move forward or backward along the nonlinear wave of the thermal fluctuation.

第四章，我们进一步作了两个唯象的假设：体系有一步和两步时间关联；发现Ratchet势与一步时间关联有相似效果——改变了体系对热噪声的驰豫；而两步时间关联项则能够促使体系在热噪声的非线性波形上定向&冲浪&，或者促使体系躲避热噪声的扰动保持在势阱底部。

By applying the above mentioned theoretical approaches in the secondhalf of this thesis, we study several phenomenologically interesting problems including the B meson nonleptonic decays, rare decays and the extractionof the CKM matrix element 〓. With the hypothesis of factorization, thetwo-body nouleptonic decays of B mesons are analyzed.

本文的后半部分应用上述理论进展，分别探讨与研究了B介子的非轻衰变，稀有衰变以及CKM矩阵元Vub的抽取等问题，在因子化假设下，我们分析了B介子的二体非轻衰变，并得到〓介子的衰变常数约为280 MeV。

Weibull distribution function is used to characterize phenomenologically the debonded probability of the interface, which is decided by the tensile stress of the particle. A partially debonded isotropic spherical elastic particle is replaced by an equivalent, perfectly bonded spherical particle, which possesses yet unknown transversely isotropic elastic moduli. The fictitious particles can be determined in such a way that their tensile and shear stresses will only vanish in the debonded direction.

认为颗粒增强金属基复合材料的界面脱黏受控于颗粒所受的拉应力，引入Weibull分布函数描述颗粒脱黏概率，且受单向拉伸载荷作用时，仅在沿受力方向的上下两侧发生部分界面脱黏，从而将部分脱黏的各向同性颗粒由一完好的横观各向同性颗粒来等效，建立了部分脱黏模型。

The damage represents complex mechanism. In this research based on T300/HT3 laminate structure, fatigue life is predicted phenomenologically, dealing mainly with in-plane stresses without accounting for out-of-plane failures such as craze. Fatigue modulus, based on damage mechanics, is used as a physical parameter which helps to describe the basic fatigue behaviors of unidirectional laminates and obtain expressions for cumulative damages defined by strains and stress. Based on some typical fatigue test data for unidirectional composite laminates, residual modulus sequence is found out.

本文以T300/HT3复合材料层压结构为研究对象，从唯象的观点出发，以损伤力学为基础构造损伤函数，考虑了剩余刚度和应变比率对复合材料的疲劳性能的影响，以这些变化着的机械性能作为损伤变量，建立了复合材料的疲劳损伤模型，基于层压板拉—拉疲劳试验数据，拟合出损伤模型中的参数，从而得到层压板拉—拉疲劳损伤变化规律，并建立损伤变量与内部损伤及疲劳寿命的联系，从而预测常幅应力作用下疲劳寿命。

Si alloy thixotropic deformation behavior has been established. Phenomenologically, An internal variable framework effectively combines the microstructure level structural kinetics with the maroscopic flow behavior.

采用自制的半固态合金固液两相区力学性能测试装置进行半固态Al-7.0％Si合金的触变力学性能的研究，建立了半固态Al-7.0％Si合金触变变形行为的幂律模型。

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
