broken symmetry
解釋
破缺對稱性-
According to goldstone theorem, the goldstone bosons with zero mass will emerge as the chiral symmetry is spontaneously broken
由goldstone理論可知，當手征自發破缺時會生成零質量的goldstone玻色子。 -
In quantum chromodynamics ( qcd ), vacuum is not trivial, that is, vacuum carry quantum numbers. such a behavior is embodied by non - perturbative con - densates of quarks and gluons. since hadrons are excitations with respect to the vacuum, hadronic properties are ultimately related to properties of the vacuum. based on the vacuum structure, some hadron properties have been described well. in the low energy region, qcd has two very important proper - ties : chiral symmetry spontaneous breaking and confinement, which are closely related to the vacuum characteristics of qcd. much experiments and theoretical studies have shown that chiral symmetry spontaneous breaking is very important to understand the low - energy feature of the strongly interacting physics, and the quark condensates give an expression to chiral symmetry spontaneous breaking. according to goldstone ' s theorem, the goldstone bosons with zero mass will emerge as the chiral symmetry is spontaneously broken. there are two ways : inear and non - linear methods to carry out this constraint. in our paper, we will use the non - linear method
大量實驗和理論研究表明，手征對稱自發破缺對于理解低能強相互作用十分重要，而夸克凝聚又是導致手征對稱自發破缺的因素。按goldstone理論，伴隨手征對稱自發破缺應該會有零質量的goldstonebosons產生。而對于這一條件的實現有線性和非線性兩種方法本文將用非線性的方法將手征對稱自發破缺應用於su （ 3 ）模型即重子八重態，得出描述其強相互作用的手征對稱自發破缺lagrange密度。 -
If a magnetic field is switched on, the symmetry is broken.
如果加上磁場，就破壞了這種對稱性。 -
The inverse symmetry broken at the calculation of the dissociation energy using density function theory has been discussed
並探討了有關dft方法在計算體系離解能時的「反對稱性破壞」問題。 -
Moreover, the director distribution symmetry to the mid layer of nlc celliias been broken by the flexoelectric effect. a new parameter a is introduced to express the symmetry breaking and has been investigated in detail
此外，本文還證明了撓曲電效應還會導致指向矢分佈對中間層平面對稱性的破缺，引入並詳細研究了表徵對稱性破缺的參量。 -
Thus rotational symmetry of the microemulsion is broken and microemulsion becomes optical anisotropy. an understanding of the physical origins of such phenomena is of great practical and fundamental interest
