您要查找的是不是:
- The new mass relation holds not only for the ideal-mixing nonets but also for the nonideal-mixing nonets. 这种包含味道有关的夸克偶素湮灭修正的新的质量关系,不仅适用于理想混合的介子九重态,也适用于非理想混合的介子九重态。
- In the framework of quarkonia-quarkonia mixing, considering the effect of the flavor-dependent transitions between quarkonia, the new mass relation of a meson nonet is presented. 摘要在介子-介子混合的框架下,考虑到夸克偶素间的湮灭跟味道有关这种效应,给出了一种新的介子九重态成员间的质量关系。
- We found that binaries make the population look younger by about 20%.We have made a systematic study of binary evolution of Case B and given the initial - final mass relation. 我们发展了自已的演化星族合成模型,并首次在模型中考虑了双星的影响,发现双星让星族看起来更年轻(20%25左右)。
- It indicates that a correct mass relation of a meson nonet (especially for the non ideal-mixing meson nonet) should incorporate the effect of the flavor-dependent quarkonia annihilation. 这表明,一个正确反映介子九重态(特别是非理想混合的介子九重态)成员间质量关系的公式,应该包含夸克偶素间的湮灭跟味道有关这种修正。
- Lemming: any of various small, thickset rodents, especially of the genus Lemmus, inhabiting northern regions and known for periodic mass migrations that sometimes end in drowning. 旅鼠,一种体形短小但很健壮的啮齿目动物,尤指旅鼠属动物。它居住在北方地区,以其有时以淹死来结束生命的季节性群体迁徙而闻名。

- From the mass formula of T_3~3 breaking, one can find that the SU(6) symmetry gives the mass relations between different spin levels of the same strangeness analog states. 利用T_3~3破坏的质量公式,对SU(6)给出了同类奇异相似态不同自旋的能级间的联系。
- The inertia tensor is similar to mass, but whereas mass relates to the change in position of an object, the inertia tensor relates to the change in rotation of an object. 下一步我们设置物体的一些其它属性:质量和惯性张量。一个物体的质量表示有多“重”,它是相关于在场景里的物体。
