Several isospin amplitudes are found to be larger than the one from BSW factorization method.

这表明B介子无璨弱衰变存在较大的末态相互作用。

It is in accordance with the prediction of QCD factorization approach.

在研究B介子非轻子衰变过程中，已有多种方法。

It foreshow, they are having relation that meson and ε field,μ field.

它预示，介子和ε0 μ0他们的关系。

GeV/c, the suppression is similar to that of light baryons and mesons.

在电子横动量约大于2 GeV／c区间，其相应的粲夸克强子横动量约大于4 GeV／c，电子谱的压低程度与轻夸克重子和介子相似。

In all these studies, the vacuum fluctuation on nucleon,Δ-isobar, and σ meson is considered.

在以上所有的分析中，考虑了核子、Δ粒子和σ介子的真空起伏。

An elementary particle in the lepton family, having a mass209 times that of the electron, a negative electric charge, and a mean lifetime of2.2?

介子轻子族中的一种基本微粒，其质量为电子的209倍，是一种负电荷，平均寿命为2.2？

People through nuclear reactions, have been synthesized 17 kinds of atomic number greater than 92 of the transuranic elements, and thousands of The new kinds of radioactive nuclides, and by high-energy and ultra-high energy-ray beam and the interaction of atomic nuclei and found hundreds of kinds of short-lived particles, namely, baryon, meson, lepton, and particle resonance states of these particles has led to a new field of study - the birth of particle physics since the age of .70, nuclear physics has entered a deep development and wide application of new, more mature stage, on the one hand the development of particle acceleration and detection techniques, expanding people's research in nuclear means, the other hand, nuclear technology to serve the national economy, for example, for the development and utilization of nuclear energy to provide more accurate nuclear data; the use of isotope tracer technique diagnosis and treatment of disease; the use of radiation and irradiation preservation of food, irradiation breeding .

人们通过核反应，已经人工合成了17种原子序数大于92的超铀元素和上千种新的放射性核素，并且通过高能和超高能射线束和原子核的相互作用，发现了上百种短寿命粒子、即重子、介子、轻子和共振态粒子，对这些粒子的研究导致了一门新学科——粒子物理学的诞生。70年代以来，核物理进入了纵深发展和广泛应用的新的更成熟的阶段，一方面发展粒子的加速技术和探测技术，扩充人们研究原子核的手段，另一方面将核技术服务于国民经济中，例如，为核能的开发利用提供更为准确的核数据；利用同位素示踪技术诊断和治疗疾病；利用射线及辐照技术保存食品、辐照育种等。

In this thesis, we have studied some decay modes of low-lying vector mesons.

本论文研究了低能标下矢量介子的一些衰变模式。

So, that meson and μ0 field,ε0 field, they will be concerning it.

因此，介子和μ0，ε0，他们将有关它。
