We were taught to distinguish different decays by using a computer simulator of ATLAS, the LHC by recognising electrons, neutrinos and muon emissions from the interface of a real detector, and what was more, our team and only our team found Higgs boson from the simulator!!!

我们被教导通过计算机模拟的数据区分不同的衰变用，通过了LHC认识到电子，中微子和μ介子的排放量从一个真正的探测器的界面。我们的团队，只有我们的研究小组在反复实验六十次之后发现希格斯玻色子！

In addition, for different ground meson nonets, we discuss the effect of the flavordependent annihilation on the single-octet mixing angle and Schwinger's nonet mass formula.

另外，对于不同的基态介子九重态，我们讨论了味道有关的湮灭过程对单态—八态混合角及许温格九重态质量公式的影响。

The nonsymmetry effects can explain the problem appearing in the extention of the life time for the secondary cosmic ray,μ mesons; they also can explain the controversial problem who is more young in the famous twin paradox.

不对称性效应能解释次级宇宙线μ介子出现寿命延长的问题；也解释了著名的孪生子佯谬中谁年轻的争论问题。

The half life of the uncharged pion is 6??

中性兀介子的半衰期为6×？

For the pion case, this shows that the value obtained in QCD sum rules is only 50% of that determined by the equation of motion.

比如π介子的情形，QCD求和规则给出的上述结果约是运动方程要求的值的50%左右。

Two photons are created in the decay of the neutral pion.

双光子是在中性兀介子衰变中产生的。

Meanwhile, pion also achieved highly concentrations for it has been largely produced in high energy heavy collisions recently.

而π介子由于在近来高能重离子碰撞实验中大量产生，也吸引了人们的研究兴趣。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
