An axial vector may itself enter into a vector product.

轴矢量自身可参与矢积。

The paper is made up of two parts:Firstly, we studied systematically the radiative decays of light vector mesons:〓in the framework of a U(3)L×U(3)〓chiral theory of mesons. In this theory, low-lying pseudo scalar, vector, axial vectormesons are introduced as the bound states of the quark fields.

全文分轻味矢量介子辐射衰变和重味矢量介子的软π衰变两部分：首先，我们在U(3)〓×U(3)〓手征介子理论的框架内，系统的研究了轻味矢量介子ρ，φ的辐射衰变〓在该理论中，低能的赝标，矢量和轴矢介子场是作为夸克场的束缚态被纳入。

In studying the linear response of the dressed quark propagator in the presence of the variable external field, we derive a general expression for the vacuum susceptibility, based on the two-point external field formula in the Quantum Chromodynamical sum rule. The expressions we have derived for the calculation of vacuum susceptibility are model independent. Then we use the expressions to calculate the renormalised axial vector, vector and tensor vacuum susceptibilities.

接下来在研究夸克传播子在外场中的线性响应时，我们利用QCD求和规则两点外场公式推导出了一般的计算真空磁化率的公式（以变化的轴矢量外场为例），我们这里推导出的真空磁化率的计算公式是模型无关的。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
