Let us very briefly rehearse one or two facts about nuclear beta decay.

让我们非常简要地复述一下有关该β衰变的一两件事实。

A better idea springs from the weak force , which governs certain nuclear processes, including radioactive beta decay. In 1964, physicists found that the weak force is not quite symmetrical in its dealings with matter and antimatter, resulting in something known as CP violation .

比较好的意见是后来突然提出来的称为"弱力"的理论，这种"弱力"控制了某些核过程，其中也包括了放射性的β衰变。1964年，物理学家发现弱力在处理物质和反物质是不完全对称的，此种结果称为宇称不守恒。

First, it raises the prospect that the immemorial split on nuclear weapons between the old Labour right—embodied by Ernest Bevin, the post-war foreign secretary who was so keen to get a bomb "with the bloody Union Jack on top of it"—and the party's peaceniks, whose policy of unilateral disarmament contributed to Labour's unpopularity in the 1980s, may be revived in opposition.

第一个，它可能会带来工党内部对于核武器问题的分歧，以前工党曾经由战后外交大臣Ernest Bevin正面提出倾向于获得"让该死的英国国旗覆盖着"的原子弹，而他们的单边裁军政策导致了工党在80年代的失去执政的党内的反战分子们可能会反对Ernest Bevin所提出的关于获得原子弹的论调。
