查询词典 beta

Wu received many awards in recognition of her contributions to atomic research and the understanding of beta decay and the weak interactions, including being the first living scientist to have an asteroid named after her.

Enrico Fermi, who developed the theory of beta decay, coined the term neutrino in 1934 as a clever way to resolve the confusion.

发展了β衰变理论的恩里科费米，在1934年创造了一个词neutrino作为一个聪明的办法解决了中子名称的混乱。

First evidence for this third neutrino type came from the observation of missing energy and momentum in tauon decays analogous to the beta decay leading to the discovery of the neutrino.

首次在第三中微子类型的证据来自失踪能源和tauon衰变类似于β衰变导致了中微子观测发现的势头。

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。

In some kinds of beta decay, a nuclide loses surplus positive charge by emitting a positron (in the same event, a proton becomes a neutron, and neutrinos are also given off).

以某种贝它衰减，一个核素靠发出一个正电子失去剩余正电荷(在相同的事件中，一个质子变成一个中子，而且也发射微中子)。

The neutrino was first postulated in 1930 by Wolfgang Pauli to preserve the conservation of energy, conservation of momentum, and conservation of angular momentum in beta decay—the decay of an atomic nucleus into a proton, an electron and an antineutrino.

中微子是1930年由沃尔夫冈泡利为了保持能量守恒，动量守恒和β衰变---一个原子核（那时还没有认识到是中子）衰变成一个质子、一个电子和一个反中微子的角动量守恒，。

Among the Bayesian distribution, beta distribution is most widely used as a result of its simplicity and flexibility.

基于上述分析，本文在分析现有的概率信誉模型基础上，尤其是β分布信誉模型的基础上，探讨了一种基于高斯分布的形式化信誉模型。

This is a little odd considering that the Windows 7 developer distribution beta is not due out for several weeks.

这是一个很少考虑到奇数的Windows 7日开发商分布测试是不是因为出了几个星期。

Making full use of knowledge in manufacturing tolerance analysis combined with the beta distribution model is introduced and applied.

所用分析方法充分利用制造环境知识，把贝塔分布应用于公差设计。

Based on the definition and Beta distribution, a novel subject trust model is proposed, and an algorithm to combine recommendation trust is illustrated.

另一种是主观信任关系，主观信任恰当地描述了分布网络环境中实体间的信任关系，应用灵活。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
