查询词典 beta

Each emission of an alpha or beta ray accompanies the transmutation of an atom; the energy communicated to these rays comes from inside the atom.

试想想，没有对危险阿尔法屏蔽-β需要射线，无高电压，是所有的塑料和金属零部件的生产造成的环境污染的需要。

Some nuclei, especially heavier ones, are unstable , or radioactive, emitting energy in the form of alpha rays, beta rays, or gamma rays.

有些原子核并不稳定，特别是较重的核，或称具有放射性，以α射线、β射线或γ射线的形式发出能量。

Some nuclei, especially heavier ones, are unstable, or radioactive, emit ting energy in the form of alpha rays, beta rays, or gamma rays.

有些原子核并不稳定，特别是较重的核，或称具有放射性，以α射线、β射线或γ射线的形式发出能量。

With the discovery of the radio-elements, physicists found themselves for the first time confronted with strange substances, minute generators of radiation endowed with an enormous concentration of energy; alpha rays, positively charged helium atoms, beta rays, negatively charged electrons, both possessed of a kinetic energy which it would be impossible to communicate to them by ''.

由于放射性元素的发现，物理学家们第一次发现自己面临许多陌生的物质——许多具有巨大的浓缩能量的、能够发生辐射的细微物质，如射线，即带正电荷的氦原子小射线，即带负电荷的电子。

The first round of that testing was the Alpha test. The second round is now the Beta test.

这样，运行于空间环境中的系统的设计目标就是在保证系统实时性

However, it is still difficult to find out the real reason of the increase of the keratinized gingiva during the orthodontic extrusion whether it is due to the proliferation of the gingival tissue or to its elastic nature, that is because the proliferation of the fibroblasts as well as the connective tissue changes in volume and the intra-fibers spaces were all immeasurable in most of the studies.

然而，仍然难以找到真正的原因增加的角化牙龈在正畸挤压它是否是由于扩散的牙龈组织或其弹性性质，这是因为增殖的成纤维细胞以及作为结缔组织的变化量和内部纤维空格都是不可估量的，大多数的研究。
