alpha ray

These tools include the alpha particle X-ray spectrometer ( apxs), which measures elemental composition, and the Mars hand lens imager close-up camera, or Mahli.

这些设备包括阿尔法粒子x光分光仪，其可以检测元素组成，以及火星手持透镜成像器近景摄像机，或简称mahli。

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.

每一次a射线或b射线的放射都伴随着原子的蜕变，因为赋予这些射线的能量来自于原子的内部。

we have studied the relationship between gamma specific activities of natural radionuclides and alpha and beta ray level in building materials used in interior decoration, and the saturated thickness of beta ray from the surface of different materials.

进行了各类建材表面a、b辐射水平和其天然放射性核素g比活度关系的研究和不同饰材表面b辐射水平的饱和厚度研究。
