原子核的

Radioactive series: Any of four sets of unstable heavy atomic nuclei that undergo a series of alpha decay and beta decay until a stable nucleus is achieved.

放射性系：四组不稳定的重原子核，通过一系列α衰变和β衰变直至达到稳定的核为止。

It's the force that holds atomic nuclei together and even as we now know holds protons together in terms of their more basic building blocks, quarks and muons.

这是武力，认为原子核在一起，即使我们现在知道质子共同拥有在其更基本的构建模块，夸克和介子。

With the currently available technology and nuclear tracers, however, many challenges remain before clinical applications are possible.

尽管目前可用的技术和原子核追踪剂，在临床应用之前，仍有很多挑战。

Right up to the present day, all experimental data, on scales ranging from subnuclear to galactic, are successfully explained by these three theories.

而到目前为止，小至次原子核，大至星系，所有的实验数据，都能用这三大理论圆满地解释。

At the same time, the nucleus discharges negatrons to maintain the overall balance.

它在变为质子的同时，原子核一定会放出电子，保持整体平衡。

Our research indicates that the electronegativity of elements varied with the intensive electrostatic potential of atomic nucleus Vic and the quantity of electricity of atomic valence shell qcj.

研究表明，元素电负性XSc与原子核在原子边界面上的强度电势Vic和价层电子电量qcj成线性关系。

Our research indicates that the electronegativity of elements X(subscript Sc varied with the intensive electrostatic potential of atomic nucleus V and the quantity of electricity of atomic valence shell q.

研究表明，元素电负性X与原子核在原子边界面上的强度电势V和价层电子电量q成线性关系。

When the metal rods of cadmium were pushed all the way in, and stray neutrons that entered the pile were absorbed, and could not enter uranium—235 nuclei, and so there was no reaction at all.

当镉金属棒全部推入，进入反应堆的流动中子就被吸收，不能进入铀－－235原子核，因而完全没有反应。

"Specialized techniques include Raman spectroscopy, nuclear magnetic resonance, nuclear quadrupole resonance, dynamic reflectance spectroscopy, microwave and gamma ray spectroscopy, and electron spin resonance."

专门的光谱技术有拉曼光谱、核磁共振、原子核四极矩共振、动态反射光谱、微波和γ射线光谱，以及电子自旋共振。

An instrument for measuring a property of light, especially luminous intensity or flux.

辐射由一种放射性物质发出的辐射，包括α粒子、原子核、电子、和γ射线

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
