原子核的

The atomic number represents the number of nuclear protons or, in the undisturbed state, the number of extranuclear electrons

原子序数表示原子核内质子的数目，也是在未被干扰的状态下核外的电子数。收藏反馈

The study of diatomic molecular potential energy function is the basic problem because diatomic potentials depend on only a single variable, the interatomic distance.

由于双原子分子的势能仅是原子核间距的函数，因此双原子分子势能函数是势能函数研究的基础问题。

At present, time-dependent quantum wave packet approach has emerged as a powerful computational tool for studying quantum reaction dynamics of triatomic and tetraatomic systems.

采用的量子力学方法能够完全从量子力学基本原理出发，真实而完全的反映原子核在势能面上的运动。

This conclusion is consistent with the idea that all atomic nuclear are built wholly of neutrons and protons.

这个结论与如下的思想是一致的：所有的原子核全部由中子和质子组成。

With the same number of protons, all nuclei of a given element may have different numbers of neutrons.

译：虽然某个元素的所有原子核都含有相同数目的质子，但它们含有的中子数可以不同。

Although all nuclei of a given element contain the same number of protons, they may have different numbers of neutrons.

虽然，给定元素的所有原子核都含有相同数目的质子，但它们的中子数可以不同。

"It has many uses-in dental and industrial amalgams, as a catalyst, in electrical and measuring apparatus and instruments (e.g., thermometer s), as the cathode in electrolytic cells, in mercury-vapour lamps, and as a coolant and neutron absorber in nuclear power plants."

汞有许多用途，如牙医和工业上用的汞齐、催化剂，电学和测量装置，以及仪器中、电解池中的阴极，汞蒸汽灯，以及原子核发电厂中的冷却剂和中子吸收剂。

Bosons include mesons, nuclei of even mass number, and the particles required to embody the fields of quantum field theory.

玻色子包括介子、偶质量数的原子核以及体现量子场论中的场所需要的粒子。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.
