原子核的

In the early 1950s American scientist s produced the hydrogen bomb by inducing fusion reactions in a mixture of the hydrogen isotopes deuterium and tritium, forming a heavier helium nucleus.

1950年代，美国科学家在氢的同位素氘和氚的混合物中引导聚变反应生成较重的氦原子核，从而制造出了氢弹。

The theoretical prediction of large energy gap exists near the neutron number~44 and proton number~38-40 are also compared and discussed.

许多理论预测在中子数N~44，而质子数Z~38-40 附近，存在大的能隙，而我们研究的几个原子核，其核子数恰好位在此能隙附近，所以文中也针对此变形位障所预测的幻数加以讨论。

Matter is composed of molecules, which are composedof atoms, which are composed of atomic nuclei and electrons.

物质是由分子组成的，分子是由原子组成的，原子是由原子核和电子组成的。

Matter is composed of molecules, which are composed of atoms, which are composed of atomic nuclei and electrons.

物质是由分子组成的，分子是由原子组成的，原子是由原子核和电子组成的。

The nucleus carries an amount of positive electricity equal to the negative electricity carried by all the flying electrons.

原子核带有一定量的正电，与全部飞行中的电子所带的负电相等。

Drift-II is more ambitious. If it works, it will be able to track such a recoiling nucleus through a device filled with gas.

而Drift-II的目标更加远大，如果可能，它可以在充满某种气体的装置中跟踪碰撞后的原子核。

A view popular in physics is to start with uncharged electrons and cores, which are therefore both free and plane waves and can have any energy, and then fade in the charge.

物理学中流行的方法是从不带电的电子和原子核出发，因为它们是自由的平面波，可以具有任意能量，并在带电后衰减。

After a consideration of the movement revision of the atomic nucleus,by using a variation wave function of a parameter k to discuss the ground state energy for the B+++ ion to carry on the variation computation..

考虑对原子核运动的修正后，通过使用一个带松弛坐标参数k的变分波函数对B+++离子的非相论基态能量进行了变分计算。

EMHYDR HR oils have excellent oxidation stability and demulsibility, enabling ready separation of entrained water and giving long life without formation of harmful sludge.

守恒定律使我们能够就可得出有关原子稳定性的具有深远意义的结论，而不需要对原子核内起作用的力作任何假设。

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。

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％。
