- Once an antiproton and positron have joined forces, the resulting antihydrogen atom is electrically neutral and thus no longer caged by the electrical fields in the trap. 一旦一个反质子和正电子具有了结合的力量,产生的反氢原子是中性的,结果在线圈中不再受电场束缚。
- When the total number of protons equals the total number of electrons, the body as a whole is electrically neutral. 当质子总数等于电子的总数时,这个物体就整体来说是电中性的。
- As a result, the disks are composed largely of electrically neutral dust and gas rather than ionized plasma. 结果导致其主要构成物质为电中性的尘埃和气体,而非离子化的电浆。
- If an atom contains three protons, it must have three electrons to be electrically neutral. 如果一个原子含有三个质子,这个原子必然有三个电子,使之不带电荷。(重复“原子”
- Neutrons, being electrically neutral particles, do not produce ionization or excitation directly in their passage through matter. 中子是中性不带电的粒子,当它通过物体时并不直接产生电离或激发作用。
- In ionic solutions, the condition of electrical neutrality provides such an additional relation too. 在离子溶液中,电中性条件亦提供了这种附加关系式。
- It has been shown throughthe experiment that the charges of the nucleus and electrons are equal so that the atom is electrically neutral. 实验表明原子核和电子的带电量相等,因此原子成电中性。
- An electrically neutral excited state of an insulator or semiconductor, often regarded as a bound state of an electron and a hole. 激子由于吸收光子在固体中产生的可移动的束缚的电子-空子对
- Since all compounds are electrically neutral, there also must be a species in the oxidation-reduction reactions that gains electrons. 因为所有的化合物都是电中性的,因此在氧化还原反应中某种物质一定获得了电子。
- The other side of the hairpin carries a collection of negative charges, so that the whole caboodle is electrically neutral. 发夹的另一端携带者一些负电荷。这样整个东西就呈电中性了。
- Neutrinos are electrically neutral, virtually mass-less elementary particles that can pass through miles of lead unhindered. 它们可以穿过数英里的距离而不和任何物质相互作用。
- The two Higgs fields give rise to five species of Higgs boson: three that are electrically neutral and two that are charged. SSM中的两个希格斯场会导致五种希格斯玻色子:三个是不带电的中性粒子,两个则是带电粒子。
- Once an antiproton and positron have joined forces, the resulting antihydrogen atom is electrically neutral and thus no longer caged by the electrical fields in the trap. "The atom drifts to where it wants to go," said Dr. 一旦一个反质子和正电子具有了结合的力量,产生的反氢原子是中性的,结果在线圈中不再受电场束缚。
- An electrically neutral,highly ionized gas composed of ions,electrons,and neutral particles. It is a phase of matter distinct from solids,liquids,and normal gases. 等离子体由离子、电子和不带电的粒子组成的电中性的、高度离子化的气体,它是与固体、液体和正常气体相区别的一种物质状态。
- Be he a civil engineer or an electrical engineer? 他是土木工程师还是电气工程师?
- Plasma: an electrically neutral, highly ionized gas composed of ions, electrons, and neutral particles. It is a phase of matter distinct from solids, liquids, and normal gases. 等离子体,由离子、电子和不带电的粒子组成的电中性的、高度离子化的气体。
- Neutrino is an electrically neutral subatomic particle, which has very little interaction with any other matters. Hence, the star will be transparent to them. 中微子是亚原子粒子,它们差不多不会和任何物质产生反应,所以恒星对它们来说是透明的。
