英汉例句

• When the comet approaches the sun, it begins to glow because the electron cloud is energized by the sun「s proton wind.

  当这颗彗星靠近太阳的时候它就开始发光因为电荷云层(electron cloud)被太阳的质子风(protonwind)激活。

• The method to determine the electric potential distribution in the electron cloud by measurements of the ion current is discussed.

  文中还讨论了通过测量离子电流确定电子云中电位分布的方法。

• So, what I」m showing in this picture here is just an electron cloud that you can see.

  你们可以看到我现在展示的这张图是，一个电子云。

• Fluorine is the most negative-electronic element, So negative charges gathered around fluorine atoms and electron cloud covered densely in polymers.

  氟是元素周期表中电负性最大的元素，因此聚合物中氟原子上负电荷比较集中，电子云密布。

• While the Bohr model does not correctly describe an atom, the Bohr radius keeps its physical meaning as a characteristic size of the electron cloud in a full quantum-mechanical description.

  尽管玻尔模型并没有正确地描述原子，玻尔半径还是保有了它的物理意义，代表着电子云大小的完全量子力学描述。

• The atom at the tip of the chain emitted electrons onto a surrounding phosphor screen, rendering an image of the electron cloud around the nucleus.

  碳链末端的原子发射电子到周围的磷光屏，得到原子核周围电子云的图像。

• The difference between bonded atom and the free one in state is that the overlap of electron cloud of bonded atoms in a molecule is considered.

  束缚原子不同于自由原子之处，是束缚原子考虑了在不同分子中电子云的不同重叠，将计算结果与实验及其它计算结果进行了比较。

• Most of the atom's volume consists of a cloud of electrons that have very small mass and negative charge. The electron cloud is bound to the nucleus by the attraction of opposite charges.

  原子核被弥散的电子云环绕，电子是带负电的几乎没有质量的粒子。由于正负电荷间的吸引而使带负电的电子受带正电的原子核约束。

• The chart of electron cloud can reveal the distance between each object and their clustering center.

  电子云图的优点是可以反映每个对象与相应聚类中心的距离。

• I can see many electron cloud suddenly vanish on the originally track, then jump to the higher energy level track.

  我可以看到很多电子云突然间在自己原本的轨道上消失，然后跃迁到更高能级的轨道上。
