If the film gets too thin, the diffuse charge clouds overlap and repel, just as two neutral atoms do when their electron clouds interact.
当一个薄膜变得太薄时,弥散的电荷云发生交叠并相互排斥,就好象电子云交叠时两个中性原子的行为一样。
Even in fair weather, a very small electric field is present in Earth's atmosphere. This field can charge airborne particles and the edges of clouds, Harrison said.
哈里森说,即使很好的天气情况下,地球大气层的电场依然存在。电场可以使空气中传播的粒子以及云端边缘带电。
Private clouds offer many of the same benefits that public clouds do with one major difference: the enterprise is in charge of setting up and maintaining the cloud.
私有云可提供公共云所提供的许多好处,一个主要不同点是:企业负责设置和维护云。
Private clouds offer many of the same benefits as the public clouds - the major distinction being that your organization is in charge of setting up and maintaining the cloud.
私有云具有许多与公共云相同的优点,主要差异在于您的组织负责创建和维护云。
The ancient Greek god Zeus was said to control lightning, but today we know lightning comes from a difference in electrical charge between clouds and the ground or among clouds.
据说,是古希腊神宙斯掌控着闪电,而如今我们知道是云朵和地面或云朵之间的不同电荷引发了闪电。
Therefore, electrons cannot be pictured as localized particles in space but rather should be thought of as" clouds" of negative charge spread out over the entire orbit.
因此电子不能描述为空间所处位置的微粒,只能认为负电荷占整个轨道扩散开来的“云”。
