closed shell meaning in English
闭合壳层
闭壳层
封闭壳
满壳层
Examples
- All the alkali metals have a single s-electron outside a closed shell .
所有的碱金属都在闭合壳层之外有一单个S电子。 - All the alkali metals have a single s - electron outside a closed shell
所有的碱金属都在闭合壳层之外有一单个s电子。 - The most stable atoms , that is , the ones that take the most time to decay , contain “ magic numbers ” of protons and neutrons that produce complete , closed shells unable to accommodate any more protons and neutrons
许多稳定的原子就是那些需要很长时间才消亡的原子，它们都包含了完整而“数量微妙”的质子和中子以及一个封闭的核外电子壳，使原子本身不能够再容纳更多的质子和中子。 - The contribution to the giant resonances from the currents of vector mesons are also examined , it shows that currents of vector mesons play an important role in collective giant resonances . by studying the properties of collective multipole excitations of nuclei , a general conclusion is that those effective lagrangians recently developed can well describe not only the nuclear ground state properties of finite nuclei , stable and unstable ones up to the nuclei drip lines , but also the collective excited states and giant resoancnes in doubly closed shell nuclei
通过对核的电多极巨共振性质的研究，我们发现现有的这些非线性的有效相互作用不但能够很好地描述有限核的基态性质，包括球形和变形核以及远离稳定线核，而且对一些双满壳核的集体激发态和巨共振性质也能进行合理地解释，包括巨共振峰的位置和中心能量。 - The frame radiated noise is one of the major noise resources of rotary machines , especially for gear case which has close shell and vibrating screen which works in vibrating ways , the frame radiated noise energy account for more than 90 % of total sound energy . so if we could not successfully resolve the problem , the noise of rotary machines would never be effectively controlled
结构噪声是旋转机械的主要噪声源之一，尤其是对于如齿轮箱这类具有封闭壳体的机械和如振动筛这类以振动为主要工作方式的机械，结构振动辐射声能占总声能的比例甚至可以达到90 95 ，因此不解决结构噪声问题旋转机械噪声就不能得到有效的控制。
