文摘:以密度泛函理论为框架,综述电负性和电负性均衡理论的发展及其在探讨各种分子性质时的应用。 - The proper atomic clustcr model is developed in the papel according to calculating results of quantuin chemiwt and the theory of sanderson electro - negativity the law of electron distribuing in brass material and the electto - negativity of brass - zinc are established
为进一步研究反应机理，本文采用适当的原子簇模型，通过量子化学计算及sanderson电负性分析对黄铜中的电子分布规律及铜锌电负性进行了探讨。 - The researching result is shown that an electron divided equally trend and an action of bond forming exist in brass atom and zinc atom in brass substtate . so , the electro - negativity equilibrium principle developed by sanderson et al , may be extend to the system such as brass under different conditions . the electro - negativity equilibrium was produced during the process from pure brass and pure zinc to brass - zinc alloy , and the difference of chemical properties between alloy and pure material is great
结果显示黄铜中铜锌原子间存在一定的电子“均分”趋势，使铜锌原子间存在一定的成键作用，可以将sanderson等人提出的“电负性均衡原理”有条件地推广到黄铜这类合金体系中，正是这种铜锌形成合金时所产生的电负性均衡，使得黄铜中的铜锌与单质状态下的铜锌相比，在化学性质上发生了差异，且增强了黄铜的稳定性，限制了黄铜中的锌在镀液中渗出。 - All analysis and simulations results indicate several methods improving the insulation recovery of spark gap switch : ( 1 ) using the gas with good thermal conductivity , such as h2 and sf6 ; ( 2 ) using the gas flow ; ( 3 ) utilizing the v / p cure ; ( 4 ) modifying the geometry and size of the electrode ; ( 5 ) using the gas with good electronegativity , such as sf6 . some experiments on the multi - pulse operation of high power spark gap switch are carried out . the insulation recoveries of switch without and with gas flow are both investigated
