根据零族元素性质的变化规律 ,运用线性回归方法 ,建立了 12个线性回归方程 ,利用这些方程对 118号元素的原子半径 (ratom)、沸点 (Tb .p .)、熔点 (Tm .p .)、蒸发热 (Hevapn)、临界温度 (Tc)、第一电离势 (I1st)、溶解度 (Sx)、极化率 (α)、电负性(X)以及形成分离气态离子所需能量 (Eion)进行了估计 ;对于零族除 118号元素以外的其它元素而言 ,预言结果与文献报道值之间的相对误差绝对值 (｜RE｜)小于 13.5 % According to the variation rule of the elements of the elements, 12 linear regression equations were established by using the linear regression method. Based on these equations, the atomic radius, boiling point (Tb .p.), Melting point (Tm. , Hevapn, Tc, I1st, Sx, P (α), electronegativity (X), and the energy required to form gaseous ions for separation (Eion ); For the other elements than the 118th element, the relative error absolute value (| RE |) between the predictive result and the reported value is less than 13.5%
