Vibration frequencies of Si-H and Si-D bonds and the electronegativity of silyl groups

Summary A simple empirical relation is put forward for relating the vibration frequencies of Si-H and Si-D and also Ge-H and Ge-D bonds to the electronegativities of silyl and germyl groups.     

相对论性核碰撞中φ介子增强

用强子和弦级联模型LUCIAE系统地研究了相对论性p+p和Pb+Pb碰撞中φ介子产生.在模型框架内实验测得的158AGeV/cPb+Pb碰撞中φ介子产额相对于同能量p+p碰撞的增强现象,依赖于弦发射胶子的集体效应和奇异夸克压低约化两机制,在一定程度内能得到解释.     

在RHIC的极限碎裂和Ф介子产生(英文)

利用强子和串级联模型LUCIAE研究了PHOBOS的极限碎裂等以及在PHIC进行的Au +Au碰撞中带电粒子多重性的经验标度规律 .对介子的产生机制也通过与带电粒子多重性的比较进行类似的研究 .结果似乎表明在串级碎裂模型中带电粒子和介子有共同的产生机制 .还讨论了PHOBOS经验标度规律的模型依赖性 .

Gain and power characteristics of an electron-beam controlled discharge TEA CO2-laser

Gain coefficients and power characteristics of an electron-beam controlled discharge TEA CO₂-laser have been investigated based on computer simulations of the gain kinetic molecular processes in the pumped medium and experimental measurements of the electrical and laser properties of the system. Optimal operation conditions are discussed.
