Periodic System of Atoms in Biquaternionic Representation

Private monochromatic solutions of the free-field equation of electro-gravimagnetic charges and currents are constructed in the differential algebra of biquaternions, which describe elementary particles as standing electro-gravimagnetic waves. The two classes of solutions of this biquaternionic wave equation have been investigated, generated by scalar potentials (pulsars) and vectorial potentials (spinors). Their asymptotic properties are considered, on the base of which they are classified into heavy (boson) and light (lepton) elementary particles. The biquaternion representation of the hydrogen atom is given. The periodic system of elements is produced, which is built on the principle of the musical structure of a simple gamma.

基于EMTP的高压直流输电线路雷电过电压研究

为了更准确地评估高压直流输电线路的耐雷水平以及雷击跳闸的特点,建立了高压直流输电线路的雷电过电压仿真模型,研究了杆塔的多波阻抗模型,计算了反击情况下和绕击情况下的耐雷水平,并分别利用规程法和电气几何模型法(EGM法)分析了线路的反击跳闸率和绕击跳闸率。研究结果表明反击耐雷水平较高,降低电阻对于提高线路耐雷水平的提高作用不大,绕击耐雷水平较低,且坡度越大,绕击闪络率越高。因此,线路立塔时应当避免在地形坡度较大的地方立塔,并且保证接地电阻在7Ω左右即可。
