加强无线电管理,日常监督检查势在必行

随着社会经济的迅速发展,无线电通信事业取得了很大进步,无线电通信广泛应用于各行各业,在经济发展、社会进步中发挥了重要的作用.但目前一些单位和个人无视国家有关频率管理和无线电设备管理的有关法规,擅自占用频率和非法设台情况比较严重,极大地损害了电磁环境和秩序,干扰了航空导航、公安、消防、护林防火、“三防”等重要通信业务,对无线电通信的可持续性发展造成了极大隐患,加强无线电管理日常监督检查势在必行.     

Instability due to Viscosity Stratification Downstream of a Centerline Injector

A common injector geometry upstream of a static mixer is the centerline injector. A flow instability can arise due to viscosity differences between the injected core‐flow and the outer co‐flow. This instability can adversely affect the effectiveness of the mixing operation. An experimental investigation of miscible viscosity‐stratified flow in a circular geometry was performed using Laser Induced Fluorescence (LIF) and Particle Image Velocimetry (PIV). The experimental results for the stable region agree with the analytical results. The unstable region exhibits different modes depending on the viscosity ratio, volume flux ratio, and Reynolds number. The modes include wavy core‐flow with fissures and wavy core‐flow with core breakup. The time‐averaged experiment velocity profiles for the unstable core indicate a broadening of the jet at the centerline, which is consistent with the LIF visualization.     

Fluorescence spectra of ARE2I5 and AREI3 in the solid state (A ≡ K, Rb, Cs, Ti; RE ≡ Sm, Eu)

The fluorescence spectra of ARE₂I₅(s) and AREI₃(s) (A ≡ K, Rb, Cs, Tl; RE ≡ Sm₁ Eu) have been studied systematically. The regular shift of the central wavelengths is discussed in a preliminary manner on the basis of crystal lattice field and covalence effects.
