Ｔ８荧光灯是一种高效节能照明光源，但在环境温度过低、放电电流太小时，它常常会出现条纹放电，对照明造成很大干扰．研究条纹放电的成因和特性是解决这一问题的先决条件．首先从放电等离子体的基本方程出发，求得非均匀等离子体正柱中的色散关系；由此通过计算得到条纹放电形成条件，条纹放电的频率、相速和时间增长率等主要参数．对Ｔ８荧光灯中的条纹放电进行实验研究，并测定其主要参数，发现与理论计算符合较好．
T8 fluorescent lamp is a highly efficient and energy-saving lighting source, but when the ambient temperature is too low, the discharge current is too small, it will often appear stripe discharge, causing great interference to the lighting. Studying the causes and characteristics of stripe discharge is a prerequisite for solving this problem. First of all, based on the basic equation of discharge plasma, the dispersion relation in the non-uniform plasma positive column is obtained. The formation parameters of stripe discharge, the frequency of stripe discharge, the phase velocity and the time growth rate are calculated. The stripe discharge in T8 fluorescent lamp was studied experimentally, and its main parameters were measured. It was found that it was in good agreement with the theoretical calculation.
