标题： Pulsar death line revisited -- I. Almost vacuum gap

摘要： 本文是专门用于详细分析射电脉冲星死亡线系列论文的第一篇，在文中我们研究了在足够长的脉冲星周期 P 下产生次级粒子的可能性。为此，我们重新考虑了在磁极帽区域内部间隙内生成次级等离子体所需的电势降。 我们的研究使得能够进一步细化次级等离子体产生的条件，例如次级粒子的多重性和它们的空间分布。 我们的研究还使得能够进一步定量分析次级等离子体产生的可能性与所有参数（包括磁轴相对于旋转轴的倾斜角、极帽大小以及磁场几何形状）之间的依赖关系。 显示英文摘要

摘要： In this paper, which is the first in a series of papers devoted to a detailed analysis of the death line of radio pulsars, we consider a possibility of producing secondary particles at a sufficiently long pulsar period P. To this end, we reconsidered the potential drop necessary for secondary plasma generation in the inner gap over magnetic polar caps. Our research made it possible to refine the conditions for generating secondary plasma, such as the multiplicity of the production of secondary particles and their spatial distribution. Our research also made it possible to further quantitatively analyse the dependence of the possibility of secondary plasma generation on all parameters, including the inclination angle of the magnetic axis to the rotation axis, the polar cap size and the magnetic field geometry.
