A theory is developed that is suitable for describing a two-species thermalization process in a plasma with parameters suitable for recombination to take place. Recombining plasmas have recently been produced using positrons and antiprotons [M. Amoretti et al., Nature (London) 419, 456 (2002); G. Gabrielse et al., Phys. Rev. Lett. 89, 213401 (2002)]. The theory is not restricted to large Coulomb logarithm values, and correspondence with prior theory is shown in the limit of large Coulomb logarithm values. The theory applies for two plasma species, each having a Maxwellian velocity distribution and being weakly correlated.
我们提出了一种理论，该理论适用于描述等离子体中的双物种热化过程，其参数适合发生复合。最近利用正电子和反质子产生了复合等离子体[M. 阿莫雷蒂等人，《自然》（伦敦）419, 456 (2002)；G. 加布里埃尔塞等人，《物理评论快报》89, 213401 (2002)]。该理论不限于大库仑对数的值，并且在大库仑对数的极限情况下显示出与先前理论的一致性。该理论适用于两种等离子体物种，每种物种都具有麦克斯韦速度分布且相关性较弱。
