摘要:

在本工作中,在发现等离子体中带电粒子的平均势能的问题中,基于对一些特殊附加条件的考虑或缺乏对物理系统(电解质、尘埃等离子体、等离子体)的分类。这里所考虑的系统,以及其他在附加条件下被描述的系统,被视为“封闭”型系统,而那些条件完全被忽略的系统,则被视为“开放”型系统。在我们以前的调查中,一个和两个组件系统进行了检查。本文首次选择了具有两种不同正电荷离子的完全电离电子-离子等离子体作为研究对象,其中包括非理想性较高的等离子体。对于这样的等离子体,一个新的描述静电屏蔽的自洽模型方法被发展,它包括了所有必要的附加条件。通过这种方法,诸如电子-离子和离子-离子关联等极其重要的现象被包括在所使用的模型中。所考虑的等离子体在一个广泛的区域的电子密度和温度的特性进行了计算。所有得到的结果,包括与系统的“开放”型的比较进行了具体讨论。

英文摘要:

Within the problem of the finding of the mean potential energy of the charged particle in the plasma in this work a classification of physical systems (electrolytes, dusty plasmas, plasmas) is made based on consideration, or lack thereof, of a few special additional conditions. The system considered here, as well as other systems which are described with those additional conditions imposed are treated as the systems of the "closed" type, while the systems where those conditions are fully neglected - as being of the "open" type. In the our previous investigation one- and two component systems were examined. Here, as the object of investigation fully ionized electron-ion plasma with positive charged ions of two different kinds, including the plasmas of higher non-ideality, is chosen for the first time. For such plasma a new self-consistent model method of describing electrostatic screening is developed which includes all the necessary additional conditions. By this method such extremely significant phenomena as electron-ion and ion-ion correlations are included in the used model. The characteristics of the considered plasmas in a wide region of electron densities and temperatures are calculated. All the obtained results, including a comparison with systems of the "open" type are specifically discussed.
