与外部电源接触的等离子体，特别是与高速电子专门相互作用的源，表现出与接近热平衡的孤立等离子体不同的传输特性，例如导电性。即使当驱动等离子体中的大部分粒子接近热平衡时也是如此。为了描述驱动等离子体，我们推导了非齐次、线性化、动态玻尔兹曼方程的伴随方程。然后可以生成各种血浆反应的格林函数。可以修改 Chapman-Enskog [非均匀气体数学理论，第 3 版，（剑桥大学，剑桥，马萨诸塞州，1970 年）] 展开式，以便合并此处导出的响应函数。
A plasma in contact with an external source of power, especially a source that interacts specifically with highvelocity electrons, exhibits transport properties, such as conductivity, different from those of an isolated plasma near thermal equilibrium. This is true even when the bulk of the particles in the driven plasma is near thermal equilibrium. To describe the driven plasma, we derive an adjoint equation to the inhomogeneous, linearized, dynamic Boltzmann equation. The Green’s functions for a variety of plasma responses can then be generated. It is possible to modify the Chapman–Enskog [Mathematical Theory of Nonuniform Gases, 3rd ed., (Cambridge U.P., Cambridge, MA, 1970)] expansion in order to incorporate the response functions derived here.
