摘要翻译：
我们研究了空间限制对作用在粒子上的推进扩散泳动力强度的影响，该粒子通过利用其环境的化学自由能来产生密度梯度。利用最近提出的由化学反应驱动的自推进装置的简单模型，我们证明了在存在限制壁的情况下，力显著增加。我们还表明，这种效应在二维系统中变得更加明显。

英文摘要：
We study the effect of spatial confinement on the strength of propulsive diffusiophoretic forces acting on a particle that generates density gradients by exploiting the chemical free energy of its environment. Using a recently proposed simple model of a self-propelling device driven by chemical reactions taking place on some parts of its surface, we demonstrate that the force significantly increases in the presence of confining walls. We also show that such effects become even more pronounced in two-dimensional systems.
