The gradient of permeability along the capillaries of voluntary muscle and the capillaries and venules of skin exists independently of the hydrostatic conditions, though influenced by them. Its presence cannot be explained by a graded tonic contraction of the capillaries. The evidence,-like that of previous papers,-points to local differences in the barrier offered by the wall of these vessels as responsible for the gradient.
在随意肌的毛细血管和皮肤的毛细血管及小静脉中，渗透梯度的存在独立于流体静压状态，尽管会受到其影响。这种梯度的存在不能用毛细血管的紧张性节律性收缩来解释。与之前的论文一样，这些证据表明，这些血管壁的屏障所产生的局部差异是导致这种梯度的原因。
