［摘 要］ 目的：验证经络气道，阐明经络实质。方法：根据古典经络文献的有关论述，用多种实验研究验证经络气道有什么样的物质结构、功能和特征。结果：经络气道，有多种物质、宏观形态、经络路线、外部框架的间隙结构；有卫气运行、循经感传、血管变化、淋巴免疫的间隙功能；有低阻良导、双向运行、阻滞疏通、气道相通的间隙特征。结论：卫气营血的气血通道是广义经络，循经感传的卫气通道是狭义经络，经络实质是液气运行的间隙通道。

［abstract］ purpose to test and verify qi-passage of meridians and
collaterals, and clarify essence of meridians and collaterals. methods
substance structures, functions and characteristics of qi-passage of meridians
and collaterals were studied by many experiments based on classical literature.
results in qi-passage of meridians and collaterals there are many kinds of
substance, macroscopic form, channel lines, space structures of external frame;
and it also has interstitial functions of wei-qi moving, propagated sensation
along meridians, changes of blood vessels, and lymph and immunity, and it is
of interstitial characteristics of low electric resistance and good conduction,
bi-directional motion, removing obstruction and qi-passage communication with......
