The percolation threshold of electrically conductive fun ction was studied by mixing adhesive elements with conductive elements and then laminating with wood elements together to form wood-based composite panels.The results showed that the threshold values were about 8%～14%,and the spreading co n tent and filling content were correspondingly about 14%～25% and 12%～20%,respec tively.The uniformity of conductive function was better once the percolation phe nomena occurred.Additionally,some mechanism and numerical relationship should be further researched.%通过导电单元掺杂粘合单元并叠层复合木质单元研 究了导电功能木质复合板材的渗滤阈值。结果表明，形成渗滤效应时的阈值为8%～14%，对 应的导电单元施加量和填充量分别约为14%～25%和12%～20%；形成渗滤效应之后，导电功能 的均匀性较好。此外，相关机理和量化关系还有待于深入研究。
