The roof abscission layer is the biggest security hidden danger in bolting support tunnel.───对于球果基部不能形成脱离层的针叶树，摇树机的作用不大，或者完全不起作用。

For conifers which do not form an abscission layer at the base of the cone, shakers have been partially or completely unsuccessful.───对于球果基部不能形成脱离层的针叶树，摇树机的作用不大，或者完全不起作用。

Roof abscission layer monitoring is one of important part of integrated monitoring in the full-anchor support roadway tunneling process.───顶板离层监测是全锚支护巷道掘进过程中综合监测的重要内容。

Tyloses are often found in injured tissue, older wood, and below an abscission layer, and can completely block the conducting vessel.───受损害的组织、衰老的木材和离层下方的位置常发现侵填体，这可以完全阻塞负责运输的导管系统。
