abscission layer

The features of overburden strata movement are thick strata, multi-stages, slow development, synchronously collapse of multi-rock, leading a big abscission layer space, which is easy to connect to pre-existing fracture, forming ultra-high guide water flowing fractured zone.

覆岩运动为厚岩层，多阶段、慢发展，多岩层的同步垮落，导致离层空间大，容易沟通原生裂隙，形成超高导水裂隙带。

to do the measure abscission layer grouting in site, the first step is to make clear the developmental rule of abscission layer.

要进行采场覆岩离层注浆等技术措施，首先必须弄清离层的发展规律。

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。

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。
