longitudinal extent

基本解释

Longitudinal uniformity is decided to a great extent by weighting balance feeding fiber current and transverse uniformity is closely relating to air transverse distribution.
纵向均匀度在很大程度上取决于成网机定量喂给的纤维流，而横向均匀度还与气流横向分布密切相关。
Results The X ray plain film of GD had characteristic change. The extent of bone involvement demonstrated could be depicted in longitudinal direction and the changes of marrow involvement on MRI.
结果本病的X线平片有特征性改变，MRI既能显示骨骼病变纵向累及范围，又能观察骨髓内部受累的变化。
The effects of RF radiation on longitudinal and transverse relaxation rates are negligible, while the RF radiation depresses cross-relaxation rate to some extent.
射频场的照射对纵向与横向弛豫速率的影响甚微，可以忽略，而交叉弛豫速率在射频场的照射下则有一定程度的降低。
