The lesion was very uncommon. The etiology may be a focal inflammatory response around the feeding arteries in the perineurium. The results of surgical treatment were good.

非创伤性桡神经麻痹伴神经多段束带样病变临床罕见，其病因可能是神经外膜、束膜内的血管炎；手术治疗效果良好。

Pathological examination showed the obvious edema in myelin sheath,axons and perineurium in 2 w group,and disintegrated myelin sheath,degenerated axons and hyperplastic fibrous connective tissues in the other model groups.

病理学观察：卡压2周组神经束内髓鞘、轴索和神经束膜纤维出现明显水肿，余卡压组可见髓鞘崩解、轴索变性，纤维结缔组织增生逐渐明显。

The study also investigates two types of planform modifications: 1. tapered vanes; 2. forward-swept and aft-swept vanes. The results show that with the same surface areas, forward-swept vanes and tapered vanes with constant height and larger length are able to improve the function on sediment control.

本研究同时探讨板顶束缩及板顶前后倾两种板形的改变，结果显示在固定面积的情况下，板高固定与板长改变的板顶束缩及板顶前倾两种形状的改变可增进潜板的效能，在决定潜板形状时，可参照二者的变化加以评估。
