Effects of previous lateral ankle sprain and taping on the latency of the peroneus longus

The latency of the peroneus longus may be a key factor in the prevention of lateral ankle sprains (LASs). In addition, ankle taping is often applied to help prevent LASs. The purpose of this study was to determine the effects of a previous LAS and ankle taping on the latency of the peroneus longus after an inversion perturbation. Twenty-six participants, including 13 participants with no previous history of a LAS and 13 participants with a history of a single LAS completed the testing. Ankle taping was applied in a closed basket weave technique on one of the two testing days. The latency of the peroneus longus was determined by the onset of muscle activity exceeding 10 SD from baseline activity, after initiation of the 25° inversion perturbation. A significant main effect (p < 0.05) was present for the ankle support condition, with ankle taping causing a significant reduction in latency of the peroneus longus (65.04 ± 10.81 to 57.70 ± 9.39 ms). There was no difference (p>0.05) in latency between the injury groups. Ankle taping, immediately after application, reduces the latency of the peroneus longus among participants with and without a history of a LAS.

多重网格法在地球物理正反演应用研究中的进展

现阶段地球物理三维勘探面临越来越复杂的问题,其要求更精细的三维网格剖分,现有的一些方法随着网格节点的增加其收敛速度相应减慢。对于应用中更复杂实际模型、更细密网格剖分以及更快收敛速度要求,难于有进一步提高。要有所突破,需借助计算数学最新进展,引入新的高效算法。多重网格法是近二十年迅速发展的一种求解微分方程近乎最优的新算法。本文首先简单介绍了多重网格法基本原理和运算格式,着重介绍了当前国内外多重网格法在地球物理正反演中的应用成果和发展现状。此外,对多重网格法在地球物理正反演中的应用前景及发展趋势进行了展望。

论我国民事举证责任分配的若干问题

举证责任的分配要解决的问题是在争议的事实处于真伪不明时由何方承担不利的诉讼后果。根据法律要件分类说和诚信原则及公平原则,我国民事诉讼中分配举证责任实行"谁主张,谁举证"的一般原则和举证责任倒置的例外原则、补充原则。我国对举证责任分配原则规定不合理的地方有待立法和司法进一步完善。     

论维吾尔语口语里的易位现象

从语用学和话语角度对维吾尔语口语里的易位现象进行了探讨,并将口语里的易位现象和书面语的正常语序进行比较,最终得出了易位并不仅仅是单一的语法问题和纯粹的修辞现象,而是一种语用现象的结论。
