A Study of Solar Rotation and Differential Rotation

The Sun has solar rotation;nevertheless, many evidences have suggested that different latitude of the Sun rotates in different speed, which is now known as differential rotation. This work calculates the solar rotation speeds near the equator and 30? in the northern hemisphere using Fixed-Point Arithmetic method. The calculated results show a greater speed at the equator than the speed at 30?, indicating that the speed decreases as the latitude becomes higher. .

Influence of lumbar disc degeneration on the efficacy of lumbar fixed-point rotation manipulation in sitting position:a finite element study

Objective：To investigate the influence of lumbar disc degeneration on the efficacy of lumbar fixed-point rotation manipulation in sitting position in treating lumbar intervertebral disc herniation（LIDH）.Methods：We simulated lumbar fixed-point rotation manipulation of sitting position using three finite element models including a normal model,a mild degeneration model and a moderate degeneration model of L3-5,in which the herniated disc was assumed at the left rear of L4 disc and the rotation manipulation was carried out on the right side.The displacement and stress at the left rear of L4 disc of the three models were analyzed.Results：When lumbar fixed-point rotation manipulation in sitting position was carried out,a displacement and stress were generated at the left rear of L4 intervertebral disc of the three models directing forward.The displacement and stress in degeneration models were less than those in the normal model,and the smallest values were found in the moderate degeneration model.From normal model to mild and then to the moderate degeneration model,the displacement decreased by 36% and 59%,and the stress decreased by 22.3% and 45.2%,respectively.Conclusion：The lumbar disc degeneration affects adversely the effectiveness of lumbar fixed-point rotation manipulation in sitting position in the treatment of LIDH.The severer the lumbar degeneration,the greater the influence.

目的观察颈2定点旋转复位法治疗颈源性枕大神经痛的疗效。方法选择112例颈源性枕大神经痛患者,将首次发病者57例作为首次发作组,1 a内反复发作3次以上者55例作为反复发作组。分别采用颈2定点旋转复位法手法治疗1个疗程,比较2组疗效。结果总治愈率为83.9%。首次发作组治愈率为94.7%,反复发作组治愈率为72.7%,2组治愈率比较有显著性差异(P<0.05)。结论采用颈2定点旋转复位法治疗颈源性枕大神经痛,可以定位解除枕大神经的压迫或刺激,对首次发作者疗效较好。

手法加正脊调盆法治疗膝关节骨性关节炎疗效观察

目的观察中医手法加正脊调盆法治疗膝关节骨性关节炎的临床效果。方法120例膝关节骨性关节炎患者随机分为两组,对照组予以单纯手法治疗;治疗组予以手法加正脊调盆法治疗。以临床症状改善情况及积分值进行疗效判断;病例随访1年进行复发率比较。结果治疗组总有效率为93.3%,对照组为85%,差异有统计学意义（P〈0.05）;随访后对照组复发率为21.6%,治疗组为7.1%,两组比较P〈0.05。结论中医手法加正脊调盆法治疗膝关节骨性关节炎的临床效果优于单纯手法治疗,1年后的复发率低于单纯手法治疗。

王国才治疗青少年特发性脊柱侧凸症临证思想及手法介绍

介绍王国才教授治疗青少年特发性脊柱侧凸症(AIS)临证思想及特色手法。王老认为AIS治疗要重视整体辨证,因人而宜;筋骨并重,调整脊柱力学平衡,重视调胸整肋,改善胸廓畸形;强调医者的功法练习,常针灸、推拿并用,注重补泻,并首创禅针法。王老总结出一整套治疗AIS的整脊手法,其中旋肋整胸法、旋脊法、提肩压胛法、仰卧位腰椎旋转扳法等皆为首创,临床疗效肯定。

Toric人工晶状体术后旋转的影响因素及处理原则

现代白内障手术已经转变成屈光性手术,因此安全有效地矫正散光是现代白内障手术的重要组成部分。Toric IOL(IOL)植入术因其高度的可预测性及安全性已经逐渐成为白内障术中矫正0.75D以上角膜规则散光的首选方式。Toric IOL需要植入在一个精准的轴位才能达到良好的散光矫正效果。Toric IOL错位的主要原因是术后旋转,这通常在术后不久发生。术后大幅度的旋转会降低Toric IOL的散光矫正效果,甚至在新的轴位上产生散光。术后IOL旋转的原因是多元化的,临床医生需要对此深入了解以最大幅度地减少旋转。大幅度旋转后的处理一般选择复位手术,手术时机的把握也尤为重要。本文就Toric IOL术后旋转的影响因素及处理原则进行综述。

琼东南海域水合物OBS资料成像处理关键技术

海底地震仪(OBS)资料同时具备纵波和转换横波的优势,但其接收站点少、接收间距大的特点导致其处理方式相对常规海洋地震资料而言具有极大的挑战.对本文主要针对于OBS资料处理的关键技术:利用直达波进行OBS重定位处理,保证后续处理的正确性;利用水检资料和陆检资料进行波场分离,获得上行波场和下行波场;利用下行波进行P波镜像叠前时间偏移处理;对转换横波利用欧拉重构进行重定向处理及极化旋转处理、进行转换横波叠前时间偏移处理.最终获得海底成像清楚、海底以下成像分辨率高、偏移归位准确的OBS纵剖面及相应的转换横波剖面.同时具备的纵、横波剖面利于解释专家对水合物成矿区域进行综合分析.
