1The axial evolution law on the structure and the aerodynamic characteristics of the asymmetric flows around slender bodies of revolution at incidences is summarized:whether the flow asymmetry is powerless or powerful,the flow always appears in the structure that lee-side vortices rise,and shed vortices form,and new lee-side vortices come into being alternately on opposite sides of a slender body of revolution axially from nose apex downstream to afterbody,and always induces the sectional side force of waving quasi-sinusoidally downstream axially.
1总结出细长旋成体有攻角非对称绕流流场结构和气动力特性的轴向演化规律：无论非对称性强弱，沿轴向从头部尖顶往后体，非对称绕流总是呈现为左、右两侧背涡交替从物面向上飘起、形成脱落涡、再衍生出新生背涡的流场结构，并诱导出沿轴向呈类似正弦曲线形式振荡分布的截面侧向力。

The research indicates there is a large left-lateral movement trend in the eastern China, which covers nearly a half of the area of Chinese mainland and affects the crustal movement in the entire eastern China and its adjacent areas. It is considered that the present-day coastline of China seas is just resulted from such a left-lateral movement, and Stype coastline will be more curved in the future.
研究表明：中国东部的地壳运动存在着一个大的左旋运动态势，其范围覆盖近一半的中国陆地面积，影响着中国整个东部和周边区域的地壳运动，中国东部现今的海岸线形态可能很大程度上归因于这种地壳运动，而且中国海岸线的"S"形曲线将会随着地壳运动变得更加弯曲。

There was a good correlation between Ptw,AVCtw,MVOtw,PTV,PUV,UntwR and age.2.Assessment of left ventricular twisting and untwisting of DCM patients19 DCM patients(range 18-80 yr,mean age 50.52±17.52 yr,2 females) and 21 age- and sex-matched normal controls(range18-80 yr,mean age 49.05±16.94 yr,5 females) were enrolled into this study.Then DCM patients were divided into two groups:E/A＜2 group and E/A＞2 group.The routine echo showed the left ventricle dilated and EF decreased.The results show that LV rotation degree, rotation velocity at baseline and apex were irregular changeable with the cardiac cycle;the rotation direction was clockwise at the base and counterclockwise at the apex,and are combined to yield a systolic counterclockwise twisting as seen from the apex,but the rotation at the basal and apex were the same direction in some patients.
扩心病患者左室扭转及解旋特征的研究选择扩张型心肌病(Dilated Cardiomyopathy，DCM)组患者19例(男性17例，女性2例，年龄18～82岁，平均50.52±17.52岁)，健康体检者21例(男性16例，女性5例，年龄18～80岁，平均49.05±16.94岁)作为对照组，扩心病患者按照E/A分为E/A＜2、E/A＞2两个亚组，结果显示：常规超声显示DCM组LVDd值增大，EF值减小；DCM患者左室心底部与心尖部心肌旋转角度、旋转速度随心动周期变化曲线明显紊乱；与正常组比较，DCM患者左室整体扭转角度和速度分别为(6.49±1.82)°、(67.84±15.60)°/s，较正常人显著减低P＜0.01左室舒张末及收缩末扭转角度DCM患者较正常人显著减低(P＜0.01，左室舒张末及收缩末时间在DCM-E/A＞2组较正常人及DCM-E/A＜2组显著缩短P＜0.01DCM患者左室解旋速度较正常人亦显著减低(P＜0.01，左室功能轻中度减低(DCM-E/A＜2)患者解旋率[(0.29±0.07)%]较正常人[(0.42±0.11)%]明显减低，但当左室功能重度减低(DCM-E/A＞2)时左室解旋率[(0.63±0.35)%]较正常人反而增加；左室整体扭转角度、舒张末扭转角度、收缩末扭转角度、解旋与左室射血分数未见明显相关性。3。
