The effects of tripping annulus on a pipe flow and a channel flow were compared and analysed . it indicated that the effect on both flow are mostly identical 全面比较了入口挡环对管流和渠道流中湍流发展过程的影响，发现两者在多方面均存在着一致性。
Annulus comparing grows rate , pointing to commonly is point to report period level and level of before one period than , show the phenomenon is chased period development speed 环比发展速度，一般指是指报告期水平与前一时期水平之比，表明现象逐期的发展速度。
This paper dealed with the annuli characteristics , age , growth , reproduction strategies and histology of the gonad development of spawning stocks for g . przewalskii 本文研究了青海湖裸鲤繁殖群体的年轮特征、年龄、生长、繁殖对策和性腺组织学。结果如下： 1
Based on the experiment of annulus - road made by chongqing road science institution of the ministry of transportation & communication , we introduce the bridge monitor system of its vibration in the paper 论文在交通部重庆公路科学研究所环道实验的基础上，对桥梁监测系统进行了分析。
Here , we will give an independent proof of the existence for inequality ( 2 . 1 . 3 ) , and by the way , give an estimate on the width of the bi - enclosing annulus of closed convex curves in the plane 3 )给出独立的存在性证明，并且还对平面闭凸曲线的bi - enclosing环的宽度给出了一个估计。
The effects of the different tripping size were not alike , 20 % tripping annulus was the best size for a pipe flow to obtain fully developed turbulence in the experiment . 8 不同尺寸的挡环对流动中心处相对湍流强度的影响不同，实验结果表明， 20挡环是形成充分发展圆管湍流的最佳尺寸。
The annulus generates a continuous catapsi effect within a 100 - foot radius of the wielder ( who is unaffected ) . the wielder gains a + 4 enhancement bonus to mental hardness “灭灵之环”持续产生以持用者为中心的100 ?半径的“抑能术”效果（持用者不受影响） 。持用者的精神硬度获得+ 4增强加值。
Lin yi annulus , step chinese popular musical circle formally 1993 , become in those days an a dark horse , also be chinese popular musical circle 10 years since one of prominent delegate figures 林依轮， 1993年正式踏入中国流行歌坛，成为当年的一匹黑马，也是中国流行歌坛十年以来杰出的代表人物之一。
3 . based on the wall equation and k - ? model , the variable c ? and the variable lm were used to improve the numerical simulation of pipe flow with the tripping annulus at the inlet 在壁函数和-模型的基础上，采用了变模型常数c _ ( l )和变混合长度l _ m的方法对入口处带有挡环的圆管湍流模拟计算进行了修正。
