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。

While the experimental side force distribution over a slender body with a blunt ogive nose is basically consistent with the curve of the analogy predicted, and the characteristic points and half cycle of the experimental curve are basically constant with the roll angle changing 360°. But the local maximums in the curve are not the results as the analogy predicted, which is an important flow feature of 3-D slender body than that of 2-D cylinder.

而钝头拱形细长体在大迎角下的截面侧向力分布与脉冲起动横流比拟方法预测的侧向力曲线的形状是基本相同的，而且随着滚转角旋转360°，截面侧向力分布曲线的特征点和半周期基本保持不变，即它们都基本上不受滚转角变化的影响；但是截面侧向力分布曲线极值点形成的原因却是不同的，这是细长体绕流区别于二维圆柱绕流的一个重要特性。

And conclude that the impulsively started cross flow analogy is not suit precisely to predict the sectional side force distribution of slender body with a pointed ogive nose, because the pointed nose slender body exhibit an roll angle effects.

认为脉冲起动横流比拟方法不适用于预测尖头拱形细长体的侧向力分布特性，因为尖头拱形细长体具有明显的滚转角效应。

Nematodes are not insects, but slender, unsegmented roundworms.

线虫病不是昆虫， but slender， unsegmented roundworms（我猜大概是解释线虫属于线虫动物门，昆虫是节肢动物门）。

The salinity reduction on the leeward side of the round mound reached 50%, and was 60% for the leeward side of the slender mound. Therefore, salt reduction showed better performance compared with wind velocity reduction. The salinity observed at the wind gap decreased with the increasing of distance from wind gap, but between round and slender mounds, no significant difference was detected.

在减盐效果方面，圆形与细长形土堤背风面平均减盐效果达50%至60%，两者之减盐效果皆优於减风效果；再者，圆形与细长形土堤中间之风口处，盐分量随距离增加而递减，然而差异并不明显。
