Stars are born in these interstellar clouds, which are located in the spiral arms of our milky way galaxy 在我们银河系里，恒星就是在位于银河系旋臂上的这种星际气云中产生的。
Even slight spiraling motion in a square pipe increases the tendency of particles to be maintained in suspension . 水流在方管中稍有一些螺旋运动，将增加泥沙悬浮在水中的作用。
The latter half of the century was getting rather ashamed of the towers with their circular or spiral paintings . 到了这个世纪的后半叶人们开始对塔上围绕的或者盘旋的绘画觉得惭愧。
Two general categories of dislocations are spiral and line(edge), the terms being aptly descriptive of their shape . 位错一般分为两种形式，螺形和线形（刃型）位错。其术语恰当地表征了它们的形状。
Chiu and seman(1971)studied the head loss of flows transporting sediment in circular and square pipes with spiraling motion . 邱和思门（1971）研究了在圆管和方形管中输沙时具有螺旋运动的水流的水头损失问题。
A letter may be compressed into a thin spiral roll, not differing much in shape or bulk from a large knitting-needle, and in this from it might be inserted into the rung of a chair, for example . 一封信可以缩成一个小纸卷，同一根粗的织绒线针的形状大小差不多，可以把这样的信塞到，譬如说，椅子的横档里。
