螺旋塞

Another modern twist, rather pop, Neocork, in California's Nappa Valley offers synthetic solutions, plastic corks.

在加利福尼亚的纳帕谷，另一种相当流行的新式螺旋软木塞提供了综合的解决方案——塑料软木塞。

The pump consists of swirl nozzle ,valve cover,plug assemble and sand scratcher.

该泵采用了旋转接头、螺旋阀罩、柱塞总成、刮砂器于一体的多功能防砂结构，具有排而不卡和漏失量小的特点。

Some wineries are throwing away the cork and replacing them with screw-top caps.

一些葡萄酒酿造厂扔掉了软木塞，并用有螺旋盖的瓶盖进行了替换。

This model of semiconservative replication-conservative because each new molecule has one half of the former parent molecule-was later confirmed by the work of Meselson and Stahl.

这个DNA复制模型称为"半保留复制"，因为两个新的DNA双螺旋分子中各含有一条母链。此模型之后得到了梅塞尔森和斯塔尔的证实。

A cheese grater, a mandolin slicer, and a cork screw are also examples of products that

奶酪磨碎机，曼陀林切片机以及螺旋拔塞器也都是会造成较小伤害产品的例子

Most kitchens have a utility drawer filled with such necessary tools as can openers, corkscrews, spatulas, and so on.

多数厨房有一个公共抽屉充满这样必要的工具象开罐头用具，拔塞螺旋，小铲，等等。

There are many whimsical pasta shapes that do just that, fashioned after such things as shells, corkscrews, wagon wheels, and radiators.

有做， 塑造在如此事以后象壳、拔塞螺旋、无盖货车轮子，和幅射器的许多异想天开的面团形状。

Corkscrews. Bottle openers.

只有什么螺旋拔塞器，开瓶器。。

Diffraction by helices It may be shownthat the intensity distribution in the diffraction pattern of a series of points equally spaced along a helix is given by the squares of Bessel functions.

衍射螺旋这可能是显示的强度分布的衍射图样的一系列点同样距离的沿螺旋给予的平方贝塞尔函数。

Experimental results indicate that the B/A value greatly affects the internal Nusselt number and friction factor of the twisted tube because the parameters decrease with the increase of B/A and S/d values, more rapidly with the former, and that the Nusselt number and friction factor of the twisted oblate tube increase respectively by 30%~150% and 20%~50%, as compared with those of the smooth tube at the same Reynolds number and Prandtl number.

实验结果表明：高扭曲比螺旋扁管的管内努塞尔数和阻力系数均随B/A值和S/d值的增大而减小，但随B/A值的增加而减小得更快，B/A值对高扭曲比螺旋扁管的管内传热与流阻性能影响更大；在相同雷诺数和普朗特数下，高扭曲比螺旋扁管管内的努塞尔数为光滑管的1.3~2.5倍；阻力系数为光滑管的1.2~1.5倍。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
