n.螺旋形

Helicity is a good indicator for variations of wind field with altitude. 螺旋度可以作为观测雷达站上空风场随高度变化的一个敏感因子；

The wet potential vorticity and helicity are diagnosed and analyzed. 主要对湿位涡和螺旋度进行了诊断、分析。

This property, often called "helicity," serves to differentiate the neutrino from its antiparticle. 这种性质通常称为“螺旋性”，可以用来区分中微子和它的反粒子。

Actually the language teaching has its relation, is one kind “the helicity rise” the study. 其实语文的教学是有其联系性，是一种“螺旋性上升的”学习。

The dependence of the excitation energies of low-lying excited states on the diameters and helicity of CNT is studied. 也确认了奈米碳管的低激态态量与其半径及螺性的关系。
