cirri

The results show that the gill surface of all five species have frontal cilia,lateral cilia and laterofrontal cirri.

这5蚌的鳃表面都有前、和前。

In addition,a new structure,frontal cirrus between the frontal cilia and laterofrontal cirri,is found only on the gill surface of Corbicula fluminea.

此外，仅在河蚬鳃表面前和前之间，观察到一新的结构——前触。

Analogous to a sundog or parhelion, the paraselene is produced by moonlight shining through thin, hexagonal-shaped ice crystals in high cirrus clouds.

类似环日的形成一样，在高空卷云中，月光通过稀薄、有边形状的冰晶时产生了幻月。
