cirri-

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

5鳃表面都有前纤毛、侧纤毛和前侧纤毛。

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，仅在河蚬鳃表面前纤毛和前侧纤毛之间，观到一新纤毛结构——前触毛。

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

类似环日成一样，在高空卷云中，月光通过稀薄、具有六边冰晶时产生了幻月。
