frazil

After accumulation of frazil ices and crushed ices is formed, it will develop toward upper reach and also process slowly toward lower reach.

这冰花与碎冰显著聚积体形成后即可向上游发展，也能向下游缓慢。

Later that afternoon I went to another lecture, about ice, in all its varieties: frazil, grease, brash, shuga, pancake, white, drift, rafting and fast.

在那下午稍晚时候，我参加了另外一讲座，是有关冰，讲到了冰所有变种：结、溜、碎片、松软、扁平、白色、流动、漂流和坚固。

Ice jam flood: a lot of frazil ices and crushed ices gather under the covering ice, causing heading up of water level of upper reach.

冰塞洪水，大量冰花与碎冰在盖面冰下集聚，造成上游水位显著壅高现象。
