frazil

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，造成游水位显著壅高现象。

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

这个冰花与碎冰显著聚积体形成后即可向游发展，也能向下游缓慢推移。

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

就在那个下午稍晚时候，我参加了另外一个讲座，是有关冰，讲到了冰所有变种：结块、滑溜、碎片、松软、扁平、白色、流、流和坚固。
