Objective To compare the outcome of the vitrification using cryotop to the slow-freezing method for human cleaved embryos cryopreservation.
目的：比较载杆玻璃化冷冻法与程序冷冻法对人早期胚胎冷冻复苏的效果。
On the other hand, slow freezing can increase concentration shifts of components.
另一方面缓慢冷冻会造成产品组分的浓度上升。
The results show that there are three freezing stages by slow freezing, but the three freezing stages are not obvious by liquid nitrogen flash freezer.
结果表明：对黑牛肝菌进行缓慢冻结时，出现了明显的冻结三阶段现象，而在液氮速冻时此三阶段不明显；
The results show that there are obvious three freezing stages by slow freezing, but the three freezing stages are not obvious by liquid nitrogen flash freezer.
结果表明对白灵菇进行缓慢冻结时，有明显的冻结三阶段现象出现，而在液氮速冻时此三阶段不明显；
For example, slow freezing leads to the formation of larger ice crystals. This results in relatively large voids, which aid in the escape of water vapor during sublimation.
例如，缓慢冷冻造成较大的冰晶排列，造成冰晶升华时有较大的逃逸通道。
The tissues were randomly allocated to fresh, vitrification and conventional slow freezing groups.
组织被随机分配到新鲜组、玻璃化冷冻组和慢速冷冻组。
Then, the PGCs were froze respectively in six kinds of freezing medias under slow speed cryopreservation process and vitrification process.
以常规的慢速冷冻法为对照，研究了玻璃化冷冻法保存绵羊体外受精囊胚的效果。
The success of this method depends on the cells used, the selection of preserving agent and slow freezing as well as …
成败的重要因素在于选择好冻存用细胞，并掌握好冻存时缓慢降温和复苏时急速融化的速度。

Analysis indicates that the freezing-thawing is most important to failure of microstructure of soil; the second is slow-soaking.
分析表明冻融对土的微结构破坏最为严重，其次是慢浸。
Injection speed may be too slow causing freezing before mold is filled.
