freezing speed meaning in Chinese
冻结速度
Examples
- Apply ecologically water - cooling type freezing system with quick freezing speed and good result . the frozen temperature may reach minus 30 celsius degrees
采用水冷式冷冻系统,制冷速度快效果好,冷冻温度30 。 - Apply ecologically water - cooling type freezing system with quick freezing speed and good result . the frozen temperature may reach minus 30 celsius degrees
采用环保水冷式冷冻系统,制冷速度快效果好,冷冻温度30 。 - The slity soil frost ratio can be predicted through the input parameter of water content , density and freezing speed and the frost ratio is used in railway construction
由含水量、密度和冻结速率三个基本输入参数,预测粉质土的冻胀率,进而分析对铁路工程建设的影响。 - The primary results showed : using m199 as diluents containing 20 % bovine serum , it is better to freeze the cells slowly freezing at fist then increase freezing speed ( for example , from 0 to - 6 freezing speed is about - 0 . 05 a minute , from - 6 to - 40 , freezing speed is about - 0 . 5 a minute ) , studies on effect of various concentration of dmso demonstrate that about 12 . 5 % dmso gave the highest post - thaw percentage of viable cells . the concentration of bovine serum had no different effect on the percentage of the viable embryo cells of misgurnus auguillicaudatus . the embryo cells derived 6 from the later stage of blastula offish is more resistant to the cryogen than the cells of early stage of blastula . the cells preserved in liquid nitrogen at - 196 were thawed and cultivated , a few cells were found adhere to the surface of culture vessel when the percentage of viable cell was more than 30 % . the cells in only two culture vessels were found to proliferated and gave rise to many small morphologically undifferentiated cells
研究初步表明:以细胞培养液m199 (含2既的小牛血清,常规量双抗)为冻存稀释液对泥鳅胚胎细胞冷冻保存宜采取先慢后快的方式(例如,从0一一6 ,冻存速度为一0 . 05 / min ,再以一0 . 5 / min的速度从一6一一40 ) ; dmso的保护效应浓度为12 . 506左右;小牛血清的浓度对泥鳅胚胎细胞的成活率影响不明显;囊胚晚期细胞抗冻性比中早期强;通过对不同批次的冻存细胞解冻培养,解冻后成活率为30 %以上细胞培养数天后均有少数细胞贴壁,但只发现两瓶培养细胞有明显增殖现象产生许多未分化的小细胞。
