  1. 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:以細胞培養液m199 (含2既的小牛血清,常規量雙抗)為凍存稀釋液對泥鰍胚胎細胞冷凍保存宜採取先慢后快的方式(例如,從0一一6 ,凍存速度為一0 . 05 / min ,再以一0 . 5 / min的速度從一6一一40 ) ; dmso的保護效應濃度為12 . 506左右;小牛血清的濃度對泥鰍胚胎細胞的成活率影響不明顯;囊胚晚期細胞抗凍性比中早期強;通過對不同批次的凍存細胞解凍培養,解凍后成活率為30 %以上細胞培養數天後均有少數細胞貼壁,但只發現兩瓶培養細胞有明顯增殖現象產生許多未分化的小細胞。
  2. With using once artificial freezing method and natural freezing method test the compressive strength of low - temperature concrete at different age and by testing the loss percentage of water ( content of evaporative water ) of saturated specimen test the pore porosity of low - temperature concrete at different age

    方法採用恆低溫一次凍結法和自然變低溫多次凍結法,測定混凝土在不同齡期的強度值,利用可蒸發水含量法測定對應齡期的孔隙率。
  3. The models have only one unit system : c. with the indication of the percentage we may know the freezing point of either ethylene glycol or propylene glycol based cooling systems. and they can also be used to test the concentration of ethylene glycol or propylene glycol in antifreeze liquids

    該型號折射儀被用於測量以乙二醇和丙二醇兩者為基的汽車冷卻系統水溶液的冰點溫度值和濃度百分比,它還可以檢查蓄電池內電解液的比重及使用狀態。
