  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。

  3. Apply ecologically water - cooling type freezing system with quick freezing speed and good result. the frozen temperature may reach minus 30 celsius degrees

    採用水冷式冷凍系統，製冷速度快效果好，冷凍溫度30 。
  4. Finally, we can not use electric power but the engine of bus or subsidiary engine to drive air compressors of bus air conditions. because the change range of turnaround speed of engine is very wide, that brings difficulties in controlling the rate of flow of cold - producing medium. in the control of bus air - conditions, preventing evaporator from freezing to make the air - conditions work with high efficiency and controlling the temperature of railway carriage are the basic tasks in air - condition control

    與一般的建築空調相比，汽車空調的工作環境惡劣，條件差，控制難度要增加很多，主要體現在以下幾個方面：一是車外熱負荷變化大，難以確定控制參數；二是要求空調負荷大，而且要控制空調使其降溫迅速：三，不便於用電力作為動力源，必須用汽車發動機或輔助發動機來帶動壓縮機，當採用汽車發動機作為動力源時，由於汽車的車速變化大，發動機轉速的變化可從600r min到4000r min ，壓縮機轉速與發動機轉速成正比，其轉速變化高達7倍，給空調系統製冷劑流量控制帶來困難。
  5. 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、密度和凍結速率三個基本輸入參數，預測粉質土的凍脹率，進而分析對鐵路工程建設的影響。
  6. So an equation, which calculates the annual times of pavement concrete natural freeze - thaw cycle was developed and the cycle parameters, including temperature decreasing speed of freezing, length of freezing time and lowest freezing temperature were statistically calculated
