| Abstract: | 【Objective】The purpose was to determine the temperature changing law when semen was frozen under different temperature conditions,【Method】By using computer proceeding apparatus and automatic digital measurement apparatus,the change of recovery rate of semen was detected under different temperature conditions.【Result】The results showed that the recovery rate of semen was the highest when the semen was frozen at 98 ℃.The recovery rate of semen was higher at the temperature range from 86℃ to 118 ℃,and the fitting velocity fell in the temperature of semen was 35 ℃/min.【Conclusion】The cooling rate of controlling the phase transformation of semen was the most important during making frozen semen, |
