degree of undercooling造句

• In the isothermal crystallization experiment , the dsc exothermic curves become flat as decrease of the degrees of undercooling within the experimental temperatures
  在等温结晶实验中，在所测试的结晶温度范围内，随着过冷度的减小， dsc放热曲线趋于变缓，结晶完成时间延长，结晶速率减小。
• At a given cooling rate , the degree of undercooling increases with increasing overheated temperature , and tends to be constant at last . it suggests that higher undercooling can be reached by increasing the overheated temperature in a stated range . at a given overheated temperature , the undercooling increases with cooling rates within the range of measurement
  在冷却速率一定的情况下，熔体的过冷度随着过热度的增大而增大，而随着过热度增大到一定程度，熔体的过冷度趋向于常数；这说明采用dsc与助熔剂处理技术研究熔体的过冷现象时，可以通过在一定范围内提高过热度来获得较大的过冷度。
