This method shall not be used over a temperature range in which first-order phase transitions occur
该法不要用于出现一级相转变的温度范围。
Glass transition as a function of conversion
玻璃化转变与转化率的关系
Depending on the resin system,this is not always the case,especially if the course of the chemical processes differ depending on temperature
与树脂体系有关,情况并非总是如此,尤其若化学过程随温度而异
The resin can be measured in the soft state in the bending mode because carbon-fiber reinforcement has been used as a support material
用碳纤维增强物作支撑材料,因而以弯曲模式可在软状态对树脂进行测试。
Overlay heating and cooling experiments to verify the presence of a weak grass transition.
以调制的升降温实验区分相互覆盖的转变或反应,来确定弱的玻璃化转变。
It was suspected that this resulted from `crystallization of water that did not have time freeze due to the high cooling rate of the quench-cooled sample.
推测这是因水的结晶所致,由于骤冷试样的快速冷却,来不及结晶而被冻结。
method英语In practical terms,this means a method that can predict the reaction behavior or course of the conversion as a function of temperature and time for different conditions,that is,for conditions that cannot be measured directly because reaction times would be too long or too short.
就实用而言,这指这样一种预测方法,预测不同条件下的反应行为(即转化过程)与温度和时间关系的方法,该反应在通常条件下,因反应时间过长或过短而无法直接测量。
To determine the temperature of the first irreversible change(determination)for the printed circuit boards using TMA as a very sensitive method.
TMA测定印刷线路板最初的不可逆变化(分层)的温度,这是一种非常灵敏的方法。
