Abstract
Thermograviometric study of DNA hydrate in the temperature range 0--120 degrees C was carried out. The three-stage hydration was observed: the first stage within 20--32 degrees C, the second--70--95 degrees C and the third one--105--116 degrees C. An assumption is advanced concerning the nature of structural rearrangements related to the loss of water in the system DNA--water. High sensitivity of thermograviometry to initial water content in DNA hydrate was shown.
摘要
对DNA水合物在0至120摄氏度温度范围内进行了热重分析研究。观察到了三个阶段的水合作用：第一阶段在20至32摄氏度之间，第二阶段在70至95摄氏度之间，第三阶段在105至116摄氏度之间。针对与DNA - 水体系中水分损失相关的结构重排性质提出了一个假设。结果表明热重分析对DNA水合物中的初始含水量具有高灵敏度。
