胶原纤维heat capacity的脉冲差示扫描量热法测定
Pulsed differential scanning calorimeter measurement of collagene fiber heat capacity
摘要：
本文给出了鼠尾腱胶原纤维在水中熔化时热容跃变的估计。测量是由作者设计的原始量热系统进行的，与现代差示扫描量热仪在非平衡条件下进行测量相比，由于扫描过程中样品的连续加热，该系统允许在平衡条件下在扫描状态和脉冲状态下进行测量。在远离脉冲制度中的相变的地方进行的测量允许在平衡条件下精确地确定转变之前和之后的热容。结果，在熔化时确定了平衡条件下热容跃变的精确值。
英文摘要：
The work gives the estimation of the heat capacity jump at melting in water of collagen fibers of rat tail tendons. The measurements were carried out by an original calorimetric system designed by the authors, which in contrast to modern differential scanning calorimeters making the measurements under not equilibrium conditions due to the continuous heating of samples during the scanning, allows make the measurements both in scanning regime and also in pulsed regime under equilibrium conditions . The measurements carried out far from the phase transition in the pulsed regime allowed to determine exactly under equilibrium conditions the heat capacity before and after transition. As a result, the exact value of heat capacity jump under the equilibrium conditions was determined at melting.
