Differential scanning calorimetry ( DSC) was used to study the constant rate heating and cooling and the isothermal crystallizing behavior of the two component PEG system. The characteristic parameters at different temperatures were examined and the heat of exotherms and endotherms was measured.
采用差示扫描量热法(DSC)对二元聚乙二醇(PEG)体系的等速升降温性能及等温结晶性能进行了研究,并对各温度特征参数及熔融、结晶热作了表征。
Scanning Speed: A good anti-virus program will not only have a high rate of detection but it will also scan for infections in a decent time frame.
扫描速度:良好的防病毒程序,不仅有较高的检测率,但它也将扫描帧感染一个体面的时间。
