求翻譯一段話： 用DSC研究了熔融溫度與熔融時間對PC/PU共混體系中PC結(jié)晶行為的影響。不同的熔融溫度和熔融時間對共混物的結(jié)晶行為影響表明，在相同的熔融溫度條件下，PC的結(jié)晶峰溫度隨著熔融時間的延長向低溫方向移動，結(jié)晶峰溫度和結(jié)晶焓值逐漸降低，結(jié)晶峰逐漸變寬；在相同的熔融時間條件下，PC的結(jié)晶峰溫度隨著熔融溫度的提高向低溫方向移動，結(jié)晶峰溫度按200℃>220℃>240℃降低。 |

It is concluded, from the different influence of fusion temperature and time, that under the same fusion temperature, Tc of PC gets lower with the prolonging of the fusion time. Meanwhile, the enthalpy of crystallinity gets lower and the width of the peak gets broader. Under the same fusion time, Tc of PC gets towards a lower temperature with the increase of fusion temperature. Tc gets lower according to the sequence of 200℃>220℃>240℃. |

| DSC was used to study the impact of the fusion temperature and time on the crystallinity of PC in PC/PU blends. Different melting temperature and melting time on the crystallization behavior of blends impact that the melting temperature in the same conditions, PC with the melting temperature of the crystallization peak time shifts to low temperature, crystallization peak temperature and crystallization enthalpy decreases , crystallization peak becomes wider; at the same time under the conditions of melting, PC crystallization peak temperature increased with the melting temperature shifts to low temperature, the crystallization peak temperature by 200 ℃> 220 ℃> 240 ℃ lower. |

| The effect of the fusion temperature and time on the crystallinization behavior of PC in PC/PU blends was investigated by differential scanning calorimetry (DSC).The influence indicated that on the same condition with the prolonging of the fusion time ,the crystallization peak shifting to low temperature , crystallization peak temperature and crystallization enthalpy decreased and crystallization peak became wider.When fusion time was same, with the increase of melting temperature ,crystallization peak temperature of PC shifted to low temperature, which decreased by 200 ℃> 220 ℃> 240 ℃ . |
