The relations between the secondary relaxation and transition of poly ( arylene ether sulfone) with Cardo and ( PP/ Bis-T) PES copolymers and their structure are described. PES-C,(PP/Bis-T)PES的次级松驰与转变描述了酚酞型聚芳醚砜(PES-C)的次级松驰和转变与其结构的关系。
The secondary relaxation is attributed to the local motion of the chain segments of polyurethane component. 介电损耗谱上的次级松弛是COPU链段运动的贡献。
There are two kinds of theory for the vacuum surface flashover: secondary electron emission avalanche ( SEEA) and electron triggered polarization relaxation ( ETPR). 研究真空表面闪络过程有两类理论:二次电子发射崩溃(SEEA)和电子引发极化松弛(ETPR)。
Two basic theories were introduced:? Secondary Electron Emission Avalanche ( SEEA) theory and Electron Triggered Polarization Relaxation ( ETPR) theory, summarizing the impact factors that affect the insulating material surface flashover and suppression measures. 介绍了沿面闪络的两大基本理论:二次电子崩理论和电子极化松弛理论,概括了影响绝缘材料沿面闪络的因素以及抑制措施。
This mainly is because secondary debt environmental variation result, including credit condition relaxation, interest rate undulation, house price undulation and securitization market not standard and so on. 这主要是由于次级债环境变化所致,包括信贷条件的放松、利率的波动、房价的波动及证券化市场的不规范等。
