The results have also demonstrated that the non Newtonian performance of multi grade engine oil is not observable at a shear strain rate less than 6 000 s-1 and below the temperature of 100 ℃. 在剪应变率小于6000s-1、温度低于100℃的范围内,多级油并未表现出非牛顿特性。
A strong ultraviolet emission peak at 3.26 eV was observed and the deep level emission band was barely observable at room temperature. 室温下观察到一束强的紫外(3.26eV)光致发光和很弱的深能级发射。
