黏度梯度
A blood viscosity "Quality Control Substance" was studied for 3 years continuously for the apparent viscosity values, the curve gradient of viscosity versus shear rate, Casson yield stress and Casson viscosity, we found that above parameters decrease according to time going on.
对于一种血液粘度质控物进行了连续3年的表观粘度、剪切稀化曲线陡度、卡松屈服应力和卡松粘度的观察,发现该物质随着时间的进程上述参数逐年变低;
The low surface tension and low viscosity of aluminum alloys are the reason that the change of surface tension temperature gradient is not the main mechanism of activating flux increasing weld penetration of activating TIG welding.
而铝合金材料表面张力小,粘度低,是导致表面张力温度梯度改变不是活性剂增加铝合金活性TIG焊熔深的主要机理的重要原因。
