At those sort of scales , the viscosity of the air becomes more important than its density .
在这些尺寸范围内,空气的粘性比密度更加重要。
This is the study of how materials flow , and it considers the many elements which give a liquid its overall viscosity .
流体学是关于物质流动的一种科学,它研究造成一种液体的粘度都包含哪些因素。
Add oil if the indicated level is too low . Make sure the oil conforms to the manufacturer 's recommended viscosity .
如果油表显示的油压太低,需要加油,以确保油能符合制造商的推荐粘度。
The alice experiment has confirmed the quark-gluon plasma is a ultra-low viscosity liquid at these energies .
alice实验已经确认了在这样的能量下,夸克胶子等离子体是一种超低粘度的液体。
Researchers modeled the density and viscosity of various water-ice mixtures to determine how quickly such a pocket of liquid water-which is substantially denser than ice-might sink .
研究人员模拟了各种水冰混合物的密度和粘性,来确定实质上比冰密度更大的小范围液态水下沉得有多么快。
This process could enable the cells to pass through the blood in a more streamlined fashion , thus reducing the blood 's viscosity .
这个过程能够使细胞以一种更通畅的方式通过血液,因而会减小血粘度。
In fact , the fangs of most toxic serpents have external grooves that direct the flow of poison . And the venom 's viscosity is key to getting it where it needs to go . So says a study in the journal physical review letters .
Other causes include loss of antifoam additives , suction leaks , poor reservoir design , using the wrong viscosity or using too much antifoam additive .
