Experimental results show that velocity slip do not obey the Beavers mode, but it could be approximated by an added equivalent clearance.
实验结果表明多孔质表面的速度滑移并不遵守Beaver模型 ,但是可以通过附加等效间隙来大致估计 。
Being quoted for the conditions that the bearing lubrication system of diesel generator has large volume,and bad reliability,this paper presents the method that the lubrication oil L-TSA68 should be replaced by the oil CD40 for diesel,explores the problems on selection of relative clearance and stability of operation of bearing,etc.
针对柴油发电机轴承润滑系统体积大、可靠性差的状况,提出采用柴油机用CD40油代替L-TSA68润滑油的方式,并对轴承相对间隙选定及轴承运转稳定性等问题进行探讨,最后通过试验验证方法的有效性。
The curves of transmission and reflection changing from the relative gap width d/λ , incident angle θ 0 , and refraction index n were proposed.
该文根据薄膜理论基础,分析了受抑全内反射(FTIR)的理论机制,导出相应的光线透射率及反射率公式,从透射率、反射率随棱镜相对间隙d/λ、入射角θ0及折射率n的变化曲线可以看出,当间隙从0增加到一个波长量级时,透射率T从100%下降到0;在间隙一定的情况下,增大入射角或选用大折射率的材料,都会使透射率减小。
