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。
