Erich Lamprecht, and tribological behaviors of nanometric diamond particles in lubricating oils were studied in this chapter. The dispersion characteristics of modified nanometric diamond in lubricating oils were observed by centrifugal and static methods. The four-ball tribometer was performed to study the tribol思想 发表于 2025-3-23 15:45:37
Erich Lamprecht. Research to date has shown that the ideal pedal rate varies based on the particular cycling task, such as course geography and duration. Several components of a CVT bicycle were analysed using SolidWorks finite element analysis to determine the von Mises stress. These results were used to determinangina-pectoris 发表于 2025-3-23 22:01:55
