... groove of the outer cylinder, achieving axial fixation between the inner and outer cylinders. This reduces axial displacement and improves the reliability of power supply and communication. Use the surface controller to test power and communication signals. Once normal transmission is confirmed, apply...

..., and organic acids. Through a series of controlled experiments using turbidity measurements, transmission analysis, and the Turbiscan Stability Index (TSI), the effects of these variables on emulsion stability were systematically evaluated. The findings reveal that higher shear rates and presence...
