Title: Lixia Sun: Inventor in Sediment-Motion Research

Introduction

Lixia Sun is an inventor associated with Zhejiang University in Hangzhou, China. Her patent work addresses experimental methods for studying how nonuniform sediment moves under flowing water.

Latest Patents

Sun is credited with 1 patent: “Experimental Device and Method for Measuring Motion Probability of Nonuniform Sediment.” The invention describes a flume-based experiment that uses dyed sediment of different particle sizes and a rough plate formed by attaching sediment of matching grades to the flume bottom. After the flow stabilizes, a sediment feeder introduces the prepared material, and the test continues until the sediment stops moving. Researchers then collect, dry, sieve, and weigh sediment from bedload and suspended-load collectors. Comparing the collected amounts with the initial quantities allows them to calculate the incipient-motion and suspension probabilities for different sediment grades.

Career Highlights

Sun’s listed patent reflects research focused on measuring sediment transport and distinguishing the movement behavior of particles with different sizes. The method provides an experimental framework for quantifying when sediment begins to move and when it becomes suspended.

Collaborations

The provided information lists Zhilin Sun and Yizhi Sun as Sun’s coworkers. It does not specify their roles in the patent or the nature of their collaboration.

Conclusion

Lixia Sun’s patent presents a structured experimental approach to measuring the motion probabilities of nonuniform sediment, contributing a practical method for sediment-transport research.
