Enrich employees' lives by forming teams to participate in the park sports meeting.

Under the arrangement of the administration and human resources of Lier, a team of 22 athletes actively participated in the 17th Employee Sports Meeting of the park. The main events included men's 5000-meter long-distance running, women's table tennis, men's badminton, and fun sports events. Although they did not achieve outstanding results, it enriched the employees' lives and fostered their spirit of striving. We wish this sports meeting a great success.

Hunan Lier Circuit Board Co., Ltd. Etching Waste Liquid Recycling and Regeneration System Project 4

5.3.2 Prediction Model This evaluation uses point source attenuation calculation formulas and multi-source superposition formulas to predict the noise of the project. The calculation formula is as follows: L(r) = L(r0) - (Adiv + Abar + Aatm) In the formula, LA(r) - the equivalent A sound level at prediction point r, dB(A); LA(r0) - the equivalent A sound level at a distance r0 from the sound source, dB(A); Adiv - the geometric divergence attenuation of the point sound source, dB(A); Abar - the attenuation caused by obstacles, dB(A); Aatm - the attenuation caused by air absorption.
