particle tracing method 颗粒示踪法
The result shows that the Particle-tracing Method is not only less diffusive , but also more conservative.
结果显示质点跟踪法不仅耗散更低，而且守恒性也更好。
Without repeated interpolations such as in ELM, the Particle-tracing Method reduces the numerical diffusion quite a lot.
因为没有像欧拉·拉格朗日方法那样反复插值，所以质点跟踪法极大地降低了数值耗散。
In this modeling, the Particle-tracing Method is again compared with the improved ELM by calculating the concentration of COD.
在该模拟中，本文通过对COD浓度的计算，又把质点跟踪法和改进后的欧拉·拉格朗日方法作了比较。
