求翻译：反应过程中，初始浓度较大的反应体系产生的产物及中间产物浓度也相对较大，因此，在降解过程中，与BPA竞争同样同活位，而造成初始浓度大的降解率变低。是什么意思？

Reaction process, the initial concentration of the reaction system to produce the product and intermediate product concentrations are relatively large, therefore, in the process of degradation, with bpa competition also live together bits, resulting in the degradation rate of the initial concentrati

In response, the initial concentration of a large response from the System Center Product and Product concentration are also relatively large, and therefore, in the process, and live with BPA competing for the same place as a result, the initial concentration of the degradation rate is low.

In the reaction process, the initial density big reacting system produces product and intermediary product density also relative big, therefore, in degeneration process, with BPA competition similarly with live position, but creates the initial density big degeneration rate to change low.

During the reaction, and initial concentration of larger reaction systems have a relatively larger concentration of products and intermediate products, therefore, during the degradation process, with BPA compete equally with the living, initial degradation rate of concentration change caused by low.
