求翻译：由图3.6可知，盐酸四环素的降解率随着TiO2微米管表面银的负载量增加而逐步上升。在不载银时，催化110分钟后，降解率为80%左右，而在银的负载量为20%时，催化110分钟后的降解率达到87.5%左右。说明TiO2微米管负载银以后，光催化效果得到了增强，且负载量为20%的效果最显著。是什么意思？

3.6 may know by Figure, but the hydrochloric acid tetracyclin degeneration rate increases along with the TiO2 micron tube-surface silver capacity rises gradually.When does not carry the silver, after catalyzes 110 minutes, degrades rate is about 80%, but when the silver capacity is 20%, catalyzes 11

In Figure 3.6, the degradability of tetracycline hydrochloride with silver on the surface of the TiO2 Micron tube load gradually increased. When not in silver, catalytic after 110 minutes, degradation rate is about 80%, and silver when the load is 20%, catalytic degradation rate of 87.5% after 110 m
