Total organic halogen (TOX) is widely used as a surrogate bulk parameter to measure the overall exposure of halogenated disinfection byproducts (DBPs) in drinking water. In this study, we surprisingly found that level TOX chlorinated waters had been significantly underestimated under common analytical conditions. After addition quenching agent sodium thiosulfate, total chlorine and bromine exhibited two-phase decomposition pattern with increasing contact time, significant was observed for...

The structure of non-pneumatic tire is complex and various, but its performance superior to ordinary tire, so it has broad prospects. In this paper, a design method honeycomb was proposed based on tangent method, the hexagonal circular were established. rules displacement, radial stiffness ground pressure with different density studied. Meanwhile, most basic bearing analyzed by finite element under static conditions. results show that increases increase density. When small, capacity stronger...

A high-accuracy gridding vehicle emission inventory is not only the foundation for developing refined control strategies but a necessary input to air quality model as well. An accurate approach spatiotemporal disaggregation key step improving accuracy of inventories. The existing spatial method considers relatively fewer impact factors, lacking adequate correlation analysis among factors. Additionally, temporal does correspond with actual travel behavior residents. This paper proposes...
