Understanding the complexity of dissolved organic matter（DOM）in stormwater has drawn a lot of interest,since DOM from stormwater causes not only environmental impacts,but also worsens downstream aquatic quality associated with water supply and *** study introduced and employed high-performance size exclusion chromatography（HPSEC）coupled with an ultraviolet–visible（UV–vis）diode array detector to assess changes in stormwater-associated DOM *** DOM was also analysed in relation to storm event characteristics,water quality and spectroscopic *** tools were used to determine the correlations within DOM and water quality *** showed that dissolved organic carbon（DOC）and UV absorbance at 254 nm（UV（254））as conventional DOM parameters were found to be correlated well to the changes in stormwater quality during each of the three storm events *** detector wavelengths（210and 254 nm）and their ratio（A（210）/A（254））were found to provide additional information on the physiochemical properties of stormwater-associated *** study indicated that A（210）/A（254） is an important parameter which could be used to estimate the DOM proportions of functional groups and conjugated carbon *** study provided also an understanding of stormwater quality constituents through assessing variability and sensitivity for various parameters,and the additional information of rainfall characteristics on runoff quality data for a better understanding of parameter correlations and influences.

针对航空线缆路径规划问题,提出一种非栅格化处理的关节点寻路算法。引入“基线”概念,首先通过基线和布线环境信息求得初始关节点集合,将路径规划问题转换为关节点集合的优化选取问题;然后依据障碍物信息进行关节点的冗余关节点筛选优化;再对去除冗余点的关节点集合进行迭代优化,以路径最优为收敛条件进行关节点的添加和删除;最后利用关节点作为布线路径节点,获得线缆路径。实验结果表明,关节点寻路算法可以有效减少线缆布线的弯折次数和线缆长度,并在布线时间上较优。

This study examined the associations between dissolved organic matter（DOM） characteristics and potential nitrification occurrence in the presence of chloramine along a drinking water distribution system. High-performance size exclusion chromatography（HPSEC） coupled with a multiple wavelength detector（200–280 nm） was employed to characterise DOM by molecular weight distribution, bacterial activity was analysed using flow cytometry, and a package of simple analytical tools, such as dissolved organic carbon, absorbance at 254 nm, nitrate,nitrite, ammonia and total disinfectant residual were also applied and their applicability to indicate water quality changes in distribution systems were also evaluated. Results showed that multi-wavelength HPSEC analysis was useful to provide information about DOM character while changes in molecule weight profiles at wavelengths less than 230 nm were also able to be related to other water quality parameters. Correct selection of the UV wavelengths can be an important factor for providing appropriate indicators associated with different DOM compositions. DOM molecular weight in the range of 0.2–0.5 kDa measured at210 nm correlated positively with oxidised nitrogen concentration（r = 0.99）, and the concentrations of active bacterial cells in the distribution system（r = 0.85）. Our study also showed that the changes of DOM character and bacterial cells were significant in those sampling points that had decreases in total disinfectant residual. HPSEC-UV measured at210 nm and flow cytometry can detect the changes of low molecular weight of DOM and bacterial levels, respectively, when nitrification occurred within the chloraminated distribution system.
