| 1 | Tire Defect Detection on Impurities显示文摘According to X-ray image texture tire characteristics and abnormal distribution of the gray area,this paper studies a real-time defect detection method about the sidewall of tire.On the basis of the texture distribution characteristics of X-ray tire,we extract the cord information of the tire image by maximizing the distance of the categories after the gray value correction,then we use the morphology method and statistics method to process the image so that we can get the location and the size of impurities.We can classify the tires into different grades by the information.Compared with other methods,our method has the advantage that meets the needs of tire industry. | ZHANG Mao-qiang GUO Qiang YANG Xingqiang | 2014 | Computer Aided Drafting,Design and Manufacturing2014，24，1： | 3 |

| 3 | Distribution and bioavailability of mercury in size-fractioned atmospheric particles around an ultra-low emission power plant in Southwest China显示文摘Ultra-low emission(ULE)technology retrofits significantly impact the particulate-bound mercury(Hg)emissions from coal-fired power plants(CFPPs);however,the distribution and bioavailability of Hg in size-fractioned particulate matter(PM)around the ULE-retrofitted CF-PPs are less understood.Here,total Hg and its chemical speciation in TSP(total suspended particles),PM_(10)(aerodynamic particle diameter≤10μm)and PM_(2.5)(aerodynamic particle diameter≤2.5μm)around a ULE-retrofitted CFPP in Guizhou Province were quantified.Atmospheric PM_(2.5)concentration was higher around this ULE-retrofitted CFPP than that in the intra-regional urban cities,and it had higher mass Hg concentration than other sizefractioned PM.Total Hg concentrations in PM had multifarious sources including CFPP,vehicle exhaust and biomass combustion,while they were significantly higher in autumn and winter than those in other seasons(P<0.05).Regardless of particulate size,atmospheric PM-bound Hg had lower residual fractions(<21%)while higher HCl-soluble fractions(>40%).Mass concentrations of exchangeable,HCl-soluble,elemental,and residual Hg in PM_(2.5)were higher than those in other size-fractioned PM,and were markedly elevated in autumn and winter(P<0.05).In PM_(2.5),HCl-soluble Hg presented a significantly positive relationship with elemental Hg(P<0.05),while residual Hg showed the significantly positive relationships with HCl-soluble Hg and elemental Hg(P<0.01).Overall,these results suggested that atmospheric PM-bound Hg around the ULE-retrofitted CFPP tends to accumulate in finer PM,and has higher bioavailable fractions,while has potential transformation between chemical speciation. | Wei Zhang Jinjuan Li Hao Qiu Xingqiang Guo Zhijun Fei Yi Xing Deliang Yin | 2024 | Journal of Environmental Sciences2024，，4： | 0 |
