The time-activity of workers was recorded manually during sampling, and the average exposure levels of nanoparticle mass concentrations and nanoparticle number concentrations to workers were calculated from the time-activity pattern and the mapping data. In the iron foundry plant, the worker with the highest exposure level was the crane driver whose average exposure levels of nanoparticle number concentrations and nanoparticle mass concentrations were found to be 5.17x104 ?q/cm3 and 11.39 ?慊/m3, respectively.

为了解工作人员的质量暴露浓度，本研究在采样的过程中利用人工的方式将工作人员的时间-活动模式加以记录，结合此时间-活动模式以及奈米微粒质量浓度分布图，可以推估出工作人员的平均奈米微粒数目浓度与质量浓度暴露量，其中铸造厂暴露浓度最高的工作人员为天车吊桶作业人员，其奈米微粒平均暴露数目浓度与暴露质量浓度分别为5.17x104 #/cm3、11.39μg /m3。

Results show that the mullite grogs can be gained by the method at 1700℃ as long as the control of the chemical composition of ingredients(content of Al2O3 and ratio of Al2O3/ SiO2 ,etc.) with apparent porosity＜2.5% and bulk density≥2.75g/cm3; the heating process can be divided three stages, which are formation of primary mullite, secondary mullitization stage and liquid phase sintering stage.Key words bauxite, coal gangue, mullite grogs

The results show that the composite is dense and silicon particles are distributed uniformly. Transmission electron microscope observations show that stacking faults with high density, twins and dislocations are found in silicon particles. The Si-Al interfaces are well-bonded and no interface reactants are found. The dislocations and eutectic silicon precipitates are observed in LD11 matrix. Sip/LD11 composite has low density of 2.4 g/cm3, low coefficient of thermal expansion of 8.1×10-6/K, high thermal conductivity of 161.3 W/, and the annealing treatment can reduce the CTE and improve the thermal conductivity.
