The method was fast, steady and had low detect limit. The samples of TSP, PM10, PM2.5 and airborne particles with different diameters were collected at nine optimized sites of Jinan City in heating and non-heating season.
Applying matter element analysis to optimized sites of atmospheric monitoring,practical sites are obtainde,which proves that the method is practical and easily applied and provides beneficial reference to supervision departments to scientifically and reasonably designate monitoring sites.
A study by applying matter element ahalysis to optimized sites of atmospheric environmental monitoring. Through the comparison with the grey cluster analysis and fuzzy synthetic evaluaton,it is proved that this method is easlly applied,practical and exactand benehcial to supervision departments to scientifically and reasonably designate monitoring sites.
A dust sampler was prepared to collect dust-collectable dust, which is correlated with TSP (PM_(10)) and can show the changing tendency of TSP(PM_(10)) concentration in air. This simple equipment was used in the grid monitoring of optimization of sampling points of urban air in 15 cities of Shandong Province. This equipment has obtained National New Type Patent.
This method can show the NO_2 concentration level in urban air. It is precise and does not need the investment in equipment. This method was successfully used in the grid monitoring of the optimization of sampling points for air monitoring in 15 cities of Shandong province.
The optimum geometric dimensions of the honeycomb and its optimum location in the wind tunnel necessary to ensure a minimum level of turbulence in the working section have been determined.
The motion of electrons in a microtron with the second-type acceleration mode is calculated and an optimum location of the emitter in the cavity resonator is found, which permitted us to increase the current capture efficiency.
(1) The optimum location for FDIs from Hongkong - Macao lies in the coastal area, especially Guangdong, Hainan, Jiangsu, Shandong, Fujian provinces.
The more important issue of identifying the optimum location of the ribs has received little attention.
Methods for determining the optimum location site for the educational plant have traditionally classified the school as unifunctional in its production activities.
