pollution distribution
1.For the fine particle pollution, the distribution of PM2.5 observed at the spot BDC may be regional, and to a certain extent, cloud be the a representative of the city Beijing.
2.The voltage control of dc link in UPQC is achieved byusing Active Power Factor Correction (APFC) technology. The technology not onlyensures that the energy storage unit of UPQC is charged in high power factor, but alsoavoids that it causes harmonic pollution to distribution network.
3.A STUDY ON POLLUTION CONDITION AND DISTRIBUTION LAW OF TETRAETHYL LEAD IN AMBIENT AIR OF BEIJING AND TIANJIN CITIES
5.The relation between acid rain and atmospheric pollution, the characteristics of its space-time distribution and the characteristics of space-time distribution of yts chemical con-stitrtion were analysed and put tentativey forward conntermeasures of controlling acid rain through monitoring dada during five years(1993- 1997) in Yueyang City.
6.DISTRIBUTION OF GROUNDWATER SALT POLLUTION AND THE POLLUTING MECHANISM IN SHIJIAZHUANG
7.REGULARITIES OF DISTRIBUTION OF ACIDIFY & POLLUTION COMPOSITION OF ACID DEPOSITION IN CHONGQING AREA
8.OCCURRENCE AND DISTRIBUTION OF SAPROLEGNIACEAE IN WATERBODIES WITH DIFFERENT LEVELS OF POLLUTION IN BEIJING DISTRICT
9.Distribution Characteristics of Nitrogen and Phosphorus Pollution in the Surface Water Source of Shijiazhuang City
10.On the basis of monitoring present pollution level and investigating emission sources of VCM in a certain area of Tianjin, the objectives of total quantity control and the load distribution plan were put forward for air pollutant VCM in this area, and the feasibility of the objectives was analysed and proved.
