Metal elements and water-soluble anion concentrations in winter fog water in Nanjing

This paper reported the analysed results of ions species in fog water collected at three sites in Chongqing during December of 2003,also compared with the results obtained ten years ago.

Based on the analysis of sampled fog water in the north suburb of Nanjing city during December 2006,study is conducted of heavy metals of fog water and air pollution in foggy weather.

The paper analyzes disquisition datum of obtained fog water sampling(from 2003yer to 2005yer) and raining water sampling(2005yer) at Nanshan(its altitude 1 922 m,58 km from Urumqi to Nanshan).

Nanshan with an elevation of 1?922 m is located at 58 km from Urumqi,the chemical compositions of the fog sampled in Nanshan by passive fog collector were analyzed,and the contributing factor and influence on the environment were discussed.

This paper reports pollution and chemical characteristics of fogwater in Chongqing in the period of the 10th five-year plan.

Application of water mist to extinguish lager oil pool fires for industrial oil cooker protection;

Fire fighting techn- ologies such as water mist fire fighting,rescue ro- bot,water curtain,sphere fire fighting facilities, microcapsule technology,fine dry powder fire ex- tinguishing technology and some new fire protec- tion technologies are described.

The present study aims to investigate the interactions between water mists and fires and show the influence of water mist on fire suppression by using of the non-spread diffusion flame of combustible solid porous beds.

Based on the field observation in Beijing from November 1 to December 20 of 1999, differences between heavy smog and fog are analyzed, and the structures of the atmospheric boundary layer for heavy smog and fog are discussed.

It is shown that the degree of depolarization characters of those man made fog have a gravity dependence in a specified direction, and demonstrated an opto electronic effect in the depolarization of the fog.

This paper focused on theoretical modeling of extinction characters of fog at near and middle infrared .

Application research of straightening with water fog for the welding deformation in thin plate;

Experimental research of sound absorption by water fog in duct sound elimination system;

Using water fog generator can generate large and dense water fog in short time, the water fog can effectively diminish the threaten to the naval vessel, which caused by infrared spotlight guided missile, infrared image guided missile and television image guided missile.
