Samples of suspended particulate matter were collected during the period of 26 Oct-4 Nov. 1982 and 27 Jan-2 Feb. 1983 in five sampling locations of Beijing. Non-polar, moderately polar, polar and strongly polar fractions of particulate organic matter POM were separated by 8h sequential Soxhlet extraction with cyclohexane, dichloromethane, acetone and methanol, respectively. Atmospheric concentrations of total POM were averaged at 111.7μg/m3 for non space heating periods and 129.7μg/m3 for space heating periods....

Samples of suspended particulate matter were collected during the period of 26 Oct-4 Nov. 1982 and 27 Jan-2 Feb. 1983 in five sampling locations of Beijing. Non-polar, moderately polar, polar and strongly polar fractions of particulate organic matter POM were separated by 8h sequential Soxhlet extraction with cyclohexane, dichloromethane, acetone and methanol, respectively. Atmospheric concentrations of total POM were averaged at 111.7μg/m3 for non space heating periods and 129.7μg/m3 for space heating periods. Factor analysis was used in identifying emission sources of air pollutants. Four emission sources of air pollutants have been found in Beijing by this analysis. The regression model was formulated using multiple regression analysis, which is a statistical technioue for estimating the relative contribution of several sources of air pollutants to particulate organic matter POM. The model when applied to data from Beijing indicates that about 14.5% of POM is due to blown sand and soil, while motor vehicle and oil burning about 7.8%, coal burning about 20.3%, secondary pollution about 32.5% and other sources about 24.9%.

本文用大气颗粒物中13种元素(W、As、Br、K、Ba、Rb、Ce、Sc、Fe、Zn、Sb、Ni、V)和4种有机溶剂萃取物(NP环已烷萃取物、MP二氯甲烷萃取物、P丙酮萃取物、SP甲醇萃取物)的测定值作为变量,用富集因子法、因子分析法、多元回归法识别了北京地区主要污染源,并计算了它们对颗粒总有机物POM(NP+MP+P+SP)的贡献率.其贡献率:风砂土壤14.5%;煤炭燃烧20.3%;汽车燃油7.8%;二次污染32.5%;其它污染源24.9%.

Stable free radicals′ESR signals,g=2.11-2.14,spectral widthabout 420 G,have been found in atmospheric dust in different areas inLanzhou district.The stable free radical concentration followed certainrules.A place,the more trees and grasses,the lighter traffic and theless factories,where the lower concentration of free radicals.The con-centration of free radicals increased with the thickness of inversion layerincreased,both correlated each other.It seems that the concentrationof free radicals to a certain degree with the precipitation decreased.The concentration of free radicals higher in winter and spring,and lowerin summer and autumn.This phenomenon is the reflection of the ruleof seasonal varieties of the inversion layer thickness and the precipitation.The round the clock variety of free radicals concentration is similarto the round the clock variety of SO_2 concentration and the round theclock traffic amount of vehicles in the same area.

兰州市大气飘尘中具有 g 值为2.11-2.14,波谱线宽为420高斯左右的稳定性自由基.根据四年的测定资料发现:它们的浓度变化有一定的规律,绿化区、非交通要道,工厂少的地区大气飘尘中自由基浓度低:反之,浓度就高.自由基浓度也随逆温层低层厚度的增加而增高,二者密切相关,呈线性关系,与逆温层贴地层的厚度也有一定关系.自由基浓度在一定程度上随降量的增加而减少.自由基浓度在冬春两季较高,夏秋两季较低,这正反映了逆温层厚度与降水量因季节而异的规律.自由基浓度的日变化与兰州市 SO_2浓度日变化以及机动车昼夜通过量的变化趋势相似.

The smoke suppressing effect of organic barium salt, a product of the reaction between barium bioxide and naphthenic acid in coking gasoline, as a diesel oil additive was studied. The dest test of engine showed that the smoke suppression rate in a range of 40.9 to 66.3 percent and the decrease of energy consumption from 0.36 to 4.42 percent could be achived when 0.05 to 0.15 percent (wt. by Ba) of the additive was added. The results of the vehicle driving test indicated that with 0.1 percent of the additive...

The smoke suppressing effect of organic barium salt, a product of the reaction between barium bioxide and naphthenic acid in coking gasoline, as a diesel oil additive was studied. The dest test of engine showed that the smoke suppression rate in a range of 40.9 to 66.3 percent and the decrease of energy consumption from 0.36 to 4.42 percent could be achived when 0.05 to 0.15 percent (wt. by Ba) of the additive was added. The results of the vehicle driving test indicated that with 0.1 percent of the additive added, the smoke suppression rate was 67.7 percent and the fuel consumption decreased 5.21 percent.

本文介绍一种以有机钡盐为主的复合型柴油添加剂,其主要成分是过氧化钡与环烷酸在焦化汽油中反应所生成的环烷酸钡。台架实验结果表明,该添加剂在柴油中添加量为0.5—1.5‰(重量,以钡计)时,取得了消烟率40.9—66.3%、节能0.36—4.42%的效果。行车试验也证明本添加剂具有优良的消烟节能作用,当添加量为1.0‰(重量,以钡计)时,平均消烟率为67.7%,节油5.21%。
