| 1. | Maximum allowable concentration of pollutants in atmosphere for protection crops
保护农作物的大气污染物最高允许浓度 |
| 2. | Regulation for concentration of pollutants in the workplace air for destruction of chemical weapons abandoned in china by japan
销毁日本遗弃在华化学武器工作区空气中污染物浓度标准试行 |
| 3. | The concentration of pollutant is high and its discharging is concentrated during urbanization , which was pushed by industrialization in southern jiangsu
在苏南工业化推动下的城镇化过程中，对水环境的影响具有污染物浓度大、排放集中的特点。 |
| 4. | Electric field concentration of pollutant aerosols : association with cancer remains to be tested . professor denis l . henshaw , phd , h . h . wills physics laboratory , university of bristol , u . k
摘要：电磁场聚集有害物质和尘埃可能是在电力线附近癌症风险增加的原因。 |
| 5. | It is especially advantageous to use the adsorption operation for treating gaseous pollution with low concentrations of pollutants such as odor and organic solvent vapor
尤其是处理含有低浓度气体污染物质具有优势，因此很适合用来控制排放之臭味问题或有机溶剂蒸气问题。 |
| 6. | However , there has not been much reduction in the concentrations of pollutants in the general ambient air . taking rsp , its average concentration has been on an increasing trend
相对来说，一般空气中的污染物浓度则没有多大改善，以可吸入悬浮粒子的平均浓度计算，更有上升的趋势。 |
| 7. | The results show that the higher the wind velocity is , the faster the concentration of the pollutants will attenuate after the pollutants leave the tunnel portal ; while the transversal wind will result in the higher concentration of pollutants in a large range around the tunnel portal
计算结果表明，风速越高，废气离开峒口后，浓度衰减得越快；而横向风则会导致隧道两侧很大区域内的污染物浓度超标。 |
| 8. | Amp and adp were not significantly changed throughout the experiments , pa tended to decreased with the increases of concentrations of pollutants , nitrite - na and sodium polyphosphate could decrease atp , while methyl parathion showed a disordered atp change . aec , atp / adp and total adenylate content solely could be poor health condition markers . pa and atp are proposed as direct health condition markers of an organism to environmental stress
整个实验中未发现腺苷一磷酸( amp )和腺苷二磷酸( adp )有显著变化，磷酸精氨酸随着化合物浓度升高呈下降趋势，亚硝酸钠和多聚磷酸钠能引起腺苷三磷酸( atp )下降，而甲基对硫磷中atp变化混乱。 |
