Blow-down noise is an important source of noise pollution, and rather bulky and complex constructions are needed in order to reduce it to a degree harmless to people, by ordinary methods. In recent years, investigations show that the hazardous noise will be greatly reduced by replacing the large exhaust nozzle with a number of small nozzles, and quantitative relations were found. Based on these relations, simple and inexpensive micropore mufflers are developed, attaining noise reductions of more than 40dB....

Blow-down noise is an important source of noise pollution, and rather bulky and complex constructions are needed in order to reduce it to a degree harmless to people, by ordinary methods. In recent years, investigations show that the hazardous noise will be greatly reduced by replacing the large exhaust nozzle with a number of small nozzles, and quantitative relations were found. Based on these relations, simple and inexpensive micropore mufflers are developed, attaining noise reductions of more than 40dB. At low pressures, however, the diffuser-mufflers are very effective, the flow diffusion theory for such kind of mufflers is also developed in this paper.

排气噪声是噪声污染的重要祸源,用一般消声方法使它降低到对人无害的程度,常需要构造复杂的庞大装置.在近几年的研究工作中,我们发现用多数小喷口代替排气的大喷口可使其所产生的噪声中对人干扰的部分大大减少,并求得定量关系.根据这种关系而设计的小孔消声器,构造简单,价格低廉,在大型排气系统中可降低噪声到40分贝以上.不用小孔特性,而利用气流扩散原理所得的扩散消声器,在低压时也非常有效.本文也提出定量关系.

The obtained results demonstrated that a typical soil fungus No. 202 and bacterium No. 91 are able to oxidize B(a)P which is a potent carcinogen and one of the hazardous environmental pollutants. However, cis-dihydroxy-dihydro-B(a)P formed from B(a)P by bacterium No. 91 was unidentified because no authentic sample was available. Rest of other metabolic products was similar to Cerniglia's results and products by mammalian microsomes.

本试验证明,典型的土壤真菌202号和细菌91号能氧化B(a)P。细菌氧化B(a)P的产物除顺式二氢二醇无标准品未鉴定外,其余的产物与真菌的相同。 真菌产黄青霉氧化B(a)P为反式9,10-二氢二醇-B(a)P,反式-7,8-二氢二醇-B(a)p,1,6-醌-B(a)P,6,12-醌-B(a)P,3,6-醌-B(a)P,9-OH-B(a)P,3-OH-B(a)P。 用标记~(14)CB(a)P试验,真菌产黄青霉氧化B(a)P的动力学研究指出,在96小时内能氧化B(a)P2.8%,氧化产物包含水溶性的和酯溶性的。 氧化后的B(a)P产物的最大吸收光谱与B(a)P的不同,不能用常规检定B(a)P的方法检出,但其部分产物仍具致癌作用。为了弄清B(a)P在土壤中的转化,必须进一步研究B(a)P在土壤中与其它物质的结合和钝化。

Twenty-seven hazardous organic compounds in Beijing wastewater River have been investigated. They fall into four categories:phenols, pesticides nitrosamines and polycyclic aromatic hydrocarbons.The compounds in water and sediment were identified and quantified respectively. It was found that the concentrations of phenol, p-cresol,2,4-dichlorophenol, and trichlorophenol have gone beyond the maximum allowable level in river water, that 15 of the compounds belong among the U. S. EPA priority pollutants, and...

Twenty-seven hazardous organic compounds in Beijing wastewater River have been investigated. They fall into four categories:phenols, pesticides nitrosamines and polycyclic aromatic hydrocarbons.The compounds in water and sediment were identified and quantified respectively. It was found that the concentrations of phenol, p-cresol,2,4-dichlorophenol, and trichlorophenol have gone beyond the maximum allowable level in river water, that 15 of the compounds belong among the U. S. EPA priority pollutants, and that 5 are potential carcinogenic substances.

对北京排污河水和底泥中四类主要有机污染物(酚类,农药类、亚硝胺类和多环芳烃类)进行了定量调查。检出27种有毒有机物,其中4种超过地表水允许浓度;检出率50%以上的15种;属于美国环保局规定的优先监测污染物15种;潜在致癌物5种。结合这些化合物的环境毒性进行了综合分析评价。
