In this paper, productive experiment was conducted on biological ceramisite filter, one of BAFs, to pretreat the upstream water of Huangpu River at the scale of 5000t/ d.

The improvement test of typical two-stage up-flow biological aerated filter ( UBAF) with ceramsite was performed using the characteristics of different flow BAFs and the optimized backwash operation.

利用不同流向BAF反应器的特性以及优化反冲洗操作，对典型的两级上向流陶粒曝气生物滤池工艺进行改进试验。

Biological aerated filters ( BAFs) is a recently developed process for wastewater treatment, media selection is critical in the design and operation of BAFs to achieve qualified effluent quality requirements.

曝气生物滤池是一种新兴的污水处理技术，填料的选择是滤池设计和影响出水水质的关键因素。

Influence of air-water ratio on performance of two BAFs was explored.

探讨了气水比（从2：1～12：1）对两BAFsss的效能的影响。

不同流向BAF硝化影响因素的对比试验

Developing new media is a new approach to improve removal efficiency of BAFs.

开发新型填料是提高曝气生物滤池效能的有效途径。

In a word, polyurethane sponge is suitable for being used as media in BAFs.

总之，作为一种新型填料，聚氨酯海绵适合做曝气生物滤池工艺填料，并有一定的应用前景。

A new soft-output algorithm of decoding is derived from the Bahl algorithm.

本文在Bahl算法的基础上给出了一种新的软输出译码的矩阵算法。

By 2020 – partly thanks to a one-child policy that Bahl says could never have been imposed in India – China will be in the throes of ageing.

到2020年，中国将面临人口老龄化的痛苦&这在一定程度上归因于独生子女政策；巴尔称，印度永远不会实施这种政策。

But China is vulnerable, argues Bahl.

但巴尔提出，中国是脆弱的。

CWA President Morton Bahr, an elder statesman of the federation, opposed Sweeney in1995, figuring a power struggle was bad for labor, even though he agreed with Sweeney's goals.

CWA的会长Morton Bahr，作为一名联邦的政界元老，在1995年曾反对Sweeney，指出权利斗争对劳工不利，虽然他认同Sweeney的目标。
