By analyzing the framework of RRM based on BoD for broadband satellite systems, this article decomposed the framework into five main function parts.

在分析基于带宽按需分配的卫星无线资源管理体系结构的基础上，将其分解为5个主要功能部分，并将现有宽带卫星无线资源管理技术的研究成果分别对应到这5个功能，重点对每个功能近年来的实现算法进行了分类总结，并分析比较了各类算法的特点与存在的问题，最后就进一步的研究方向提出了建议。

By experimenting with solid-liquid separator in the treatment of sewage before it is discharged on three large scale pig farms, we come to the conclusion that solid-liquid separator is effective in gathering dung sullage, with about 2.9 t/h and the water content less than 55%. The average rates of removal of TS, COD, and BOD are 82.5%, 77.5% and 73.5%, respectively. ByKey words: FZ-12 solid-liquid separator; large scale pig farm; sewage treatment

为了了解FZ-12固液分离机前处理效果，对3个规模化猪场进行污水前处理试验，结果表明，FZ-12固液分离机能有效地收集粪渣，平均收集量为2.9t／h左右，粪渣含水率〈55％，对猪场污水的TS、COD和BOD平均去除率分别达到82.4％、77.5％和73.5％，应用该机处理猪场污水，增加相关投资约人民币5.3万元，收集的粪渣出售后，扣除运行成本，年可增收税利约人民币4.5万元，投资回报率达84.9%，约1.18年可收回投资，因此，应用FZ-12固液分离机处理猪场污水，具有广阔的应用前景。

It is pointed out that under the condition of the temperature of 1120℃, the reaction time of 16 mm and the carbon content of 27%, the metal transformation rate of sponge iron used for general metallurgy is up to 90%. But the optimal carbon content is 29% for iron sponge to treat DSD acid oxidation wastewater. Under condition of the wastewater's pH value of 3 to 5 and the reaction time of 40min, the removal rates of COD and color are 68% and 90%, respectively. The BOD/COD ratio is up to 0.425 when DSD oxidation acid water is treated with sponge iron.

研究表明：在配碳量27%、反应温度1160℃、反应时间16min的情况下，以铁泥为原料制备的常规海绵铁的金属化率可达90%以上；用于处理DSD酸氧化废水的海绵铁适宜配碳量为29%，用制备出的海绵铁处理DSD酸氧化废水，在pH值3~5、反应时间40min时，出水的COD去除率可达68%、色度的去除率达90%、可生化性指标BOD/COD提高到0.425。

Every body in the universe attracts every other body with a force directly proportional to the product of the masses of the two bod ie s and inversely proportional to the square of the distance between them.

宇宙中每一物体都以一引力吸引另外的每一物体，该引力与两物体质量的乘积成正比，而与两物体之间的距离平方成反比。
