The focus of the paper is the research which goes deep into the rpr fair algorithm .

本文的重点是对rpr中的带宽公平分配算法进行深入的研究。

And the rpr fair algorithm is the guarantee of effective usage of the bandwidth resources .

其中带宽公平算法是带宽资源高效利用的保证。

Rapid plasma reagin ( rpr ) test , treponema pallidum hemagglutination ( tpha ) test and cerebrospinal fluid ( csf ) venereal disease research laboratory ( vdrl ) test were positive in all the patients .

所有患者血清快速血浆反应素环状卡片试验（rpr）及梅毒螺旋体血球凝集试验（tpha）均阳性，脑脊液性病实验室检查试验（vdrl）阳性。
