Injection drug use history was the main risk factor among FSWs(adjusted OR=9.8);(2) The self reported illicit drug-using behaviors and high risk sexual behaviors among close-cohort of FSWs who attended all the three cross-sectional surveys decreased accompanied with the survey time.The decrease of STIs prevalence and urine positive rate among them confirmed their decreased high risk behaviors;(3)The incidence of HIV was 1.4(95%CI 0.5～3.3)/100 Person Year in the open-cohort.FSWs who were recently HIV-infected had obvious high risk sexual behaviors with clients and 4/5 of them were not illicit-drug using FSWs;(4) 42.1%(16/38) of BED-CEIA positive specimens were false positives(＞155 days),but after eliminating the misclassified long-term HIV infected specimens,the BED-CEIA estimated HIV incidence were similar with that of the cohort survey among the same FSWs2.1/100PY vs.2.0/100PY;0.4/100PY vs.

注射吸毒行为是FSWs人群HIV感染的主要危险因素(aOR=9.8)：(2)连续参加过三次横断面调查的封闭式FSWs队列中，自报吸毒行为及高危性行为随调查时间均出现了降低的趋势，另外其性病感染率及尿吗啡阳性率的降低也印证了其自报高危行为特征的下降；(3)开放式FSWs队列中的HIV发病密度为1.4(95%CI0.5～3.3)/100人年，HIV新发感染FSWs与嫖客之间的高危性行为十分突出，以非吸毒FSWs为主(4/5)：(4)BED-CEIA阳性标本中的假阳性率为42.1%(16/38)，但在排除误检的既往HIV感染标本后，BED-CEIA及开放式队列研究估计的HIV发病密度十分接近2.1/100人年vs.2.0/100人年：0.4/100人年vs.0.6(来源：4eABC论f5f5文网www.abclunwen.com/100人年。

Based on the street framing system, the dissertation studies the street cross section elements design. It calculates lane width by vehicle property and design speed, gives the bikeway width by the need of bicycle parallel moving in various streets, summarizes the sidewalk forms, and gives the sidewalk valid width and public installations width of different streets according to the pedestrian feature.

在街道框架体系的基础上进行横断面各组成要素设计，根据车辆特性、设计车速计算了车道宽度值；根据非机动车并行行使的需要，结合不同类型街道非机动车特点，给出非机动车道宽度；总结了分析了小城镇人行道基本形式，基于行人的基本特性给出了不同类型街道行人有效宽度建议值和公共设施带宽度值。
