2.
Based on an analysis of the collected data of various lane widths by computer,the distribution of initial headway,saturation headway and a simple formula to estimate the start-up lost time in each cycle were obtained,and the quantitative mathematical model between lane width and saturation headway as well as saturation flow rate was derived.
通过编写计算机程序对数据分析处理,给出饱和车头时距的分布、初始时距分布、饱和流率估算值及其单个周期内的启动延误估计;深入考虑了车道宽度对初始时距、饱和时距、饱和流率及启动延误的影响,给出了车道宽度与饱和时距、饱和流率的关系模型,并对模型中给出的结论与美国的HCM 2000(道路通行能力手册)中的结论作了进一步的比较分析。
3.
By this models, this paper calibrates some factors which affect the saturation flow rate, and calibrates the revision coefficient fw on the basis of the relationship between the road width and the bus velocity.
在此基础上，对影响饱和流率的部分因素的修正系数进行了标定，基于车道宽对车速的影响程度确定车道宽修正系数。
6) Saturation ration of DO

补充资料：低出生体重儿发生率
低出生体重儿发生率
指某地区年内每100名活产数中，出生体重低于2500g的新生儿发生数之比值。其计算公式为：低出生体重儿发生率＝〓〓某年某地区出生体重〓〓低于2500g的新生儿数〓〓年内该地区活产数〓〓×100%出生低体重儿有因孕龄低，而体重与孕龄相符，其预后与早产儿相似。有孕龄达足月而体重低于2500g者为足月低体重，其预后常不同于早产儿。足月低体重儿死亡率常较早产儿低，即使存活者其智力发育也常较慢，不如早产儿存活者。
