The characteristics of bicycle flow are analyzed based on observational data. The results show that the density of the queued bikes decreases lineally as does the width of the bike lanes. The relationship is based on scientific methodology applicable for calculating bicycle traffic capacity at signaled intersections.

为科学合理地解决城市道路信号控制交叉口自行车交通流通行能力的计算问题，在分析大量实测数据的基础上，对信号控制交叉口自行车交通流的运行特征进行了分析，得出自行车停车排队密度随交叉口自行车道宽度增加而线性递减的关系。

He said that the Hong Kong Tracker Fund of the then government for the purpose of the game with the international hedge funds, which concentrate superior forces to play the "annihilation", as long as the hedge funds would not have打跑a problem, and now the stock market,"the size of non-" play do not run, waiting in line to the listing of more and more companies are a lot of day do not buy one day, so even come up with 200 billion yuan to 3,000 billion yuan enrich stabilization fund, there are "one announced to buy the stock market on the up, revealed the news to sell a stock market or "situation.

他说，香港盈富基金为与国际对冲基金，集中优势兵力打"歼灭战"，只要游戏的目的，当时的政府作为对冲基金不会打跑一个问题，现在的股市，"大小非"玩不运行，排队的越来越多的公司上市是一个很大的一天不买一天，因此，即使拿出2000.0亿元至3000亿元元充实稳定基金，有"一宣布购买股市的上升，透露了这个消息出售股票或"的情况。

In other countries,this is not a problem:in America,where a queue-jumper has committed a misdemeanour rather than a cardinal sin,the response is loud and prescriptive:the offender is simply told'Hey,you,get back in line!

这在别的国家都不成问题：比方说在美国，加塞儿只是小错而不是大罪，对此人们会习惯的告诫，直截了当得对犯规者说："喂，说你啦，后面排队去！"

After the problem of speech mixing in an 8-point video conferencing system is solved, three queue models of the SSMS are designed in order to make the choices of the buffer size and the prefetching packet number more reasonable so as to save the memory space and reduce the algorithm delay.

在解决了8点会议系统中的多路语音实时混合问题后，为了使得算法中缓冲区大小的选取和预取数据量的分配更加合理以节省存储空间及减小算法时延，本文建立了三个有关SSMS系统的排队模型。
