查询词典 pedestrian crossing

In this paper, male sterile line of alfalfa was used to be improved with crossing, because the seed production of crossing is low. The affecting factors of seed production of male sterile line of alfalfa and its crossing progenies that are crossed with male sterile lines of alfalfa and good alfalfa that male is fertile were analyzed. The characteristics of female reproductive organs of male sterile line and its crossing progenies are analyzed in cell morphology. The genetic difference of male sterile line and its crossing progenies are analyzed in enzyme protein. The results showed: 1、Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plant BC1-2 that is the crossing progency of male sterile line of alfalfa and Medicago varia Martin.cv.'Caoyuan No.1'is higher than male sterile lines. Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plants BC1-19、BC1-21、BC1-22、BC1-23 that are the crossing progencies of male sterile line of alfalfa and Medicago sativa L.cv.

Two main problems of the main road pedestrian environment have found out: first, the main pedestrian realm of the main roads is incontinuous, lack genius loci and low service level; second, the joint part of the main pedestrian realm, including crosswalks and bus stops, are unsafe and inconvenient.The main causes of those problems from macroscopic viewpoint are analyzed.

提出目前城市干道步行环境存在两大问题：一、以人行道空间为主的"城市干道两侧主体步行空间"，存在空间不连续、缺乏领域感、部分设施服务等级过低等问题；二、以人行横道、公交车站等为主的"进入主体步行空间的交接性步行设施"，存在缺乏安全性和方便性的问题。

Based on the development of Urban Public Space, Modern Pedestrian Street and the"Place Theory", several basic design principles are put forward in this paper. And the basic structure of outdoor environmental design of Modern Pedestrian Street is built in the following five aspects: basic skill of Pedestrian Street, basic behavior pattern research of person, commercial location, landscape design principle, landscape design.

该文以城市公共空间和步行商业街的产生和发展为知识背景，根据"场所理论"提出基本设计原则，并根据自己对于"景观设计"的概念理解，从居住区步行商业街的基本功能、人的基本行为模式研究、商业定位、景观设计原则、景观设计等方面，由整体到枝节，建构了步行商业街景观设计的基本研究框架。

Field data of pedestrian flow was collected in Chinese comprehensive passenger transport terminal—Xizhimen underground station using video recording, and then selected and analyzed by statistic analysis software SPSS. Parameters relation models for pedestrian flow on different terminal facilities were established based on data statistics. The results show that the pedestrian flow-density relation model is quadratic equation in corridor; the flow-space relation model is quadratic equation when space is below a certain value and is logarithmic equation when space is above the value; the speed-density relation model is linear equation. The models on stairs show the similar characteristics, but the eigenvalue is different.

对国内综合交通客运枢纽——北京西直门地铁站行人流数据进行视频采集，采用统计分析软件SPSS对行人流参数数据进行筛选及拟合分析，建立了不同设施的行人流参数关系曲线及函数模型，研究结果表明，水平通道处行人流量与密度呈二次函数关系、流量与空间在某一临界点两侧分别呈二次函数及对数函数关系、速度与密度呈线性关系，楼梯处与之相似但特征点数值存在差异。

In this approach, the pedestrian characteristics investigation is made and some factors like randomness that affect pedestrian decision are ascertained and will be considered in pedestrian dynamics submodel.

据此，对城市区域中的行人特性作了详细的调查，指出了影响行人行为和决策的各种因素包括生理、心理、环境和随机性因素等。

The dislocable distribution of pedestrians in initial status as well as movement process enhances the interactions among pedestrians.The walking speed is adjustable because the pedestrian can move one or more small grids in each time step.The exit is figured more accurately because of the finer lattice,which reduces the probability of pedestrians passing the exit abreast. When one pedestrian walks in the middle of an exit and no pedestrian could share the exit with him,then the evacuation efficiency is decreased.

网格细化使得行人在初始状态以及运动过程中呈现错位分布的特性，行人的错位分布加剧了行人间的相互排斥；网格细化使得在每个时间步内行人可以运动不同的格子数，从而实现了速度的可调性；网格细化使得出口得以精确的网格划分，在错位分布的作用下，形成了多格子模型中特有的行人出口独占效应，大大降低了出口的利用率。
