Based on the observation data of meteorological stations,Doppler radar observation data of Ulanqab City,and ERA-5 reanalysis data,a snowstorm process in Ulanqab City from March 17 to 18,2022 was *** results show that this was a type Ⅱ snowstorm process generated under the joint influence of upper trough and ground low inverted trough and frontal *** main period of snowfall can be divided into two time stages,and the total snowfall was more in the south and less in the north,which was consistent with that of average specific humidity *** vapor conditions provided by strong water vapor transport and convergence,strong upward movement shown by large vertical velocity field,and the suction action of high-and low-layer divergence and convergence were the reasons for the hourly heavy snowfall on the 18^(th).During the process,radar echoes were mainly sheet-shaped,and composite reflectivity was 15-25 dBZ in most *** zero speed line in the first period was positively"S"-shaped,and there was warm advection and southwest *** the morning of the 18^(th),after the cold front transited the city,Ulanqab City was gradually controlled by northwest wind,and the snow tended to end.

研究应用空间句法考察了曼哈顿城市形态演变及曼哈顿街区合并对城市局部及整体城市形态的影响,以探讨其背后反映的城市形态与城市社会经济活动之间的互动关系。研究认为,曼哈顿城市形态具有弹性特征,使其在因街区合并等带来的城市形态演变过程中保持了较高的可达性,同时形成了具有多中心性及多样性的城市形态。不同功能合并街区呈现的差异化空间形态表明,城市形态对社会经济活动具有重要的支撑作用。本研究对中国高密度紧凑城市中的物质空间形态规划有重要的借鉴意义。

Fusing agent is used to help metal infiltrate into fiber bunches during infiltration manufacture of fiber reinforced Al-Mg alloy based composite wires. The agent could dissolve in water to form a kind of water-based solvent and then adhere on the fibers. But the solvent is not easy to distribute in carbon bunches. Therefore the supersonic method was used in this work. The critical infiltration pressure equation for the solvent infiltration was introduced into the supersonic pressure equation to obtain the relationship of supersonic parameters, location of the fiber bunches and radius of amplitude-changing rod.

该文应用空间句法理论和方法,通过实地观测汪口街道的步行人流密度,统计分析了村落空间形态的诸多变量与步行密度之间的系统关联。研究的目的是探讨村落的形态结构本身会多大程度地影响步行人流。初步的分析结果表明居民的步行运动模式主要受空间系统的整体组织关系特别是最短路径的选择因素的影响,而商业对人流的吸引作用对这种关系的影响有限。
