大气混合层高度的确定与计算方法研究

利用多个飞机场的气象资料对河北省及京、津地区的大气混合层高度进行研究,采用３种方法对大气混合层高度进行确定,把不同方法所得结果与实测值比较、分析后发现,干绝热法和经局地气象条件修正后的罗氏法是确定大区域大气混合层的最佳方法。利用离散点最小二乘曲线拟合原理得出精确度较高、计算简单的混合层高度计算公式。     

A new approach of drawing airport noise contours on computer based on Surfer

Noise contours are used to describe the extent of airport noise pollution and to plan land use around airports. The LWECP, (weighted equivalent continuous perceive noise level) recommended by ICAO( International Civil Aviation Organization) is adopted as airport noise rating parameter in this paper. With the help of various mathematical models in the software Surfer, noise contours can be drawn automatically by the completed program in Visual C Code. Corrections for thrust, velocity, atmospheric temperature, humidity and lateral ground attenuation are also considered in the new method, which can improve the efficiency of drawing contours. An example of its use for drawing noise contours of an airport in Zhejiang Province of China is proposed and the predictions and the measurements show agreements well.     

暗访“快捷驾证”办证点

在晋江飞机场前的和平中路，有一个舶来的“汽车培训中心”，这个培训中心既没有教练，也没有教学场地，但可以让想有驾照的人拥有驾照，这个汽车培训中心叫做“鹰潭市汽车培训中心”（见右图）。此外，过了这个“村”，还有另一个只闻其声不见其影的“隐形店”，也是在晋江市内。[第一段]     

银川河东机场三期扩建供电规划

对银川河东机场三期扩建工程供电现状及用电负荷增长进行分析,提出了河东机场三期扩建工程供电的合理建设规划。结果表明:该方案既解决机场供电线路和净空限高之间的矛盾,又避免了对机场自然保护区林带的破坏。
