扩散方式
Examples
- Meso - scale atmospheric diffusion patterns and time scales over beijing area
北京地区大气中尺度扩散模态和时间特征分析 - Diffusion patterns ; time scales ; random walk simulation ; beijing area ; historical state
扩散模态时间尺度随机游走北京地区历史背景 - After analysis on the process of technical innovation diffusion , it introduces the diffusion pattern of technical innovation , points out that different pattern is lies in the different choice of research angle , the different type enterprise has its own effective technical diffusion pattern that most suits it ; at the same time it also proposes in the diffusion system which factors are affecting the technical innovation diffusion
在对技术创新扩散过程分析后,介绍了技术创新的扩散模式,指出模式的不同只是在于选择的研究角度不同,不同类型的企业有最适合自己的有效技术扩散模式;同时也提出扩散系统中哪些因素影响着技术创新扩散。 - To investigate the space / time distributions and occurrence and evolution of such events , the diffusion pattern over deserts , turbulent transfer features in sandstorm weather , the particle size distribution , mass concentration and its distribution , optic properties , chemical composition and physical factors responsible for the initiation of raising sands , we made integrative observation and sounding of sandstorms deep in the large - scale desert area , including tengri , badanjilin and maowusu , with the items consisting of micrometeorological measurement , 3d wind observation , data from kb - 120 and anderson samplers of mass concentrations of sands with their spectrum , the distribution of aerodynamic particle sizes from the aps3310a , retrieval of aerosols " optic depth from sunphotometer data , assay of the chemical composition by means of neutron activiation analysis ( naa ) and integrated study of all related factors for causing sandstorm to occur , based on the observations of all kinds
利用所取资料，系统分析了不同强度沙尘天气条件下沙尘气溶胶质量浓度和质量浓度谱、粒子谱分布、光学厚度、化学组分等特征；综合分析了影响沙尘起动的诸物理因子在沙尘起动中的作用；用沙尘输送模式对一次沙尘暴天气造成的泥雨过程的形成机制进行了模拟。历史气象资料统计分析表明，沙尘暴有其高发期( 4 、 5月)和高发时段( 14 - 20时) ， 14时到20时之间发生的沙尘暴约占沙尘暴总次数的66 。扬沙和沙尘暴天气条件下，湍流动量通量和湍流感热通量都是重要的湍流交换，沙尘暴发生前近地层的超绝热不稳定对沙尘暴天气有加强作用。
