Tension wood is considered to be an important defect by the wood processing industries. A considerable amount of research has been done to determine the presence and structure of tension wood; however...
喷雾液动态表面张力与雾滴粒径关系(Correlations between Dynamic Surface Tension and Droplet Diameter)
动态表面张力 雾化 雾滴
2009/9/11
为了描述喷雾液的动态表面张力与雾滴粒径的关系,用粒度分析仪对不同表面张力喷雾液喷雾时形成的雾滴体积中径D50进行了研究,重点考察了喷头尺寸、喷雾压力对D50的影响。结果表明:喷雾液0.023s时的动态表面张力值γ0.023越低,所形成的雾滴D50越小,D50与γ0.023呈线性相关;喷雾压力相同时,随着喷头尺寸的增大,喷雾液动态表面张力的改变对雾滴粒径的影响增大;喷头尺寸相同时,随着喷雾压力的增大...
Nitrogen Fertiliser Recovery and Yield Response of Greenhouse Grown and Fertigated Tomato to Root - Zone Soil Water Tension
Fertigation N-fertiliser recovery N-fertiliser concentration 15N soil-water tension tomato
2009/1/13
Tomatoes were grown in a plastic greenhouse under 2 irrigation programmes and four N-fertiliser concentrations (0, 100, 150 and 200 mg N l-1) of irrigation water. P and K concentrations were kept con...
Analysis of field tension disc infiltrometer data by parameterestimation
soil hydraulic properties tension disc nfiltrometer parameter estimation numerical modeling
2008/11/26
Using numerically generated data, we previously showed that it is theoretically possible to estimate the soil hydraulic functions from the cumulative infiltration curve measured with a tension disc in...
