- Two - layer model integral method for turbulent boundary layers
湍流边界层的两层模型积分法 - Heat fluxes estimated from radiative temperature by this model is more accurate than other regular corrective methods . two - layer model has been proposed for many years but was difficult to apply in remote sensing because component temperature were unavailable in traditional thermal sensors . a new airborne multi - angular thermal sensor system and retrieved soil and canopy temperatures were used to solve two - layer model , and the simulated heat fluxes show much better accuracy than the results from one - layer model especially above dry surfaces
双层模型虽然提出很多年了，但在应用中一直存在信息不足，求解困难的问题，本文用最新多角度热红外遥感数据? ? ? amtis系统反演的组分温度，首次实现了双层模型在遥感中的应用，结果表明，在输入参数精度相近的情况下，双层模型模拟的通量误差远小于单层模型，尤其在土壤干旱，表面温度较高的地表，双层模型的理论优势在计算中表现得更加突出。 - And this is the first full application of two - layer model in remote sensing . from separated evaporation and transpiration through the model some important field parameters can be derived , such as canopy resistance , co2 flux and crop water use efficiency . a simplified two - layer model was also presented in case of that only radiative temperature is available
在组分温度的帮助下，实现了土壤蒸发和植被蒸腾的准确分离，并且用植被蒸腾速率反算出冠层气孔阻抗、二氧化碳通量、以及作物群体水分利用效率等农田关键参数，是遥感获得此类参数的新思路。 - ( 2 ) a management cepdp framework with wfms as its kernel was established by the support of pdm platform . the paper formally defined a general layered model of project management and introduced its management mechanism . an operational two - layer model was given according to the engineering practice
文章形式化地定义了一种通用的分层项目管理模型，分析了它的管理机制，在此基础上，结合工程实践，提出一种实用的二层项目管理模式；论文引入项目任务流和项目文档流的概念分析了项目的分解机制。 - For the case of transporting suspended fine sand , a single - fluid model is used to calculate the flow resistance by solving the navier - stokes equations . the computed agrees well with the measured . and for the case of transporting medium - sized sand , a two - layer model is used and the model produces a good agreement with the experiment data
对管道输送细沙悬移质的流场，采用单流体模型进行数值求解n - s方程，计算结果与实验资料相吻合;对具有分层流动的中沙管道水力输送，采用两层代数模型进厅了计算分析，阻力损失的预测结果与实验吻合较好;最后对管道输送粗沙的阻力特性和运动机理进行了分析探索，提出了进一步研究的方向。
