On this subject , chen wenxiang ' s using feedback servo mechanism to scale - up the measurement range on the shift by hore sensor and chen dongjun ' s study of a kind of hore shift sensor with feedback servo mechanism have achieve the rudimental results . it shows that using self - tracking or servo system to scale - up the measurement range of the hore sensor is reasonable 在这项研究工作上,陈文芗《采用反馈随动机构扩大霍尔传感器位移测量范围》 、陈东军《一种带有反馈随动机构的霍尔位移传感器研究》已经取得了初步的成果,他们的成果表明采用随动机构扩大霍尔元件的测量范围是有效可行的。
Scaling - up of patch model is necessary in the calculation of surface energy fluxes and evapotranspiration from remote sensing data . the simulation error of two - layer model caused by sub - pixel heterogeneity and discontinuity of surface geometry and physics were investigated using a number of data experiments 论文还分析了蒸散模型的空间尺度效应,通过一系列的模拟实验检验了双层模型中国科学院遥感应用研究所博士学位论文在不同地表非均匀状态下的尺度误差,并且根据通量尺度扩展的基本法则推导了双层模型参数的尺度扩展公式。
