光的直线传播

特别是其中的第三条描述了针孔成像实验，并用射箭的飞行来比喻光的直线传播。

Especially the third one describes the pinhole image formation experiment and analogies rectilinear propagation with the archery flight .

从波动理论出发，证明极限情况下光的衍射结果就是光的直线传播。

Conclusion that result of diffraction of light is rectilinear propagation in limited condition is demonstrated from wave theory .

根据光的直线传播原理，计算辐射在冠层内三维空间上传播和受冠层内面元截获的过程，建立了PAR在玉米冠层内三维空间上分布的模拟模型。

Based on the principle of geometric optics , a set of models have been developed to simulate the 3D PAR distribution in maize canopy by calculating the light propagation and interceptions among the facets in crop canopy .
