光通量密度

随着种植密度的增大，不同株型品种群体的光通量密度降低。

PAR in the hybridizations with different plant-type reduced with the rising of planting densities .

计算结果显示该模型提供了更加合理的光通量密度分布预测，得到的光分布接近蒙特卡罗模拟，而且能更加方便地应用到光传输相关的数值模拟中。

Computation results showed GD model provided more reasonable predictions of light fluence rate distribution than BS and DA model , and the light distributions were similar to Monte Carlo ( MC ) simulation but more convenient when used in numerical simulation of light distribution related applications .

介绍了一般光源以及作为光度学基础的黑体辐射及其光谱分布的基本规律，并在此基础上介绍了光能量、光通量、发光强度、光通量密度、亮度等光度学相关概念。

In this paper , based on the discussion of light source and blackbody radiation and their spectral distributions , several photometric concepts such as luminous energy , luminous flux , luminous intensity , luminous flux density , and luminance are introduced .
