Since the gamma function grows very quickly, it can easily overflow, and so the logarithm of the gamma function is often more useful than the gamma function itself.

由于伽玛函数的生长速度非常快，很容易溢出，所以伽玛函数的对数通常比更有用伽玛函数本身。

The lift-off angle of saltating sand grain follows LogNorm4 function distribution; lift-off horizontal velocity, vertical velocity and resultant velocity of saltating sand grain and falling angle and vertical velocity of saltating sand grain follow Gamma function distribution; falling horizontal velocity and resultant velocity of saltating sand grain follow Pearson IV function distribution.

跃移沙粒起跳、降落速度分布函数利用风洞实验获得的沙粒跃移运动的片断轨迹，反推出沙粒起跳角度服从LogNorm4函数分布，跃移沙粒起跳水平、垂直及合成速度均服从Gamma函数分布。

So we either need to remove the gamma from our textures ("linearize" them) before rendering, which can be done with a gammaCorrect node in front of them in the shader chain with Gamma set to 1/2.2, which is 0.455 rounded important: the gammaCorrect node works inversedly - the value we put in there is the desired gamma compensation value, not the actual gamma function itself!

所以在渲染之前我们也需要把纹理的Gamma值去除，这些可以在材质系统的前面用一个Gamma校正节点来完成，将Gamma值设置为1/2.2，就是0.455（重点：GammaCorrect节点使逆向工作的---在这儿我们输入的数值是期望得到的Gamma补偿数值，不是实际的Gamma自身的作用数值！

Finally, the thesis analyzes statistical laws of the maximum saltating height and saltating length of saltating sand grains and they follow Gamma function distribution. This is consistent with the results of water-sand motion. It shows that statistical laws of saltating height and saltating length of saltating sand grains are independent of the medium of flow. It is possible the nature of saltating sand grains.

最后，分析了沙粒跃移距离、跃移高度的相对量的统计规律，认为它们均服从Gamma函数分布，与在含沙水流中的研究结果一致，说明沙粒跃移运动的跃移高度与跃移距离的统计规律与流场、所处的介质无关，这可能是沙粒跃移运动的本质所在。
