Big Cottonwood Creek | Utah Wildlife Forum Anybody ever fish BCC in the valley as it makes it's way through Holliday and into the Jordan River? I have fished it over the years with very mixed results, I have sained it and never find very many insects, pretty stumped by it Thanks for any feedback in advance
XRD图怎么看？ - 知乎 4 XRD可以用于定量分析哪些内容？ A 样品的平均晶粒尺寸，基本原理：当 X 射线入射到小晶体时，其衍射线条将变得弥散而宽化，晶体的晶粒越小， x 射线衍射谱带的宽化程度就越大。因此晶粒尺寸与XRD谱图半峰宽之间存在一定的关系, 即谢乐公式（Scherrerequation），下期会详细分析其原理与注意事项。
