9303948 Evans This award provides one-half the funding necessary for the purchase of an image analysis system to be installed on the electron microprobe in the Department of Geological Sciences at the University of Washington. The University is committed to providing the remaining funds needed for the acquisition. The electron microprobe provides quantitative elemental microanalysis with a spatial resolution of one micrometer. The capabilities of the microprobe are used by geoscience students and senior research scientists in the fields of igneous and metamorphic petrology, as well as for studies in geomorphology and paleontology. The microprobe lab is also used in a variety of studies by archeologists, astronomers (studying meteorites) and biologists (studying hard parts) at the University of Washington. The digital imaging system will greatly facilitate all of their studies by enhancing the ability to view the spatial distribution of elements with respect to sample morphology, and by quantifying the size, shape, amount and distribution of selected sample components from digitized images. ***

9303948埃文斯这项奖励提供了购买图像分析系统所需资金的一半，该系统将安装在华盛顿大学地质科学系的电子显微探头上。该大学承诺提供收购所需的剩余资金。电子探针提供空间分辨率为1微米的定量元素微量分析。地学学生和资深研究科学家在火成岩和变质岩石学领域以及地貌学和古生物学研究中使用微探头的能力。微探测器实验室还用于华盛顿大学考古学家、天文学家(研究陨石)和生物学家(研究难的部分)的各种研究。数字成像系统将极大地便利它们的所有研究，因为它提高了观察元素相对于样品形态的空间分布的能力，并从数字化图像中量化了选定样品成分的大小、形状、数量和分布。***
