A general-purpose, multifunction light-scattering instrument has been developed at the NASA Lewis Research Center for Space Shuttle and Space Station colloid crystallization and other microgravity experiments. For a single sample, the instrument can measure two-dimensional Bragg scattering from 0.5 degrees to 60 degrees , dynamic and static light scattering from 10 degrees to 170 degrees , the shear modulus of samples before and after crystallization, and digital color images of the sample. A carousel positions any one of eight 3-ml samples into the test position for separate experiments. Program challenges and flight results from the STS-83 Space Shuttle mission are discussed.
美国国家航空航天局刘易斯研究中心已研制出一种通用多功能光散射仪器,用于航天飞机和空间站的胶体结晶及其他微重力实验。对于单个样品,该仪器可测量0.5度至60度的二维布拉格散射、10度至170度的动态和静态光散射、结晶前后样品的剪切模量以及样品的数字彩色图像。一个转盘可将八个3毫升样品中的任何一个置于测试位置,以进行单独实验。文中还讨论了STS - 83航天飞机任务中的程序挑战和飞行结果。
