Model: XRD-Terra Nature of the Firm: Authorized Dealer Applications: XRD-Terra is the world's first portable analyzer XRD-Terra true sense is designed for NASA (NASA) developed a portable, automated X ray diffraction (XRD), Martian soil samples for the detection and analysis of ore samples Taiyuan X-ray diffraction to determine the geological formation of the Martian X-ray diffraction, and the support of micro-organisms present in organic compounds and environmental conditions were analyzed. Has equipped with "Spirit" and "Opportunity", successfully completed a geological expedition to Mars. XRD-Terra is a portable analyzer southwest Guizhou X-ray diffraction of the first truly global, U.S. NASA patent -7113265. Darwin's theory of kinematic diffraction theory called kinematic theory of X-ray diffraction. The theory of the Fraunhofer diffraction as a three-dimensional diffraction problems to deal with Anson X-ray diffraction that the scattering of each volume element of the crystal volume element of the scattering of other unrelated and scattered rays by crystals no longer be scattered. Although this treatment can be drawn sufficiently accurate diffraction direction, diffraction intensity can also be obtained, but the fundamental assumption that the kinematic theory is not entirely reasonable. Since scattered X-rays in the crystal will be scattered again, except in combination with the original ray, but also scattered radiation can be combined with each other. Darwin would soon realize this and make a correction in his multiple scattering theory.
