    • A curved pyrolytic graphite crystal x-ray monochromator has at least one diffraction surface of graphite crystal for diffracting and monochromizing x-rays generated from an x-ray source so as to bend and/or converge the diffracted and monochromized x-rays, wherein the diffraction surface has a predetermined curved surface. In a method for manufacturing a curved pyrolytic graphite crystal x-ray monochromator, one or more pieces of polymer films are heated at a temperature predetermined in a range from 400.degree. C. to 3500.degree. C. so as to form carbonaceous films, and then, one or more pieces of formed carbonaceous films are superimposed, heated and pressed onto a predetermined curved surface of an isotropic graphite die at a temperature predetermined in a range from 400.degree. C. to 3500.degree. C., while applying a predetermined pressure onto the carbonaceous films provided on the isotropic graphite die, thereby forming the curved pyrolytic graphite x-ray monochromator of graphite crystal having a resulting curved surface corresponding to the predetermined curved surface.
    • 弯曲的热解石墨晶体x射线单色仪具有石墨晶体的至少一个衍射表面,用于衍射和单色从X射线源产生的x射线,以弯曲和/或会聚衍射和单色X射线,其中 衍射面具有预定的弯曲表面。 在制造弯曲热解石墨晶体x射线单色仪的方法中,将一片或多片聚合物膜在400℃〜3500℃的温度范围内加热,形成碳质膜,然后 在400℃〜3500℃的温度范围内,将一片以上的成形碳质薄膜叠加,加热并压在各向同性的石墨模具的规定的曲面上,同时向 设置在各向同性的石墨模具上的碳质膜,由此形成具有对应于预定弯曲表面的所得弯曲表面的石墨晶体的弯曲热解石墨x射线单色仪。
