| description | The invention, which belongs to the technical field of acceleration measurement, relates to a microcrystalline-glass-cavity-based movable gravity measurement apparatus. The movable gravity measurement apparatus comprises a two-dimensional microcrystalline-glass vacuum cavity, a three-dimensional microcrystalline-glass vacuum cavity, an alkali metal source, and a differential pump tube. The two-dimensional microcrystalline-glass vacuum cavity is connected to one side of a three-dimensional cooling vacuum cavity of the three-dimensional microcrystalline-glass vacuum cavity by the differential pump tube; a suction device is connected to the other side of the three-dimensional cooling vacuum cavity; and the alkali metal source is connected to the two-dimensional microcrystalline-glass vacuum cavity. Besides, the differential pump tube is made of the same microcrystalline-glass material as those of the two cavities. According to the gravity measurement apparatus, the vacuum cavities are constructed by using the mi |
