论文摘要
在E. Podkletnov等人的作品中。 （例如[Physica C：SuperDoductivity，1992，第203卷，第441页）），描述了一个独特的实验，其中当将各种测试体的重量显着减小，当将各种测试物体的重量放置在超导体YBA2CU3O6+DELTA（YBCO）的旋转盘上方上方上方时。该磁盘处于超导状态（在20-70 K处），并经过交替（50 Hz-100 MHz）磁场。在其他实验室中复制该实验的许多尝试都没有成功。但是，已经开始了广泛的讨论，就“ podkletnov效应”的可能性质 - 位于超导体上方的物体的重量损失。在目前的实验工作中，已经获得了类似于Podkletnov效应的结果，但是，该效应发生在室温下。在我们的实验中，具有晶体水合物K2CO3X1.5H2O和分散的YBCO的气密容器在频率为50 MHz的磁场期间和0.5小时暴露于磁场中表现出部分重量的急剧损失。记录了与容器接近的各种测试机构的重量的变化。发现这些重量变化与人体的外表面积相关，并且不取决于它们的化学性质。重量变化对YBCO中的氧含量的依赖性依赖性，这表明在基础平面中存在氧sublattice的上层结构有序的区域中有显着的倾斜。这种倾角与TC对Delta（“ 60-K高原”）的依赖性中众所周知的倾角一致。讨论了这两种非凡现象之间在YBCO化合物中共存的两种非凡现象之间的联系 - 莫名其妙的重量变化和高温超导性。
In the works of E. Podkletnov et al. (for example [Physica C: Superconductivity, 1992, Vol. 203, p. 441]), a unique experiment is described in which a significant reduction in the weight of various test bodies was observed when placed above a rotating disk made of the superconductor YBa2Cu3O6+delta (YBCO); the disk was in the superconducting state (at 20-70 K) and was subjected to an alternating (50 Hz-100 MHz) magnetic field. Numerous attempts to replicate this experiment in other laboratories have been unsuccessful; however, a broad discussion has been initiated regarding the possible nature of the "Podkletnov effect" - the weight loss of objects located above the superconductor. In the present experimental work, results similar to the Podkletnov effect have been obtained, which, however, occur at room temperature. During our experiments, gas-tight containers with the crystal hydrate K2CO3X1.5H2O and dispersed YBCO exhibited a sharp loss of part of their weight during and after 0.5 hours of exposure to a magnetic field with a frequency of 50 MHz. Changes in the weight of various test bodies located in close proximity to the containers were recorded. It was found that these weight changes correlate with the external surface area of the bodies and do not depend on their chemical nature. A dependence of the magnitude of weight changes on the oxygen content in YBCO was obtained, which shows a significant dip in the region where superstructural orderings of the oxygen sublattice exist in the basal plane. This dip coincides in shape with the well-known dip in the dependence of Tc on delta (the "60-K plateau"). The possible connection between these two extraordinary phenomena coexisting in YBCO compounds - inexplicable weight changes and high-temperature superconductivity - is discussed.
