用于新型空间推进和能源产生的极端重磁场和类重力场物理学
Physics of Extreme Gravitomagnetic and Gravity-Like Fields for Novel Space Propulsion and Energy Generation
摘要：
2006年，Tajmar等人报告了在低温下从小型Nb环测量到的极端重力磁场，其比从GR（广义相对论）获得的重力磁场大18个数量级。Cifuolini在2004年的实验和NASA-斯坦福重力探测器-B在2007年的实验证实了Lense-Thirring效应，正如GR（由旋转的大质量物体，即地球产生的重力磁场）预测的那样，误差在10%以内。2007年，Graham等人测量了由旋转的低温铅盘产生的重力磁场。尽管这些测量结果并不是决定性的（激光陀螺仪的精度不足以产生足够小的标准偏差），但他们的实验似乎看到了Tajmar等人早先报道的相同现象，称为奇偶性违反。这意味着由低温旋转环或盘产生的重力磁场基本上变化并且改变顺时针和逆时针旋转方向的符号。因此，实验的情况是矛盾的。一方面，GR已被证实，而在同一时间，似乎有实验证据表明，极端重力磁场的存在，不能产生的运动的大质量。如果这些实验能够得到证实，它们就清楚地表明存在着非牛顿性质的附加引力场。正如GP-B实验所示，测量GR的重力磁场非常困难。因此，应该存在一种新的物理机制来产生类引力场，这也可能为类似于电磁技术的引力工程提供关键。
英文摘要：
In 2006 Tajmar et al. reported on the measurements of extreme gravitomagnetic fields from small Nb rings at cryogenic temperatures that are about 18 orders of magnitude larger than gravitomagnetic fields obtained from GR (general relativity). Cifuolini in 2004 and the NASA-Stanford Gravity Probe-B experiment in 2007 confirmed the Lense-Thirring effect as predicted by GR (gravitomagnetic fields generated by a rotating massive body, i.e. Earth) within some 10%. In 2007 gravitomagnetic fields generated by a rotating cryogenic lead disk were measured by Graham et al. Though these measurements were not conclusive (the accuracy of the laser gyrometer was not sufficient to produce a standard deviation small enough) their experiment seems to have seen the same phenomenon reported earlier by Tajmar et al., termed parity violation. This means that gravitomagnetic fields produced by the cryogenic rotating ring or disk vary substantially and change sign for clockwise and counter-clockwise directions of rotation. The experimental situation therefore occurs to be contradictory. On the one hand GR has been confirmed while at the same time, there seems to be experimental evidence for the existence of extreme gravitomagnetic fields that cannot be generated by the movement of large masses. If these experiments can be confirmed, they give a clear indication for the existence of additional gravitational fields of non-Newtonian nature. As was shown by the GP-B experiment, measuring gravitomagnetic fields from GR poses extreme difficulties. Therefore a novel physical mechanism should exist for the generation of gravity-like fields, which might also provide the key to gravitational engineering similar to electromagnetic technology.
