Modulated Source Eotvos Experiment (Physics)

一项异常灵敏的调制源Eotvos实验将在华盛顿东部Snake River上的一个大船闸旁进行，以限制中程物质依赖的“引力”的存在。作者在1988年夏天进行的一项原型实验限制了积极的“第五种力量”效应。重要的是要用一个明确的衡量标准来解决这种可能性。一个已经在耶鲁大学组装的便携式实验室已经用于原型实验，将在1990年夏天被转移到小鹅锁进行进一步测量。钟摆设计的改进将使实验比原型实验至少灵敏一个数量级，预计新的测量将对这种效应的存在设定明确的限制。

An unusually sensitive modulated-source Eotvos experiment will be conducted next to a large lock on the Snake River in eastern Washington to put limits on the existence of an intermediate-range material-dependent "gravitational" force. A prototype experiment conducted by the author during the summer of 1988 placed limits on a positive "Fifth Force" effect. It is important to settle this possibility with a definitive measurement. A portable laboratory already assembled at Yale University and already used in the prototype experiment will be moved to the Little Goose Lock during the summer of 1990 for further measurements. Improvements in the pendulum design will make the experiment at least one order of magnitude more sensitive than the prototype experiment and it is expected that the new measurements will set definitive limits on the existence of this effect.
