论文摘要
我们研究固体玻璃回流器的光学性质是否会影响重力$ g $加速度的值，这是通过在绝对弹道重量表中放置固体和开放式逆流电流来确定的。逆转录器具有等效的光学中心，并从相同位置，同一重量表中从相同的高度掉落，同时记录与400条条纹的固定条纹分离间隔相对应的时间数据。两种类型的后电流的数据都使用商业软件处理，以及基于对参考光束和测试梁之间相位差的相对论处理的独立开发软件，以及对频率调制效果的现实处理，并在干扰信号上调制指数$β\ gg 1 $。在应用极地运动，气压接收，潮汐和海洋装载的校正之后，我们发现与两种类型的反向电流确定的$ g $的值（无论是使用商业软件处理还是我们独立开发的软件）之间的一致性。我们建议两个计算相对论校正的程序；这两种方法同意比.01 $μ$ gal更好。
We study whether the optical properties of a solid glass retroreflector influence the value of the acceleration of gravity $g$ determined by dropping both solid and open retroreflectors in an absolute ballistic gravimeter. The retroreflectors have equivalent optical centers and are dropped from the same height, at a fixed location, in the same gravimeter while recording time data corresponding to fixed fringe separation intervals of 400 fringes. The data for both types of retroreflectors are processed with commercial software, as well as with independently developed software based on a relativistic treatment of the phase difference between reference beam and test beams, and a realistic treatment of the effect of frequency modulation, with modulation index $β\gg 1$, on the interference signal. After applying corrections for polar motion, barometric admittance, tides, and ocean loading we find agreement between the values of $g$ determined with both types of retroreflectors, whether processed with commercial software or with our independently developed software. We suggest two procedures for computing relativistic corrections; the two methods agree to better than .01 $μ$Gal.
