The scale factor accuracy of superconducting gravimeters(SG) can be largely improved by a high repetition rate of calibration experiments.At stations where the availability of absolute gravimeters is
Hydroxypropylcellulose(HPC) films were prepared by casting with cellulose nanocrystals in the presence of anionic surfactant sodium dodecylsulphate(SDS) and cat
The Burris Gravity Meter~(TM) manufactured by ZLS Corporation, Austin/Texas, USA, is based on the invention of L&R(L. LaCoste and A. Romberg): The ZLS(zero-length spring). A digital feedback system(ra
The previous operation of the ZLS-Burris gravity meter using a PDA already provides a significant improvement of the operation of a metal spring gravity meter. But in the practical field work the obse
