单词	electrometer
释义	electrometer /ˌɪlɛkˈtrɒmɪtə / noun Physics An instrument for measuring electrical potential without drawing any current from the circuit.To detect the small resulting current, she used an electrometer of an excellent design created by Pierre and his physicist brother, Jacques, some years earlier.... Hertz generated cathode rays inside an apparatus that included an electrometer to measure the electrical charge of the rays. Shortly after Antoine Becquerel and others developed the electrometer, John Mothée Gaugain made the first precise measurements of pyroelectric charges in 1859. Derivatives electrometric /ˌɪlɛktrə(ʊ)ˈmɛtrɪk/ adjective ... Simple electrometric methods were tested to estimate microbial activity in hypereutrophic aquaculture ponds. The gravitational constant G can be determined by an electrometric measurement using a group of current-bearing coils. electrometry noun ... Significant modification pattern of skin electric activity after laser irradiation has been monitored at 16 acupuncture points location, by digital electrometry and digital photopletismography. We thus show that high-resolution electrometry is realizable at room temperature and competitive with alternative low temperature (<10 K) solutions. In the present work we consider the possibility of using micromechanical electrometry to measure directly the fluctuating SET island charge due to electrons.
