| 摘要 |
<p>The invention relates to a device for measuring gravitational acceleration, which may be used for determining local discontinuities of the gravitational field, for determining the change of the gravitational acceleration, depending on the height where the measuring location is placed or produced during planetary alignment and during eclipses. The device may be also used for gravimetric prospectings and also in laboratories of the education and research institutions. The device comprises a vacuumed tube (1) hanging on a support (2) by means of a ball joint (3), in the vacuumed tube (1) a mercury column (14) being introduced, said column pushing on a pressure detector (5) located at the bottom of the vacuumed tube (1). The pressure detector (5) is connected to an electronic device (7), provided with a device (8) displaying the obtained results.</p> |
