Description
Изобретение относитс к геофизике, разрабатывающей способы измерени элементов гравитационных полей.The invention relates to geophysics, which develops methods for measuring the elements of gravitational fields.
Известны способы измерени вторых производных потенциала силы т жести в отдельных точках, состо щие в том, что измерение на каждой точке ведут в нескольких азимутах .Methods are known for measuring the second derivatives of the force of gravity potential at individual points, such that the measurement at each point is carried out in several azimuths.
Этим способом нельз проводить непрерывные измерени вторых производных.In this way, it is not possible to conduct continuous measurements of second derivatives.
Дл устранени этого недостатка, согласно предложенному способу, измерени провод т сначала всеми вариометрами, затем через определенные промежутки времени часть вариометров эталонируют, продолжа измерени остальными, причем интервалы эталонировани устанавливают более короткими, чем интервалы измерений. Способ позвол ет вести непрерывные измерени вторых производных потенциала силы т жести.To eliminate this drawback, according to the proposed method, the measurements are carried out first with all variometers, then after a certain period of time, some of the variometers are calibrated, continuing the measurements by the others, with the calibration intervals set shorter than the measurement intervals. The method allows continuous measurements of the second derivatives of the gravity potential.
Предложенный способ можно реализовать, например, с помощью двух вариометров, каждый из которых содержит два взаимно перпендикул рных чувствительных элемента с вертикальными крутильными нит ми, оба конца которых жестко св заны с корпусом.The proposed method can be implemented, for example, using two variometers, each of which contains two mutually perpendicular sensing elements with vertical torsion wires, both ends of which are rigidly connected to the housing.
раметры, например начальные углы закручивани нитей подвеса фо. Измерени провод т следующим образом. Непрерывно измер ют вариометрами вторые производные в течение некоторого интервала времени. Затем один из вариометров эталонируют, а вторым вариометром продолл ают измер ть производные, использу результаты измерений при эталонировании первого вариометра. После эталонировани в течение некоторого времени вновь ведут наблюдени обоими вариометрами, а затем эталонируют второй вариометр, продолжа проводить измерени .Measurements, for example, the initial twist angles of the suspension threads pho. The measurements are carried out as follows. Continuously measured by variometers, the second derivatives for a period of time. Then one of the variometers is calibrated, and the second variometer is continued to measure the derivatives, using the measurement results when calibrating the first variometer. After being calibrated for some time, they are again observed by both variometers, and then the second variometer is calibrated, continuing to measure.
Продолжительность цикла устанавливают исход из требуемой точности и стабильности параметров вариометров.The cycle duration is determined based on the required accuracy and stability of the parameters of the variometers.
Предложенным способом можно осуществл ть непрерывные измерени вектора полного горизонтального градиента силы т жестиBy the proposed method, continuous measurements of the vector of the full horizontal gravity of gravity can be carried out.
