本文简介五山(广州)台采用“摆杆方位解析确定法”对水平摆工作方位检测与重调的情况。得知摆杆偏离初始平衡的角度达1.75°(东西摆)与0.2°(南北摆),表明以前资料有59.2％是在摆杆偏角超限状况下测得的。经重新调整后,仪器运行状态符合《规范》要求。文章还给出将以往资料归算至南北方向的公式,以利分析及交换资料之用。
This article describes the Wushan (Guangzhou) Taiwan using the “pendulum position determination method” on the horizontal pendulum working position detection and re-adjustment of the situation. It was found that the angle of deviation of the pendulum from the initial balance reached 1.75 ° (east-west pendulum) and 0.2 ° (north-south pendulum), indicating that 59.2% of the previous data were measured under the pendulum over-angle condition. After readjustment, the operating status of the instrument conforms to the “standard” requirements. The article also gives the formula for subtracting the historical data from the north-south direction for the purpose of analyzing and exchanging data.
