【摘要】 计算井水位气压系数、固体潮系数和海潮系数以前主要在时间域内一般用回归分析的方法。本文给出了在频率域内计算这三种系数的新方法。由于新方法是建立在波动理论和振动理论的基础上,所以它有更明确的物理意义。它不仅可以计算出各种谐波不同频率的响应系数,而且还能较细地考虑各种响应产生的位相滞后问题。因而它比在时间域内的计算方法更接近于客观实际情况。更多还原

【Abstract】 Formerly, the barometric, solid tide and sea tide coefficients in water level change were usually calculated by means of regression analysis method in the time domain. In this paper, a new method for calculating the three kinds of coefficients in the frequency domain is introduced. The new method has clear meaning of physics because it is based on the wave and vibration theories. It can not only calculate the response coefficients of each harmonic wave in different frequencies, but also consider the phase lag that every response produces. Therefore, it is closer to the objective reality than the former analyses in the time domain.更多还原
