双曲线方程 meaning in English

hyperbolic equation

Conventional seismic data processing method uses hyperbolic equation to describe time - distance formula of reflection wave , error of this equation increases with the increase of heterogeneity , anisotropy and spread length
常规地震资料处理方法是利用双曲线方程来描述反射波时距曲线规律，此方程随着地层非均质性、各向异性和排列长度的增加，其误差变大。
Used dynamics equation to express the relation between the accumulation amount of no 3 - n leaching and time : urea , ammonium - bicarbonate and composed fertilizer can be expressed as equation yt1 / 2 = a + bt , complex mixed fertilizer can be expressed as equation 1 / y = a + bl / t . the accumulation leaching quantity of no 3 - - n with urea , ammonium - bicarbonate , composed fertilizer and complex mixed
随时间t的变化用方程进行拟合，结果表明ck 、碳按和复混肥处理，以双曲线方程l / y二a + bl八拟合效果最好，而尿素和复合肥处理则以抛物线方程y ， ’ / 2 = a十bt拟合效果最好。
