他用了整整12年的时间,最终破解了困惑水波界近半个世纪的缓坡类方程。他用了12年,攀登一个缓坡;呕心沥血,只为解一个方程。他,就是破解了困惑水波界近半个世纪的缓坡类方程的广西民族大学教授刘焕文。缓坡方程是线性水波理论中最有用的方程,其雏形最早由美国加州大学学者伊卡特于1951年建立。1972年,荷兰德尔夫特理工大学学者贝克霍夫导出了另一个低一维的偏微分方程,被水波界公认为缓坡方程的经典形式。但近半个世纪以来,缓坡方程一直以“隐式”形式示人,即相应偏微分方程的系数为空间变量的隐函数。
He spent a full 12 years, eventually cracked the gentle slope wave equation of nearly half a century. He spent 12 years, climbing a gentle slope; work hard, only to solve an equation. He is Liu Huan-wen, a professor of Guangxi University for Nationalities, who has solved the gentle slope equation that has perplexed the water wave circle for nearly half a century. The gentle slope equation is the most useful equation in linear water wave theory. The prototype was first established in 1951 by Eccate Scholar, University of California, USA. In 1972, Baker Hof, a scholar at Delft University of Technology in the Netherlands, derived another low-dimensional partial differential equation that was recognized by the wave front as the classical form of the gentle slope equation. However, for nearly half a century, the gentle slope equation has been shown as “implicit”, that is, the coefficient of the corresponding partial differential equation is the implicit function of the spatial variable.
