简介：在这份报纸，我们在场深水里的一个点波浪吸收器的全面数字模拟。分析在频率和时间领域被执行。变换器与在举方向的自由的一度是一个二身体的浮点吸收器(FPA)。它的二部分被一个线性mass-spring-damper系统连接。在这研究使用的商业ANSYS-AQWA软件表现很好在考虑确认。速度潜力被假定不可压缩、无旋的流动获得。因此，我们在精力变换和设备效率上调查了波浪特征的效果，包括波浪高度和波浪时期，以及设备直径，草稿，几何学，和抑制系数。验证模型，我们从类似的实验把我们的数字结果与那些作比较。当考虑特定的条件时，我们的学习结果能清楚地帮助最大化变换器效率。

简介：在这篇文章，我们认为非线性的秒顺序的二个积极答案的存在是三点的单个边界价值问题：?u(t)=f(t，u(t))为，使=0和u()=u(1)遭到到u(0)的所有t(0,1)0,1)，[0,1)，并且是一个积极参数。非线性的术语f(t，u)是nonnegative，并且可能在t=0，t=1，和u=0单个。由固定的点索引理论和近似方法，我们证实那在那里存在*(0，+]以便上述问题为任何东西有至少二个积极答案(0，*)在非线性的条款f上的某些条件下面。
