fēi niú dùn xì tǒng]
[流] non-Newtonian system
- 介绍了一种用于精密测量非牛顿流体流变学特性的测试系统。
A precise measuring system for the rheological behavior of non-Newtonian fluids is introduced. - 利用拟牛顿算法确定最优控制输入信号,可以得到非完整系统运动的优化轨迹。
And by using Quasi-Newton method, the optimal control input of nonholonomic system can be found. - 由于管网各管段的水力参数均系非线性方程决定,因此,系统工况可采用牛顿法求解。
Because the hydraulic parameters of each component of the network are determined by a nonlinear flow formula, the solution to this system can be got by the Nexvton Raphson method.
