双语例句

1
The search direction is formed by using gradient projection, and the search directions and functions are controlled effectively by the sign functions.
利用梯度投影构造搜索方向，并使用符号函数对搜索方向和搜索函数进行有效的控制。
2
The proposed stable feedforward filter makes the control switching with sign functions to produce a continuous and measurable signal so that the actual control law is smooth.
前置滤波器使带有符号函数的控制切换产生连续可测信号，实际控制律是光滑的。
3
The sample code provided with this article presents the sign in and sign out functions from within the same portlet, but you can implement the two functions in separate portlets, if you wish.
本文中提供的示例代码显示了同一Portlet中的登录和注销功能，但是，如果愿意，您可以在单独的Portlet中分别实现这两种功能。
