平方根的 meaning in English

Examples
- Consider the square root function used in the previous example
使用在早先用过的平方根的例子。 - Seventeen minus the square root of nine , plus sixty - five over five , minus four times three , equals fifteen
十七与九的平方根的差加上六十五除以五的商的和，减去四与三的积，等于十五。 - For example , if a function to calculate the square root can only handle non - negative numbers , you can have an assertion that the input argument is 0
例如，如果计算平方根的函数只能处理非负数，您可以设置一个输入参数> = 0的断言。 - The improved algorithm not only inherits the fast convergence trait from rls and realizable systolic array from qr _ rls , but also eliminates square - root operation and gets directly equalizer output signals from systolic array . so this algorithm has more simple operation , faster executing speed , less hardware resource and lower hardware cost . some different equalization algorithm are imitated on the qpsk communication system with multipath channel
其次对一些成熟的自适应均衡算法(如lms算法、 rls算法、 qr _ rls算法、逆qr _ rls算法)进行了分析;介绍了一种改进后的无平方根的qr _ rls算法,该算法不但继承了rls的快速收敛特性和qr _ rls算法的systolic阵列可实现性,还取消了qr _ rls算法的平方根运算,使算法在硬件实现时运行速度更快,占用资源也更少,同时该算法还可由systolic阵列直接得到均衡后的输出信号,运算量更小。
