1. Many, many times I have sat and thought about that the first day, and how for a few fleeting mom ents I am there, feeling again what is like to know true love for the very fir st time.
多少次我再次坐下，不断追忆那天的点滴，不断回味那些飞纵的瞬间，重新体会一见钟情的美丽。
2. The active constraints are updated iteratively during the iterative process, until the true active-set of the problem is found. Algorithm analysis and application in the constrained least-squares design of FIR filters shows that the PLS algorithm consumes far less amount of computation than the popular active-set methods.
将该算法应用到FIR滤波器的约束最小二乘设计中，算法分析及约束FIR滤波器的设计例子都表明该算法的计算量远小于目前最流行的二次规划算法&有效集方法。
