Proceed from the principle of neural networks, the mechanism of mapping between input and output of neural networks was analyzed, and the BP algorithm for training the thresholds of neurons was derived. Based on the study to the distinguishability of input of networks, the effect of neural networks to distinguish-ability of characteristics was studied, and the optimizations of the structure of networks, learning rate, impulse factor, thresholds of neurons and initial weight of networks were completed. Through the experiments under fixed cutting regime and alternative cutting regime, the methods based on neural networks for tool wear monitoring were studied.

Not only was the nature of the benchmark revision a surprise, but so, too, was the anemic 1.1% growth estimated for 2Q02 -- less than half the downwardly revised consensus expectations; moreover, as recently as a month ago, most were looking for second quarter growth in the 3.5% range.
新数据中,令人吃惊的不仅在于对旧数据进行了下调,2002年第二季度的预测值更加惊人----低迷无力的1.1%,还不到公认预测值的一半,而公认值本来就已经下调了;就在一个月前,各界仍然普遍认为,第二季度增长率将达3.5%。
