They do format the screen and accept keystrokes,but they can't handle other aspects of presentation logic,such as screen sequencing and data validation. 它们的确编排了屏幕显示格式，并接收敲键输入，但它们不能处理表示层其它的逻辑操作，如屏幕显示时序排列和数据验证等。
The next step toward quantum information processing with impurity spins is controlling the coupling between two spins to perform quantum logic. 因此，以杂质自旋做量子资讯处理的下一步，就是操控两个自旋间的耦合，以执行量子逻辑运算。
In this paper, it is extended to multi-valued logic after analyzing implementation of binary logical operations based on MLP. 本文在分析二值感知器神经网络实现二值数字逻辑运算后，将其推广到多值逻辑。
